The Flash Floods hazards in The Shaik El-Shazly region in The Eastern Desert, Egypt " A Geomorphological study using GIS"

Abstract

The Shaik El-Shazly region, a study area, is frequently exposed to flood hazards due to four drainage basins that are the primary sources of the Wadi Al-Sheikh basin, a major stream in the Wadi al-Khirit basin, which ends east of Kom-Ambu. The four drainages basin namely Umm Hirenah, Umm Samrah, Umm Sreha and Umm Dehesi, which all meet in the Shaik El-Shazly area and poses a natural hazard. The area has been exposed to multiple flash floods due to geological, surface topographic, and climatic factors. The most recent event was the 14 November 2021 flash flood, which caused the village of Shaik El-Shazly to drown and partially collapse the outer wall of Sidi Abu Hassan al-Shazly's mosque and warehouse due to runoff from Wadi Umm Samrah. The study determined the level of flash flood danger in four basins, with Umm Dehesi ranking first, followed by Umm Samrah, and Umm Hirenah and Umm Sreha having low probability of flash floods.
