Through the current research, a systematic methodology, for estimating flood hazard and risk maps, based on a geographic approach using Geographical Information System (GIS) and Remote Sensing (RS), has been developed. It concludes that GIS and modern ground surveying techniques are a valuable tool as they are capable of integrating all the other techniques of flood risk assessment. The research results can help developers, planners and engineers for flood management and land use planning in many fields, such as:
 Calculate the amount of water resulting from the storm.
 Guide in risk and its level associated with a particular hazard at areas under investigation.
 Calculate the storage capacity of water to determine the level of mitigative structures of the proposed dams in a better position for protection with the help of GIS (disaster managers).
However, in the current research, one Complete- Hydraulic Model is presented, namely: Interactive-GIS Based Model.
