Abstract: A deterministic conceptual rainfall-runoff model has been developed; the model simulates streamflow hydrograph in an event basis. The model has eight parameters all of which required to be evaluated using optimization technique. The major input requirements for this model are hourly rainfall, hourly potential evaporation and the average daily streamflow record. The model is calibrated and tested using the available data collected from only one semi-arid ephemeral catchment located at the central part of Jordan. Shuffle Complex Evolution (SCE. UA) optimization method developed by Duan et al, (1992) is employed to optimize the parameters of the proposed model. The performance of the model was evaluated using the goodness of fit measures. The simulation results obtained show that the proposed model has a good match between observed and simulated streamflow for both optimization and validation stages. The simulation results indicate that the model performs well, and hence the model w i l l be use fu l in des ign of hyd rau l ic s t ructu res and in ef fect ive managemen t of water resources at arid and sem i-arid catchmen ts.
