Abstract
The paper develops a new methodology and RESOOSE model for optimizing
operation of multiple reservoirs considering sediment evacuation for multiple objectives
consisting of maximization of irrigation, hydropower, storage conservation and minimization
of flood damages. The optimization and sediment evacuation modules of the model are based
on Genetic Algorithm and Tsinghua equation respectively. According to the criteria developed
for selection of reservoirs, three reservoirs on Indus River of Pakistan have been selected. The
model has been calibrated and validated for Tarbela and Chashma Reservoirs. The calibrated
model has been applied to Diamer Basha (proposed) and Tarbela Reservoirs. Eight scenarios
comprising of combined and individual objectives were developed. The optimized results of
different scenarios have been compared with existing rule curves. The optimization results
reveal that objective function for hydropower, irrigation, and storage conservation benefits
would be enhanced by 11, 13 and 84 % respectively while flood damages would reduce by
80 %. Similarly the optimized rule curves will increase the benefits up to 579, 960, 533 and
648 million US$ per year (on 2012 prices) for all the four components respectively. The
maximum value of US$ 977 million per year has been found for the scenario 5 which gives
equal priority weight to all the four sectors. The developed model can be applied to other two
reservoirs (in series) for optimization of rule curves
