![]() Fluvial flooding results from an increase in a stream or river’s water level that overflows into the surrounding area and coastal areas, while pluvial flooding results from excessive runoff from rainfall that causes a rapid rise in water levels 10. ![]() Numerous scientists have recognized that hazard zoning has a role in spatial planning processes 8, 9. To lessen flood damage, researchers have examined floods, created flood hazard and flood hazard risk maps, and analyzed floods 6, 7. The best method for reducing flood disaster risks and promoting decision-making is geospatial technology 3, 4, 5. Geospatial planning is necessary to lower the danger of floods, a natural hazard 1, 2. The geographic breadth of flood susceptibility and risk is thoroughly examined in this paper, as is the significance of spatial planning in the Awash basin. The spatial autocorrelation tool’s Z score and p-value for the standard residuals are, respectively, 0.7 and 0.4, indicating that they were neither clustered nor scattered. Model number 31 was found to be the best fit model, having the highest Adjusted R 2 value of 0.8 and the lowest Akaike’s Information criterion value of 1536.8. For the GIS domain, a total of 31 models were built using exploratory regression. Exploratory regression analysis showed that the existing land use is the main factor influencing flood susceptibility. Each constituent was assigned a weight based on its susceptibility to the danger, which was classified into four classifications. The likelihood of flooding was assessed using eight independent variables: elevation, slope, rainfall, drainage density, land use, soil type, wetness index, and lineament density. The Awash basin was picked because it is continuously in danger both spatially and temporally. Understanding the temporal and spatial patterns of flood in the Awash River basin, which is located in Ethiopia’s Afar region, is crucial.
