“…WDW exemplifies one of the risky areas in the Sinai Peninsula due to slope and channel erosion, mass-wasting, and flash floods (Abuzied and Mansour 2019). Wadi Dahab was investigated as a strategic location for management and development plans in many studies (Selmi and Abdel-Raouf 2013;Abuzied and Mansour 2019). WDW is mainly steep topography, with hilly areas, and lowland areas which are already developed (Abuzied and Mansour 2019).…”

This study is an attempt to assess slope and channel erosion for modeling their implications on debrisflow occurrences in Wadi Dahab watershed (WDW). Remote sensing and Geographic Information System (GIS) were integrated to appraise erosion rates from a hillslope and channel storage throughout WDW. A mass-wasting database was built initially for modeling hazard zones and validating the final map using a bivariate statistical analysis. An Erosion Hazard Model (EHM) was developed to evaluate the erosion intensity and sediment yield throughout WDW and to prognosis the hazard zones due to debris-flows. The EHM was developed based on hydrological and geomorphic controls which are responsible of disintegrating bedrocks, delivering detritus downslopes, and accelerating debris through channels. Multi-source datasets including topographic and geologic maps, climatic, satellite images, aerial photographs, and field-based datasets, were used to derive factors associated with the hydro-geomorphic processes. A spatial prediction of erosion intensity was obtained by the integration of both static and dynamic factors generated hazards in GIS platform. The erosion intensity map classifies WDW relatively to five intensity zones in which the most hazardous zones are distributed in steepsloping terrains and structurally controlled channels covered by metamorphic and clastic rocks. The erosion intensity map was correlated and tested against the debris-flows dataset which was not used during the spatial modeling process. The statistical correlation analysis has confirmed that the debris-flow locations increase exponentially in the highly erosion intensity zones. The holistic integration approach provides the promising model for forecasting critical zones prone erosion intensity and their associated hazards in WDW.

This study delineated flash flood hazard zones leading to vast destruction to infrastructure, property, and loss of life. An integrated approach using remote sensing and geographic information systems was applied to reveal flash flood-prone zones. The study approach evaluated topographic, geologic, and hydrologic factors holistically to assess these hazard zones. The morphometric characteristics of Wadi Dahab sub-basins were supported by topographic, geologic, and hydrologic information. Data from Shuttle Radar Terrain Mission and Operational Land Imager imagery were analyzed to characterize hydrological morphometrics, lithology, soil types, and land use. A Natural Resources Conservation Service model was selected to calculate runoff depth at ungauged watersheds. A spatially distributed unit hydrograph was adopted to create the flow time and runoff velocity. The Flashflood Hazard Model was developed by spatial integration of all contributing factors. An analytical hierarchy process was adopted for the logic ranking of the effective factors. The flash flood hazard map classifies Wadi Dahab basin into five relative hazard zones: very high, high, moderate, low, and very low. The highly hazardous zones are distributed at the downstream of Wadi Dahab basin corresponding to steep topography and Precambrian rocks. The hazard map was validated using the flash flood markers defined from field observations.
