7.3-A model on reservoir to reservoir routing and estimation of net discharge from reservoirs

Abstract

A series of n-linear reservoirs with different storage co-efficients Cl 's>, at different positions in a mountainous area have been considered and a mathematical expression of run-off model has been presented in the paper. The inflow of water into the particular reservoir is considered as an outflow of water from the preceeding reservoir <situated at higher altitude> as well ass the contribution of the rainfall excess (Re) over the reservoir.The net discharge over the area is calculated from the discharge of the nth. reservoir (situated at lowest altitude>, after considering outflows of all the reservoirs at different positions within the area. The procedures for finding out the storage co-efficients and the rainfall excesses with infiltrations of all the reservoirs within the area have also been presented in the paper.
