Construction of Storage-Performance-Yield Relationships for a Reservoir Using Stochastic Simulation

TLDR: In this paper, separate contours of reservoir performance, including reliability and vulnerability, were developed on the storage-yield plane, using stochastic reservoir sim ulation, which gave rise to the storageperformance-Yield (S-P-Y) relationships, the construction of which was illustrated in a case example.

Abstract: In the past, many researchers have used stochastic streamflow models along with sequent peak algorithm or sim ulation to obtain storage-reliability-yield (S-R-Y) relationships for a reservoir. These S-R-Y relationships con sider only the probability of failure, but not the likely consequences of the failure (vulnerability). In this paper, separate contours of reservoir performance, n amely reliability and vulnerability (eventbased), have been developed on the storage-yield plane, using stochastic reservoir sim ulation. These contours of performance, when superposed, give rise to the storageperformance-yield (S-P-Y) relationships, the construction of which is illustrated in this paper through a case example. These relationships provide more com prehensive information to the reservoir planner regarding perform ance than the S-R-Y relationships.
