The current study aimed to simulate the rainfall–runoff events in two catchments (Daraja and Al-Ghar) of Palestine using HEC-HMS model during 1990‒2010 data period. Main inputs to the model included soil properties, land use land cover, stream network, slope in addition to rainfall data, and physical catchment characteristics. The model was calibrated and validated on total of 20 rainfall–runoff events from both catchments. Model efficiency was estimated through accuracy percentage, Nash–Sutcliffe (NS), and coefficient of determination (R2). Simulation indicated acceptable model efficiency with NS (R2) value ranged between 0.78‒0.96 (0.79‒0.98) and 0.88‒0.94 (0.91‒0.98) for Daraja and Al-Ghar catchments, respectively, over entire data period. Outcomes of the study suggested that HEC-HMS model calibrated during this study may be used for forecasting the flows on short time-step with future climatic scenario in the similar environments and may be helpful for water resources manager to predict and mitigate the flood risk.
