Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by: Tayfun Kurt Abstract This study introduces a new integrated approach to drought susceptibility mapping in the Medina Region of Saudi Arabia by combining geomorphometric and hydrological indicators derived from high-resolution ALOS PALSAR DEM data. Using QGIS 3.42, key topographic parameters such as slope, aspect, Topographic Wetness Index (TWI), Stream Power Index (SPI), and the Drought Geomorphological Unit-based Index (Drought Index) were extracted and harmonized within a GIS-based Multi-Criteria Decision Analysis (MCDA) framework. The integrated analysis enabled the identification of spatial patterns of drought risk and delineation of high-susceptibility zones. The results offer actionable insights for targeted drought mitigation, sustainable water resource planning, and environmental management in hyper-arid regions where conventional climatic data are limited. This approach demonstrates th...
