Methodology for Water Balance in Hemren Reservoir

Abstract

The water balance is considered as an important subject in the present time which has a great role in estimation of the quantity of water entering a dam. In this paper approach to estimate the water balance in Hemren dam, an equation has been found to calculate the discharge entering to Hemren dam through relate the variables (Qout from Derbendi-Khan, Qin to Hemren reservoir and rainfall intensity falling on the intermediate catchment area between Hemren-Derbendi- Khan dams) by using the regression analysis. The data were collected for theinterval from 1980 to 2004. The equation gives a correlation oefficient 0.956 for the relation between the observed and calculated discharges.
