It overlooks the Nile valley at the site of Cairo. Mokattam high plateau rises above the flood plain of the Nile valley by about 180 meters. Geologically, it belongs to Eocene time and it is mainly covered by thick succession of limestone with thinner beds of shale and marl. Mokattam high plateau suffered occasional landslides at different locations. Frequent rock falls were observed along the southern edge of the plateau. The most significant was an edge failure that occurred in front of a five-storey hotel. The rock mass that slipped reached the edge of this hotel and left the footing of the corner column almost overhanging. Since then the problem was subject to various studies by several workers who attributed the problem to several causes including geological, morphological, physical and human factors. In this present work, thorough investigation and analysis of the problem have been made in order to assess the potential hazards due to rock fall and its causes. The study indicated that the problem occurred due to variety or combination of causes including geological, morphological, physical and human. However, the triggering factor was water infiltration due to rainfall and human activities. Geological and morphological conditions lead to the susceptibility to rock fall caused by water infiltration. Limestone in the area is primarily porous and highly jointed, thus allowing penetration of water that descend and occur on underlying plain. Infiltration and run off of water into cavities due to human activities such as car wash at a near by petrol station provided continuous supply of water over a long time period. Furthermore, although the region is arid, intense rainfall frequently occurs. Well-documented studies have revealed a close relationships between rainfall and activation of rock fall. The study included assessment of present geomorphological and geological characteristics, including faults and fissures at the study area, identification of man made activities and water infiltration and analysis using a cross- sections passing by the hotel and the underlying layers and finally recommendation of economically feasible control measures for the problem.  Conference Name : 2nd International Conference on Geotechnical Site Characterization (ISC-2), Porto, Portugal , 2004: 1081-1887.  Publishing Year : 1426 AH 2005 AD  Article Type : Article  Conference Place : Porto, Portugal  Organizing Body : International society of Geotechnical Engineering  Added Date : Wednesday, March 30, 2011  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email محمد عبدالقادر الصهبى El- Sohby, Mohamed Abdelkader Investigator Doctorate msohby@hotmail.com محمود إبراهيم أبوشوك Aboushook, Mahmoud Ibrahim Researcher Doctorate profdraboushook@gmail.com سعيد أسامه مازن Mazen, said Osama Researcher Doctorate Mazen_62@Yahoo.com Files File Name Type Description  29414.pdf pdf Slope degradation and analysis of Mokattam plateau, Egypt Back To Researches Page
