Abstract

Regarding the importance of instantaneous peak DISCHARGE estimation for watershed management study, in this research make an effort to make link between constant parameters (geomorphologic) and variable (hydrologic) to present MODELs with minimum dependence on climatic and hydrologic data in hydrologic estimation. So, with using of synthetic unit HYDROGRAPH at DRAINAGE BASIN of Kan (Soleghan River) and to compare these results with recorded peak DISCHARGE in outlet of watershed, the best MODEL can be derived. So, comparison of study MODELs from relative mean error (RME) and root of mean square error (RMSE) in study DRAINAGE BASIN located in central Alborz watershed shows RME for GIUH MODEL is 17.99, RMSE is 15.46 for Snyder RME is 59.66, RMSE is 26.83, SCS and Triangular MODELs have the best estimation, respectively. Regarding to lack of recorded instantaneous peak DISCHARGE in Kan DRAINAGE BASIN’s hydrometric station (11 events), we can’t drive instantaneous peak DISCHARGE MODEL. For this reason, with using of factors in each of studied MODELs, other effective factors and 82 recorded events of daily peak DISCHARGE, daily peak DISCHARGE MODEL derived. So the purpose of this study is presentation regional MODEL for peak DISCHARGE estimation. For this purpose from GIUH, Synyder, SCS and Triangular MODELs factors and other effective factors used.
