Mapping flood hazards by multi-criteria decision analysis technique in geographic information system (GIS-MCDA)‎

Abstract EN

In terms of the importance of constructing new mega-urban zones to achieve future sustainable urban development for Egypt's vision 2030, this research was initiated with the objective of protecting such zones by mapping flood hazards by “multi-criteria decision analysis” based on “geographic information system” (GIS-MCDA), where the Hegaza village-Qena governorate in upper Egypt was taken as a study area.

accordingly, a research methodology was planned to encompass five investigations (theoretical, field, numerical, analytical and inferential investigations).

the hydrology of the study area was modeled by blending Gis model-builder and the hydrological model (HEC-1).

a flood hazard map (F.H.M) was produced based on (GIS-MCDA), in terms of the analytic hierarchy process (AHP).

the research flagged out that the obtained results would most probably assist decision-makers.

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