Abstract

 

Due to the importance of instantaneous peak discharge estimation for watershed management study in countries like Iran, the search is ongoing to correlate geomorphologic and hydrologic parameters to present models. This paper describes the use of synthetic unit hydrograph at drainage basin of Mehran (Joestan River). The obtained results were compared with recorded peak discharge in outlet of watershed. The models of Relative Mean Error (RME) and Root of Mean Square Error (RMSE) in drainage basin in central Alborz watershed were compared with each other. The results indicate the RMEs of 20.43, 40.06, 133.082, and 135.72, and RMSEs of 16.08, 14.65, 25.37 and 25.82 for GIUH, Snyder, SCS and Triangular models respectively. The daily peak discharge model was derived by 177 recorded events of daily peak discharge.

 

Key words: Peak discharge, parameter, model, Mehran Basin.
