Floods hazards assessment by integrating hydrologic modeling and a geographic information systems : multi-criteria decision technique

Abstract EN

The protection of urban areas located on the eastern side of the Nile River in Upper Egypt, which is highly exposed to flood hazards, represents one of the most important priorities of the Egyptian state to achieve the future of sustainable urban development for Egypt's Vision 2030.

This research deals with two main steps: The first step is to combine a hydrological model (HEC-1) with a geographic information system )GIS) to obtain high-caliber hydrological modeling.

The second step is to create a flood hazard map by GIS- Model Builder based on the multi-criteria decision analysis method in geographic information systems (GIS-MCDA) based on the application of the Analytic Hierarchy Process (AHP).

The research flagged out that the obtained results would most probably assist decision-makers Creating a clear vision for sustainable development in the region.

In addition to that, the research highlighted the importance of implementing flood hazards management activities to ensure the environmental rehabilitation of watersheds to avoid flood disasters.
