Abstract: Abstract Ras Gharib area received heavy rainfall during October 26–27, 2016. This abnormal quantity of rainfall led to flash flooding in the area and consequentially to death of tens of people as well as damage to infrastructures and properties. The Advanced Spaceborne Thermal Emission and Reflection Radiometer Global Digital Elevation Model V002 are used with data resolution 30 m. Data of Tropical Rainfall Measuring Mission detected that precipitation near Ras Gharib was about 10 mm/day. Hydrological and surface analyses are generated using GIS tools. Some important morphometric analyses are calculated for basins description. The intensity and distribution of flood destruction in the study area were controlled by the geologic, geomorphologic characteristics of the study area. Also, huge amount of precipitation in short time and uncontrolled and unplanned development increase the impact of the flood. The results indicate the presence of two basins in the study area characterized by the possibility of flooding. Accordingly, establishing flood channel, of about 38 km long, is vital to protect the city from flood hazards in the future.
