Hazard Assessment of the New Cairo City, Egypt, Using Remote Sensing and GIS Techniques

Abstract

Applying remote sensing and geographic information system (GIS) techniques enables detailed study and geological hazard assessment of the New Cairo City. A model for evaluation of geological hazards and urbanization assessment is constructed as final output of the present work. This model presents a classification of the study area into five zones according to suitability for construction. The first zone represents extremely hazardous surfaces, prone to flash flood, with highly fractured and faulted grounds and bad engineering properties of their substratum. These surfaces are located in the southeastern and northeastern corners of the study area. The fifth and last zone represents the least hazardous (safest) surfaces, with negligible flash flood hazards, few fractures and faults and fairly good engineering properties of their substratum. This zone is represented in two small surfaces found in the middle of the study area. The second, third and fourth zones have intermediate properties as regard to safety for construction.
