Abstract:
floods are a primary problem in many countries, especially in underdeveloped countries such as Sudan. Dams are generally constructed to regulate the flow and counteract expected floods. Various many studies have been conducted to evaluate floods and their impact on the environment and constructed dams. Dams may be benefited but sometimes they may affect the natural surroundings negatively. Remote sensing is a technique that enables researchers to obtain information easily, rapidly, and cheaply, over vast areas. Rappid developments in computer technology, in both hardware and software, and the geographical information systems (GIS) made it possible to process Remote Sensing data and convert that data into spatial format of maps. The information derived from Remote Sensing techniques and other data from other techniques provide a light potential for the identification, monitoring and assessment of floods. This study aims at studying the effect of dams constructed in same water channels within the study area of Omdurman locality. The main conclusion with an area of approximately 8200 Km reached is that the constructed dams decreased the possibility of flooding the study area by the Nile waters.
