Abstract
In hydrology/Water resources, normally rainfall data are available for longer periods than runoff data. Many attempts have been made to extend these runoff data by using system approach and conceptual models. The conceptual approach to simulate runoff at the outlet ofa catchment is based on the physical processes involved in the transformation of rainfall into runoff (river flow). In this paper a conceptual model, (SEAMOD) has been used. This model has a limited number of parameters to optimize when compared to other models like the sacramental model. Also it requires less input data. The model assumes that the storage is divided into three layers, the surface storage, subsurface storage in the unsaturated zone and subsurface stoppage in the saturated zone. The results showed that the model under estimated the low flows from the catchment, but when the storage were lumped together, ir underestimated the high flows (peaks). Graphical comparison of the calculated and observed discharge showed that the model fits the data very well.
