Implementation of Remote Sensing and GIS Techniques to Study the Flash Flood Risk at NEOM Mega-City, Saudi Arabia | Chapter 6 | Techniques and Innovation in Engineering Research Vol. 5

 Southern Red Sea inundation is common. Assessing flood-likely development risks helps decrease history and property threats. It tries to increase flood awareness and advocate landlord steps to lessen risk. DEMs and terrain data were resolved by RS and GIS. Fifth-through seventh-order Rivers were studied. Morphometric study assessed the area’s sudden rainfall danger. NEOM has 14 catchments. We persistent each catchment’s area, circumference, maximum length, total stream time, minimum and maximum elevations. It also uses detached sensing. It categorizes Landsat 8 photos for land use and cover maps. Image categorization involves excellent Landsat satellite countenances and secondary dossier, plus user occurrence and knowledge. This study secondhand the wetness index, elevation, slope, stream capacity index, topographic roughness index, normalized dissimilarity vegetation index, powder transport index, stream order, flow accumulation, and terrestrial formation. Analytic order considered all earlier tests (AHP). The geometric regularity index GCI (0.15) and the consistency percentage CR (4.3%) are calculated. The study revealed five degrees of inundation risk for Wadi Zawhi and four for Wadi Surr, from very high to very low. 9.16% of Wadi Surr is ready to very high inundation, 50% to high inundation, 40% to low inundation, and 0.3% to very low inundation. Wadi Zawhi’s flood risk is 0.23% high, moderate, reduced, or extremely low. They’re in Wadi Surr and Wadi Zawhi. Flood plan helps prepare for crises. Flood-prone regions should supply instructions resilience.
