Simulation Rainfall-Runoff Processes and Water Balance Component in Rivers Basin (A Case Study: Korkorsar River Basin)

The process of precipitation-runoff of each basin, is mostly influenced byhydrologic, geomorphology conditions and zone climate. The measurement, distributionand pattern of precipitation, canopy cover, snow melt and accumulation processcharacteristics, soil layer characteristics and geology formation are the most importantfactors which impact the runoff measurement and basin water balance components. Oneof the general procedures for acknowledgement of precipitation-runoff process is itssimulation by using the hydrologic models and analysis of the results. In this study, itwas tried by using BROOK90, the basin process of precipitation-runoff, snowaccumulation and melt model and also the basin water balance components ofKorkorsar are simulated and calibrated then the effect of hydrologic conditions and alsoclimate changes on basin precipitation-runoff process and water balance components arestudied and analyzed.
