Distribution and verification of Quaternary deposits in the Cairo Area
AbstractIn previous research studies, the combined impact of the morphology of the surface, the River Nile and its changes, and the geological, environmental and historical development in the Cairo area, were considered. As a result, characteristic regions of soil formations were identified and classified by their origin, and their distribution produced on maps.In present research work, the authors have examined a large number of borehole records to verify the previous Classification. These boring records were simplified and subsoil section drawn at different locations.It was found that the simplified borehole records and subsoil sections are in complete agreement with the distribution of soils based on their origin. Thus, typical profiles representing classified types in Cairo area could be drawn and related to the stratigraphical sequence.In order to fully appreciate the nature of alluvial and deltaic deposits in the Cairo area, important physical and mechanical properties of each sublayer of the defined soil formations were determined. This was done on the basis of soil mechanics test results of natural samples.
