Abstract

The Instantaneous Unit Hydrograph {IUH) concept is widely applied in the simulation of the rainfall-runof process. in this paper a new GEOMORPHOLOGIC UNIT HYDROGRAPH, based on the concept of cascade linear reservoirs has been developed and analyzed. This method represents the watershed as a cascade of reservoirs across the watershed main channel.The two most important characteristics of the model are: (a) it explicitly includes the watershed morphology in its formulat ion and (b) it depends on only one uncertain parameter which must be estimated. The result of the model. has been compared with Nash’s black box model with one more parameter. The study area was the AMMAMEH WATERSHED southern of central Alborz mountain chain in Iran. The results showed the efficiency of this model to simulate the rainfall-runoff process using the watershed geomorphologic properties. GIS tools in the current modeling allow the accurate and easy determination of the geomorphologic characteristics of the model.
