الملخص

In the last few years devastating flash floods descending downstream through valleys have occurred in East Nile Locality-Sudan. A flash flood can be caused by intense rain, particularly when it takes place in a saturated area where rain has previously fallen. Under these conditions the additional rain runs off over the surface and accumulates in streams and channels at a much accelerated pace. Runoff is the one of the components consists of water cycle and useful water resources to stand human life. The aim of this research is to estimate analysis and predict the runoff to make stable water use and flood control by water harvesting projects. Soba Valley (East Nile Locality-Sudan) has been selected as study area. To achieve this aim the various raster and feature class data had been used for computing Hydrologic parameters. For estimating runoff, Soil Conservation Service method had been adopted to calculating water Transformation and losses and Muskingum method has been chosen to calculateflood routing. The runoff model had been created and the annual runoff for streams has been calculated. The simulated runoff values can be used for flood control and flood damage estimation studies in the future.Then dam’s location had been selected to minimization flash flood risk according to runoff volume, soil type and topography. A model builder had been designed to repeat the steps of the processes and analysis automatically in a quick manner to save time for the study of any other similar areas. General impact for selected dam on residential and agricultural areas had been identified to compare the proposed dams’alternatives
