| Abstract | for careful and articulate planning as operation of most multiple reservoir systems reflects the existence of sometimes conflicting, sometimes complementary multiple purposes served by reservoir storage capacity and the water stored and released from reservoirs. Besides this, recently there has been world wide awakening to the negative consequences of large water resources projects which further calls for more rigorous consideration of social, political, and environmental aspects along with economic considerations in design and planning of any water resources projects. In this study all these aspects are given due considerations in planning and management of the water resources of a basin in an integrated manner. A practical procedure has been developed for the analysis of multiple objective, multiple facility reservoir system to develop trade-offs guide lines between conflicting objectives. The multiobjective analysis involves generation of a set of noninferior operational alternative plans with the trade-off estimation among alternatives via simulation and then selection of the best preferred alternative plan based on the decision maker(s) preferences. A simulation model based on network flow theory have been developed to analyze the reservoir system in Narmada River Basin under different operational strategies. Reliability based performance indices were employed to adequately evaluate the performance of the system under various alternative operational strategies. Thus generated alternative plans were used in deriving the interrelationship between the two most important purposes (irrigation and firm energy generation) of reservoir operation and management in the basin. The concept of reliability has been incorporated in such tradeoffs analysis. The selection of the 'best' alternative operational plan has been achieved through a multicriteria analysis in which five main criteria; firm energy generation, irrigation potential, performance indices, environmental impact and social impact indicators have been considered. The assumption made was that all the projects in the Narmada River Basin are going to be built, as has been started by the Indian government. Eigenvector approach has been used to elicit the subjective preferences of the criteria from a group of ad-hoc decision makers. The reservoir operating policies in the form of standard operating rules were established for each reservoir in the system by proposed method of piecewise regression. To ensure the beneficial use of obtained releases for irrigation it is essential to adjust the cropping pattern with respect to possible releases available. The decision problems like crop area planning also involves multiple, conflicting and non-commensurable criteria and a "satisficing" decision is needed. Such real world decision problems can rarely be defined precisely in mathematical terms rather than in terms of the real world which may often be unprecise by nature (because offuzzyness). To incorporate fuzzyness in crop planning model, a simple yet potential tool in fuzzy multiobjective analysis has been explored and utilized. The model addressed the issue of establishment of most appropriate cropping pattern in the command area in view of the surface water availability through optimal operation of the reservoir system in the form of available optimal releases and multiple conflicting and non-commensurable objectives framework which is usually involved in irrigation planning. Therefore, the purpose of the developed model is to determine the type of crops to be grown, their extent and the level of water application such that all other available resources are efficiently utilized so as to result in a most satisfactory decision to the multifaceted, conflicting, non-commensurable and imprecise objectives. |
