Abstract: 

Among the main objectives in hydrology are to forecast quantitatively the process of rainfall-runoff, and to determine flood discharge at the outlet of a watershed. Flood discharge can be estimated using rainfall-runoff models which explain hydrological phenomena for unmeasured watersheds. Relationship between hydrology and geomorphologic parameters can lead to the estimate of hydrologic response of a basin. The purpose of this study is to investigate the consistency, accuracy and reliability of geomorphologic model (GIUH) in estimating the shape and discharge of flood resulting from a rainfall with certain intensity and duration. The results of this model were compared with SCS (Soil Conservation Service), Snyder, triangular, Rosso and Geomorphoclimatic (GCIUH) unit hydrographs. The results showed that in Kasilian basin with the area of 67/78 km2, GIUH model had the least amounts of main relativity (MRE) and square error (MSE). Furthermore the result showed that the efficiency of geomorphologic model ratio to Snyder, SCS, Triangle, Rosso and GCIUH in Kasilian Basin are 91.06, 99.11, 88.642, 48.19 and 4.94 respectively. Therefore the result of Geomorphologic model compared to other models (based on this study) is the most efficient model to estimate flood discharge.
