Part of: North American Water and Environment Congress & Destructive Water

Abstract:

In the present study, a detailed multiobjective nonlinear programming model is formulated and applied to a multireservoir system at upper reaches of Krishna river basin in Karnataka State, India. The model has been solved using GAMS/ MINOS for maximization of releases for the two objectives, namely with irrigation as the first priority and power as the second, for a four reservoir system. The results were obtained for 37 years of historical monthly flow data. Using these results, plots of individual storage Vs total storage in the system, and total release Vs storage of individual reservoir were plotted for each reservoir system. From these plots of optimization results, the release-rules and storage- allocation functions are derived.
