Abstract:
The rapidly increasing demand for water, coupled with its comparatively limited supply, is a serious problem in most parts of Iran. In spite of this fact, the economic efficiency of the allocation and use of this scarce resource has seldom been examined. The present study aims to investigate this problem and suggest guidelines for efficient man~gement of water resources. After an economic appraisal of the institutional and legal framework within which the allocation and use of water in the country takes place, the study concentrates on the question of efficient allocation and use of water in Tehran and the surrounding agricultural regions. Using mathematical programming, a detailed model for determining the optimum allocation and use of different sources of water in the Varamin region for the purpose of irrigation is developed. In this model a number of important but usually neglected issues involved in the regional management of water resources are examined. Since this region, along with the Karaj agricultural region, competes for the available surface water with Tehran, an inter-regional optimisation model for the allocation of water resources for the purpose of irrigation subject to a given urban reqUirement is then developed. This model demonstrates the potential economic gains which could be achieved through an integrated inter-regional approach to the allocation of water.Efficient management of water supply, both in the short and long run, requires an accurate picture of the behaviour of demand. Using econometric techniques, a demand model for urban water is estimated. Among the determinants of demand, price (water rate) is found to be important. Expressions for demand as a function of price in future years are obtained, using forecasts for other explanatory variables such as population and income. Finally, the projected demand functions (1976-85) obtained above are incorporated in the objective function of a chance constrained multi-reservoir multi-region programming model which optimises the allocation of water resources on the basis of opportunity cost rather than a prespecified 'requirement' approach. This model also considers the stochastic nature of water flows and looks at operating policies for the reservoirs which would provide a more reliable supply than the current practice.
