GEOMORPHOLOGICAL HAZARD MAP ALONG SOUTHWESTERN SINAI COAST EL-TUR AREA USING GIS

Summary/Abstract: This study discusses some problems of current geomorphic disaster mitigation. Starting from the geomophological hazard assessment which is an important component of natural hazard risk assessment, we should evaluate and mitigate these hazards, remote sensing, topographic and cadastral maps, data of rainfall, floods and other data sources which have been used under a GIS environment and manipulated. The aim of this paper is to define geomorphological hazards, in the south of Sinai district, which represents one of the main drainage basin systems in Egypt, this district being the subject of flashing floods almost every year, especially in spring and autumn. In recent years there has been a pace of increased flooding that caused significant damage to infrastructure and other facilities in the region. In this study, a new framework which integrates the Geographic Information System (GIS) with the Watershed Modeling System (WMS) for flood modeling is developed. It also interconnects the terrain models and the GIS software, with commercial standard hydrological and hydraulic models, an operative model is applied for the definition of possible risk scenarios. This model is founded on an inventory and the quantification of geomorphological hazards and tourist vulnerability, in comparison with trail rescue data. The model can be applied to other environments and tourist areas.
