Multiobjective Optimization Model for Water Allocation in the Aral Sea Basin

By Daene C. Mckinney and Ximing Cai


Current conditions of political and economic development in the Central Asian Republics of Uzbekistan, Kazakstan, Kyrgizstan, Tadjikistan, and Turkmenestan require new systems of analyzing water management. A water allocation model for the Aral Sea basin based on multiobjective optimization and water balance principles is being developed which can be used to evaluate the efficiency and sustainability of water use in the region. The model will be a decision aid for water distribution planning and an instrument that will be sustainable by and useful to local specialists. The first step has been the construction of a multiobjective model to investigate annual allocations of water in the Amudarya River basin. The objectives considered in the model include maximizing the flow to the Aral Sea, maximizing the satisfaction of demands for water in the basin, and equalizing the distribution of water deficits in the basin
