Arbitration and Law - Essay Example The problem, however, is that even when arbitration takes place, the disputing parties will continue to engage the problem through additional courts in order to come to the best possible resolution for their interests. The following essay discusses the issues of arbitration, first by engaging the question of disputes in arbitration and the consequences to the courts, then through the exploration of a case study, and then finally through undergoing an investigation of the events within the case study. Privity of Contract Privity, in legal terms, refers to a relationship that develops between parties in regard to the property, promises or warranties of a contract. The privity of contract concept is to ensure that only parties that are involved in a contract are actually part of the entirety of the process and included in all subsequent actions. Disputes concerning the privity of contract result from engaging the contract for who is able to participate in the process. The limitation of privity prevents a great many lawsuits by those who believe they have been affected by the actions of a party, but who is not directly a part of the contract and are not able to create liability claims because they are not a part of the contract.1 Horizontal and Vertical Privity Horizontal privity occurs when a third party is the recipient of an item. When an item or benefit in question is intended for a third party, then horizontal privity is in place. Vertical privity occurs when an independent contract is in place with one of the parties of a contract between two parties. If A has a contract with B and B has a contract with C, vertical privity is in place between A and C. The consumer rarely has any rights in terms of privity. The laws in regard to consumers was revised in the Contract Act of 1999 in which the Rights of Third Parties were addressed so that â€Å"...a third party may not enforce a contractual provision, either if the contract contains an express term to that effe ct, of if it purports to confer a benefit upon him†.2 The problem with consumer relationships to the process is that there is no implied position within the contract for the consumer. Arbitration Arbitration is the process by which two parties enter into an agreement to choose privately defined proceedings in which to settle their differences. The arbitration process is internationally recognized as a resource through which disputes between internationally represented businesses can find resolutions without clogging court systems and without disputes about jurisdiction in regard to nation.3 Disputes are defined by any disagreement that occurs during the process of the contract relationship. Disputes are more often handled by arbitration that has been defined within a contract. According to Harris, Planterose, and Tecks, â€Å"This will distinguish the procedure, the application of any statute and the finality of the intended process from other options, such as a decision by a ny expert of adjudication†

The management of change is not an easy process and needs to be properly supervised. Managing the change effectively will help in a proper control and also accelerate the change in a proper way and help in the future achievements. There are many studies that study the other aspect of the management and that are the human side of the subject. People do not accept change in a positive way and it is more seen when it is when related to the culture and the tradition of the people. In case of Nissan Motor Manufacturing (UK) Limited (NMUK) they should be evaluating the risks that should be covering the current situation in order that a successful change management process is amplified. Figure Change Management Model Identify the Change Prepare to Change Sponsor Target Change Agent Culture History Resistance Current Desired Implement the Change Monitor the Change Delta Plan the Change Communication As per the study of Cole (1997) it can be said that in any particular organisation at a given point of time there will be a number of factors that will act as a driving force and others will be acting as a restraining force. The force field model is as summarised as below These days there has been a clear showdown in the production and the improvement and also development in all areas of the manufacturing. It is more than evident in the field of automobiles where the recession has played a major role and also it has affected a lot in these circumstances. The use of the solutions given by the company has helped a lot in the reduction of the cost of production and has been able to generate some ample revenue for the company. The change in the organisation has to be kept in mind the different processes of change and also the different modern technology that will help in the success and growth of the company. The effectiveness and the efficiency of the system for which the company has been employed will help them in each and every situation and also help in the reducing of the mistakes and reduction of the defects of the company. It also helps them with the solutions and the full documentation of the provision of the access for the conservation and the stability of the information to include the best practices in the organisation. The system will help the customers access to the most important data that they require and that too in a very period of time which will help in the reduction of the costs and help in the reduction of the expensive change in the engineering processes. The most important steps which will help in the control of the change management process and also to implement it without undergoing any other failures which will hamper the progress of the successful implementation of the system are The managers and the in charge personnel of the department should be clarified in the idea of the change management and should be cleared in their minds about the change in the process that is being going on. The staff should be given the detailed explanation of why such a change is going on and also be told about the advantages of it. The development of the future plan will help in the implementation of the system without any disruption. The preparations for the implementation of the plan will help in the process with the presence of the experts and the specialists that were available for this. RECOMMENDATIONS Taking into consideration the above analysis it can be said that in order to bring about a proper change management in the organisation it is required that the leadership should be proper and there should be a proper systematic flow of information from one point to another. Also there should not be any negative leaders which hamper the progress and instead there should be positive leaders which will help in the positive growth of the organisation. There needs to be more focus and attention should be given on the minute detail that is in the overall change management process. The selection of leaders in such an organisation will play a vital role in the overall process which will ensure the implementation of the change management process. Knowledge management will play a major role in the exchange of knowledge from the staff to the other workers and this will be taken care by the Training solutions network and solutions provider. The support of the senior management and the training provided in such a case is also very important and will lead to a better understanding between the other team members. Above all cadburys should be focussing on the following points that are mentioned below to tackle future c

Prohibition Led To The Rapid Growth Of Organized Crime Essay -- Americ

Prohibition was a period of time in which the sale, manufacture, or transport of alcoholic beverages became illegal. It started January 16, 1919 and continued to December 5, 1933. Although it was designed to put an end to all drinking, it simply created a large number of bootleggers who produced and sold illegal alcohol. Many of these bootleggers became very rich and influential through selling alcohol and also through other methods. They pioneered the practices of organized crime that are still used today. Thus, Prohibition led to the rapid growth of organized crime. The introduction of prohibition in 1919 created numerous opinions and issues in American society. Prohibition had been a long standing issue in America, with temperance organizations promoting it since the late eighteenth century. The movement grew tremendously during the nineteenth century. The Independent Order of Good Templars, one of the major temperance societies, increased it's membership by 350,000 between 1859 and 1869 (Behr 31). Other societies followed a similar trend, and millions of Americans belonged to temperance societies by the end of the nineteenth century. When the United States entered World War I in 1914, there was a shortage of grain due to the large demands to feed the soldiers. Since grain is one of the major components in alcohol, the temperance movement now had the war to fuel their fight. "The need to conserve grain, the importance of maintaining some semblance of discipline and devotion .... to demonstrate the nation's sober determination to protect its interests." (Repeal .. 1933) Thus, the war played a large part in the introduction of Prohibition. During the next five years many states enacted their own prohibition laws, and final... ...d crime, failed to be eliminated by the repeal. Although bootlegging became a thing of the past, other methods such as extortion, money laundering, and racketeering continued and became more prominent. "The bootleg wars ended with the relegalization of liquor, but the mobs did not fade away ... In one form or another, these mobs are still with us today." (Gingold 39) Prohibition led to organized crime as we know it today. Men like Al Capone got their start during Prohibition and were able to develop a system whose methods led into the Mafia and other forms of modern day crime. "Prohibition produced the like of Al Capone and organized crime, speak-easies, bootleggers, bathtub gin, and a national wildness called the "roaring twenties." (McGuire 1) Prohibition turned the small gangs that existed in the early twentieth century into the powerful Mafia that exists today.

Essay and Research Paper Essay

Some young children spend a great amount of their time practicing sports. Discuss the advantages and disadvantages of this. Use specific reasons and examples to support your answer. There is a true saying that everyone knows: playing sports is very good for our health. Playing sport helps us stay in shape, builds up our teamwork skill, and makes us consistent players. But there is a truth that not many people can realize: spending too much time on sports may cause some bad influences. Especially when it comes to young children. They need a balanced schedule so that they can take advantage and avoid some disadvantages of playing sports First, playing sports is necessary for everyone to reserve good health. It is proven by scientists that doing exercises or playing sports regularly helps people stay in a good shape, and helps avoid some health problems such as heart attack or blood pressure. For those reasons, young children should spend time in playing sport everyday. But if they spend too much time on that, they will not have enough time to participate in many other interesting and useful activities, such as going on a picnic with their friends or learning to play musical instruments†¦Even worse, they may not spend enough time on study. Second, playing sports helps young children develop their team-work skill. Usually when playing sport, they will be allocated into teams. By trying to connect with other team members to win to the game, they will learn how to get along with people, how to understand other people’s ideas, and how to coordinate with the others to get the best result, not only in sports, but also in study or in a working environment. But still, if they spend too much time on playing sports, there will be a disadvantage for young children, since they spend too much time hanging on with the others in a team, will not know how to handle problems alone, resulting in performing badly when working independently. Lastly, playing sports helps children learn how to stand up after failing, making them competitive in any tournament. It is definite that everyone will fail at least once when they play sport. The desire of being the winner urges them to try more and more. The more they try, the better.they become, but once they are so involved in the game, they somehow become so aggressive. Some will try anything to win, and some will even play unfairly to be the winner. The stories about the soccer players using drugs or the players fighting in a game are clear evidences to the disadvantage of playing sport when it is not under control.

Accordingly, significant work has been done on reservoir operation for known total irrigation demand and on the optimal allocation of water available to c rops at the farm level. Very few studies have been conducted to derive optimal reservoir operation policies integrating the reservoir operation with the on-farm utilisation of water by the various crops.This present paper deals with the development of model — Linear Programming (LP) — to be applied to real-time reservoir operation in an existing Chiller reservoir system in Madhya Pradesh, India. Keywords: Cropping pattern, Water resource management, Irrigation management, Optimization 1. Introduction In most developing countries, a huge share of the limited budget goes to creating facilities for irrigation. Construction of reservoirs requires very high investment and also causes socioeconomic and environmental issues.Water in the reservoir has multiple claimants and needs to be optimally utilized to generate maximum benefits through proper operation, which must remain consistent despite uncertain future inflows and demands. According to the World Commission on Dams, ma ny large storage projects worldwide are failing to produce the anticipated benefits (Labadie, 2004). Similarly, small storage projects made for local areas in developing countries, like India, are also failing to meet expectations.The main cause identified at various levels of discussion, as reported by Labadie (2004), is inadequate consideration of the more mundane operation and maintenance issues once the project is completed. For existing reservoirs, optimum operation is critical, since all the expected benefits are based on timely water releases to meet the stipulated demand. Real-time operation of a reservoir requires making relatively quick decisions regarding releases based on short-term information. Decisions are dependant on the storage in the reservoir and information available in the form of forecast hydrologic and meteorological parameters.This is especially important during floods and power generation, where the system has to respond to changes very quickly and may need to adapt rapidly (Mohan et al. 1991). For reservoir systems operated for irrigation scheduling, real-time operation is not very common because of longer decision steps. Traditionally, the reservoirs meant for irrigation purposes are operated on heuristics and certain rules derived from previous experiences. This defies the concept of water-management; much of the water is lost, which in turn leads to loss of revenue.In the early 1960s, mathematical programming techniques became popular for reservoir planning and operation; pertinent literature is available. An excellent review of the topic is given by Yeh (1985), followed by Labadie (2004) and Wurbs (1993). Along with simulation studies, Linear Programming (LP), Dynamic Programming (DP) and Non Linear Programming (NLP) are the most popular modelling techniques. A comparative study on the applicability and computational difficulties of these models is presented by Mujumdar and Narulkar (1993).Many of the aforementioned techniques ha ve been implemented in realistic scenarios, and many reservoir systems worldwide are operated based on the decision rules generated from these techniques. However, there exists a gap between theory and practice, and full implementation has not been achieved yet (Labadie, 2004). 1 14 & 15 February 2009 Kuching, Sarawak The basic difficulty a reservoir manager faces is to take a real-time optimum decision regarding releases according to the future demand and inflow. This leads to the problem of optimization of the stochastic domain.Two approaches of stochastic optimization are practised: i) Explicit Stochastic Optimization (ESO), which works on probabilistic descriptors of random inputs directly and ii) Implicit Stochastic Optimization (ISO), which is based on historical, generated or forecasted values of the inputs through the use of Time Series Analysis or other Probabilistic approaches. The ESO approach has computational difficulties; ISO methods are simple, but require an addition al forecasting model for real time operation. In the case of irrigation reservoirs, decision making at the reservoir level depends upon the water demand arising at the field level.In order to operate the reservoir in the best possible way, it becomes imperative to understand the processes occurring in the crop-soil-water-atmosphere system. This helps not only in the estimation of accurate demands, but also ensures optimum utilisation of water. If the processes at the field level are also modelled properly and integrated with the reservoir level model, the goal of water management can be achieved in the best possible way. Dudley et al. (1971) pioneered the integration of the systems in the determination of optimal irrigation timing under limited water supply using a Stochastic DP model.Dudley and his associates then improved the model (Dudley and Burt, 1973; Dudley, 1988; Dudley and Musgrave, 1993). Vedula and Mujumdar (1992, 1993) and Vedula and Nagesh Kumar (1996) have also contrib uted to this area. Their approach was to derive a steady state reservoir operation policy while maximizing the annual crop yield. DP-SDP and LP-SDP were used in the modelling. However, for real-time reservoir operation, Vedula and Nagesh Kumar (1996) stressed the need to forecast inflows and rainfall in the current season to implement the steady state operation policy.As a result, the ESO model has to be supplemented with an ISO model to get a policy for the current period. As an extension to the work of Vedula and Mujumdar (1992), a significant contribution to the real-time reservoir approach was presented by Mujumdar and Ramesh (1997). They addressed the issue of short term real-time reservoir operation by forecasting the inflow for the current period, a crop production state variable and a soil moisture state variable. Their work was based on SDP, but had all the limitations of SDP regarding the curse of dimensionality.Against this background, a model for the derivation of real-t ime optimal operating policy for a reservoir under a multiple crop scenario is proposed in the present study. The primary issue is that the reservoir gets inflows during the wet season (monsoon season) and is operated for irrigation in the dry season (non-monsoon season). The reservoir storage and the soil moisture level are considered to be the principal state variables, and the irrigation depths are the decision variables.An optimal allocation model is embedded in the integrated model to evaluate the irrigation water depth supplied to different crops whenever a competition for water exists amongst various crops. The model also serves as an irrigation-scheduling model because it specifies the amount of irrigation for any given fortnight. The impact on crop yield due to water deficits and the effect of soil moisture dynamics on crop water requirements are taken into account. Moreover, a root growth model is adopted to consider the effects of varying root depths on moisture transfer. The only stochastic element in the season is the evapotranspiration. The handling of stochasticity has been accomplished through dependability based forecasting in an ISO model. The rest of the variables, such as soil moisture status and the reservoir storage status, at the beginning of any period are considered to be state variables. The basic formulation is based on a LP model and is later transformed into a GA framework. 2. The Model Formulation and Concept The real-time operation model proposed in the present study integrates the reservoir level and a field level decision (Figure 3).It considers the soil-moisture status and the reservoir storage as the state variables and the applied irrigation depths as decision variables. The formulation is based on the conceptual model for soil moisture accounting and the reservoir storage continuity relationships. A major emphasis is laid on maintaining soil moisture in a state such that the evapotranspiration from the crops takes place at a rate that achieves better results in the form of increased yields from the crops. To assess the timing of irrigation water application, the soil moisture status of the crop is an important parameter.Whenever the soil moisture status approaches a critical limit, irrigation is applied. Thus, the soil moisture status is monitored either by physical measurement or through soil moisture models. Soil moisture models are more popular since they do not require a lot of instrumentation to be installed in the field. Soil moisture models can be formulated either by a physical approach (Fedders et al. , 1978) or a conceptual approach (Rao, 1987). The conceptual approach has been used by Rao et al. (1988), Rao et al. (1990) and 2 14th MANCO Hajilal et al. (1998) for the problem of irrigation scheduling.Vedula and Mujumdar (1992) utilised the conceptual model in their study. The same concept is adopted in the present study. Figure 3 Flow chart of real-time operation of reservoir 3 14 & 15 Februa ry 2009 Kuching, Sarawak 3. The Conceptual Model In the conceptual model for the Crop-Soil-Water-Atmosphere (CSWA) system, the basic assumption is that the soil acts as a reservoir, the main inputs to the reservoir are rainfall irrigation, and the main outputs are evapotranspiration, percolation and drainage. The extent of the reservoir is considered to be up to the effective root zone at the particular time.The soil water reservoir is governed by a continuity equation: ? ik +1 ED ik +1 ? ? ik ED ik ? IRR ik + AET i k = RF k (1) The conceptual model stated by Eq. 1 is used to compute the irrigation to be applied for the LP model with area as a decision variable. The following parameters are important for the conceptual model. Figure 1 shows the sketch for the conceptual reservoir. In the context of the conceptual model two parameters are important: IRRk RFk AETk EDk ?k Figure 1 Conceptual model Variation of Evapotranspiration with the Available Soil Moisture Evapotranspiration as a function of the available soil moisture is expressed as: kAETi k = PETi k if aai ? Zww (2) or AETi k = k aai PETi k Zww where AETi k (3) is the actual evapotranspiration that has occurred from crop i in fortnight k (mm), PETi k is the potential evapotranspiration in a particular geographical location (mm), Zww is the critical available moisture limit (mm/cm) = (Zf? Zw) d, Zf is the field capacity for the soil (mm/cm), Zw is the permanent wilting k point for the soil (mm/cm), d is the depletion factor and assumed to be 0. 5 in the present study, and a ai is the average available soil moisture over a fortnight (mm/cm). The average available soil moisture over a fortnight is given by ik + aik +1 a= 2. 0 k ai where otherwise aik = ? ik ? Zw if aik < Zww aik = Zww k +1 A similar expression can be used for ai . 4 14th MANCO Root Zone Depth Growth The root depth data in relation to the time stages are prepared according to the Linear Root Growth Model (adopted by Narulkar, 1995). The model assumes that maximum root depth is achieved at the start of the yield formation stage. It remains at the maximum depth until the maturity stage. A minimum depth of 15 cm is considered in the first fortnight to account for the conditions of bare soil and an area with sparse crops.The root depth model is shown in Figure 2. Life span of group Growth stages of group V F G Root Depth Max. Depth Figure 2 Root Depth growth model Relative Yield Ratio The yield of a crop is affected by water deficits and the rate of evapotranspiration. The rate of evapotranspiration tends to decrease depending on the available moisture content. There are many methods to model the phenomenon. However, the model used in the present study is the most commonly-adopted model. The relative yields are computed on the basis of the expression given by Doorenbos and Kassam (1979) YaiAETi k ? k? = 1 ? Ky ? 1 ? ? PET k ? ? Ymi i? ? (4) Equation (4) gives a yield ratio for a single period only. However, the aggregate ef fect of moisture deficits over all fortnights of crop growth is also evaluated. The final yield ratios computed for the crop during various time periods of a season is computed by a multiplicative model (Rao et al. , 1990). The determination of the yield ratio is very important since they reflect the operation policy for an irrigation system. The expression is given by ? AETi k Yai ncr ? = ? ?1 ? Ky k ? 1 ? ? PET k ? Ymi i =1 ? i ? (5)Water Requirements of the Crops The model derived for an optimal crop pattern uses predetermined irrigation demands. On the basis of this, the optimisation model selects an appropriate area for an individual crop. The irrigation demands are determined using the conceptual model stated in Eq. 1. The irrigation requirements may be calculated by substituting a value of critical soil moisture content instead of soil moisture in either of the fortnights k and k+1 and replacing the values of actual evapotranspiration by potential evapotranspiration and re arranging the terms of Eq. : ( ) IRRik = ? cr EDik +1 ? EDik + PETi k (6) 5 14 & 15 February 2009 Kuching, Sarawak where ? cr is the critical soil moisture content below which the actual evapotranspiration may fall below the potential rate. 4. Integrated LP Formulation In the objective function, the weighted sum of all the actual evapotranspiration values is maximised. The weights are assigned according to the yield response factors for individual crops in individual periods. The objective is to maximise the actual evpotranspiration rate to minimise the deficits in the yields.The available soil moisture in any time period in the objective function is indirectly maximised: ncr np ? a k + aik +1 ? Ky k MaxZ = ? ? ? i ? 2. 0 ? Zww i =1 k =1 ? (7) subject to the following constraints: 1. Soil moisture continuity ? aik + aik +1 ? PET = RF k ? 2. 0 ? Zww ? ? ik +1 EDik +1 ? ? ik EDik ? IRRik + ?

IRRik * AREAik = ? ID ? Ao RE k Eff (Maximum Reservoir Capacity M m3) (12) (13) Crop Simulation ModelThe optimisation model presented above yields some irrigation depth values that are based on forecasted values for the reference evapotranspiration. This reference evapotranspiration, in turn, is based on a dependability model. However, the actual evapotranspiration value differs from these values, and thus, before going into the next fortnight, the soil moisture status must be updated with the applied irrigation and actual climatic factors. The formulation for crop simulation is as follows: First compute the final soil moisture with the following relation ? ik = (? ik +1 EDik +1 + IRRik ?Fkcik APET k + ARF k ) / EDik If (14) ? ik +1 < 3. 1 ?k ?

Stochastic Analysis of Evapotranspiration It was previously stated that the data regarding the climatic factors is uncertain in nature and the determination of these factors beforehand is impossible. However, there is a general trend to assume the expected values for these factors and carry out the operation. The concept does not give a clear picture of the actual scenario and the appropriate weights for the individual growth stage of the crops are not assigned. The present study proposes a different method of forecasting the expected values for the climatic factors.The method of analysis starts with the co mputations of dependability values of reference evapotranspiration factors from the available data. The dependability of realisation of any stochastic variable is defined as the probability of equalling or exceeding that variable with a particular value. Mathematically, P(x ? X ) (18) where P (. ) is the probability and x is the variable under consideration and X is a stipulated value of the variable. A traditional method of estimation of the dependability value is the use of standard frequency formulae (e. . Wiebull’s formula or Hazen’s formula). In the present study, a detailed probability analysis for the data is performed. The data is fitted to a standard probability distribution and the best fitting distribution is tested through the Kolmogorov Smirnov Test (Haan, 1977). Once the values corresponding to different dependabilities are evaluated, dependability values for reference evapotranspiration are assumed to be different in different growth stages. The analysis is performed on the basis of the yield response factor.A high yield response factor signifies greater sensitivity towards the deficits, and thus, a higher level of dependability is assumed for the evapotranspiration data and a lower level of dependability is assumed for the rainfall data. This will ensure a higher value of irrigation required for the crop in the sensitive period. As a result, the crop will be safeguarded against any poor moisture content conditions. 7. LP Model Formulation for Optimal Cropping Pattern At the start of each dry season, depending on the storage volume in the reservoir, the crop pattern must be determined.To evaluate the crop pattern, another LP model is used. In this model, irrigation depths are calculated from Eq. (6). The formulation is as follows: The objective function is MaxZ = C1 X1+ C2 X2+ C3 X3 (19) which is subject to the following constraints: 1. Total available area X1+X2+X3? A (20) where X1, X2, and X3 are the decision variables related to the area of individual crops;C1, C2, and C3 are the cost coefficient for each crop in Indian Rupees (1 US $ = 50 INR); and A is the maximum area available for irrigation. 2.Area of each individual crop: 7 14 & 15 February 2009 Kuching, Sarawak The area under each crop is required to be constrained; thus, there are lower and upper bounds on the area under each crop. The lower bounds indicate the minimum area that can be allocated to a crop, while the upper bound indicates the maximum. In the present study, the lower bounds were defined for all the crops except cash crops, while the upper bounds were defined considering the present cropping pattern. The constraints can be expressed as Li? Xi? Mi (21) here Li corresponds to the lower bound of the area for the ith crop and Mi corresponds to the upper bound on the area of the ith crop. 8. Model Application The developed models were applied to the Chiller reservoir system in Madhya Pradesh, India (Latitude 23o23’ N and Longitude 7 6o18’ E). In the central part of India, many reservoir projects have been constructed for irrigation, but no irrigation is available from these reservoirs during the monsoon period (from June to September). The area receives about 90 to 95 % of its rainfall during the Monsoon season. The rainfall then becomes runoff to the reservoirs.These reservoirs are designed to contain the runoff in the monsoon season, but there is no runoff during non-monsoon months. The present formulations are specially suited for these types of reservoirs. Non-monsoon rainfall is rare and provides little runoff. A systematic data base was prepared for the various physical features of the reservoirs, including the meteorological and hydrological data such as evapotransiration, details of crops in the command area, details of net returns from individual crops and soil properties collected from the College of Agriculture, Indore, India. . Results and Discussion Optimum Crop Pattern A separate computer p rogram was run before the real time operation program to determine the optimum crop pattern for all possible storage values. The results of the optimum crop pattern are stated in Table 1. The results indicate that from a storage level of 31. 10 M m3 to a storage level of 26. 06 M m3, the cropping pattern is same as the one that has been adopted in the project formulation. However, below a storage level of 26. 06 M m3, the crop pattern changes suddenly, and wheat (ordinary) is not recommended by the model.The area of wheat (hybrid) also gets reduced when the rainfall storage is below this level. However, the area for Gram is full, up to a storage level of 15. 83 M m3. The change in cropping pattern indicates that efficient water usage is maintained.

The model also yields the values of irrigation to be applied to individual crops in the fields. In the wake of deficient water supplies, the model distributes the available water over the time for different crops optimally. The sample results of the present model are stated in Table 2.The available moisture to the crops is not affected, and generally the soil remains at the upper limit of the available soil-moisture. This 8 14th MANCO is because the crop pattern is predicted according to the availability of the storage in the reservoir. The results are indicative of successful application of the real-time operation strategy proposed in the present work.

Furthermore, the models ensure an optimum reservoir release over different time periods.In addition, they also ensure optimum allocation of the available water over the different crops in the fields. While allocating the water to different crops in the fields, the model takes into account the critical growth stages of the crops and allocate s sufficient water to each crop to safeguard it against any ill effects of water deficits. The optimum crop pattern model used in the study will only allow productive irrigation, so the amount of wasted water is reduced.
