Sediment Management by Multi-objective Operation of Sefidrud Dam with Respect to Hydropower Generation and Environmental Issues

Traditional management of water resources, which is often based on cost and benefit, is not sustainable approach; therefore reassessment of the former approaches seems necessary nowadays. Optimum reservoirs operation is one of the important water resource management problems. Present study has used the non dominated sorting genetic algorithm (NSGA-II) for multi-objective optimization of Sefidrud reservoir in North of Iran. The main goal of the study is to reach sustainable operation of the reservoir by considering these objectives simultaneously: supply of downstream demand, sediment evacuation and hydropower generation
