derivation of conflict resolution rule-curves in multi-purpose multi-reservoirsystem for inter-basin water transfer during drought

Allocation is the number-one cause of conflictin water resources, whether between sovereign nations, different user groups orneighboringbasins. the inter-basin water transfer is a remedy to the negative issues of water shortage in drought-strickenregions. in a water transfer project,the receiving basin always benefits whilethe donorbasin may suffer. in this work, to define an operating policy, a multi-reservoir multi-purpose system issimulatedand optimized for a set of long-term historical records. a multi-objective optimization model is developed based on non-dominated sorting genetic algorithm(nsga-ii). the optimization results define the best possible performance set foratwo-basinsystem with the objectives of suppliedwater shortage minimization during droughts.ina multi-objective optimization problem, there isnot a single solution that simultaneously optimizes allobjectives. however,decision makers are concerned with finding a unique compromise solution that balances conflicting objectives in a socially acceptable manner. the game theory can identify and interpret the behaviors of parties inwater resource problems and describe interactions of different parties who give priority to their ownobjectives, rather than system’s objective. using the strategicformdescription for differentmoves or actions available in the optimum trade-off front, nash equilibrium outcomes predicted by game theory narrowthe results suggested by optimizationmethod. in this study, the inter-basin water transfer project from zohreh multi-reservoir multi-purposesystem in southwesterniran to the persian gulf coastal districtis investigated using the proposed methodology.
