Résumé partiel
Runoff estimation is very important for water resources planning and management. Hydrological modeling is inevitable for accurate and precise estimation of runoff from a watershed. A major problem in the hydrological modeling is the inadequate field measured data to describe the hydrologic processes.With unavailability or limited availability of data, the quantitative understanding and prediction of the runoff generation processes and its transmission to the watershed outlet remains one of the most challenging area of hydrology. The use of remote sensing and GIS, in combination with semi distributed hydrological model provides new possibilities for deriving spatially distributed time series of input variables, as well as new means for calibration and validation of the hydrological model. In the present study, the HEC-HMS model is applied to the Hadaf river watershed, which is predominant with agricultural land and falls under semi-arid zone, where water resources planning and management is necessary for irrigation scheduling, water harvesting, flood control, drought mitigation and design of various engineering structures. In this study four different events of meteorological & discharge data, DEM, LISS-III and LISS-IV remote sensing imagery, soil maps are applied as inputs for HEC-HMS models
