Problem statement: In present study the KINFIL model was used for the catchment management, including the investigation of deforestation on predict flood runoff assessment with a significant precision. Approach: The KINFIL rainfall-runoff model has been used for the reconstruction of the rainfall runoff events in agricultural land use. The implementation of the KINFIL model supported by GIS proved to be a proper method for the flood runoff assessment on Sepidroud catchments (north of Iran), during which different scenarios of the rainfall events. Results: The results show when the observed discharge peak was 2.25 m3 sec-1, the computed discharge by the KINFIL model predicted 2.4 m3 sec-1 (about 7% errors) and when the observed discharge peak was 1.9 m3 sec-1, the computed discharge by the KINFIL model predicted 1.8 m3 sec-1 (about 5% errors). Also, the results showed when deforestation reaches 10% of total primitive areas in Sepidroud basin; the runoff-peak may increase more than 14.5 times. Conclusion/Recommendations: It can be stated that utilizing KINFIL model for determining the peak of discharge in agricultural land use, is a hydrological model, which has the good convergence with observed data.
