The advantages of this model is determination of the first tank parameter using infiltration capacity. This parameter was directly determined based on infiltration measurement for the respective land use zone. The application of this model was utilized for revising the discharge data since several period of the recorded data were not accurate. Key Words: rainJali run offmodel, tank model, infiltration
