Abstract

A watershed is considered as a system consisting of different interrelated hydrologic units that reacts to rainfall. Since dimensions of runoff hydrograph are quantitative indices that represent the basin's reaction to rainfall, therefore recognizing the relation between rainfall and runoff is of high importance in hydrology. To investigate the effectiveness of CLARK, NASH, Snyder, SCS, Triangular and Santa Barbara unit hydrographs in estimating runoff hydrograph, four basins namely; Kasilian, Kasilian- Shirgah, Gharan Talar, and Talar with areas of 67.78,341,403, and 1772 km2respectively, were chosen in north of Iran. In these basins, 10 pairs of rainfall- runoff events were chosen and the runoff hydrograph of each basin was assessed. A comparison of the estimated hydrographs of studied models with observed hydrographs showed that in Kasilian basin, Santa Barbara model had the least amounts of mean relative and square error. In Kasilian-shirgah and Gharan Talar basins, Snyder model had the least amounts of mean relative and square error. In Talar basin, the Triangular model had the least mean relative error while, Santa Barbara model had the least amount of square error.
