Short summary
We constructed an intensity–duration thresholding technique required to develop an early-warning system for the Faifa Mountains in Saudi Arabia. The study uses radar imagery, satellite-derived rainfall data, archival imagery, and limited field data. The study presents a significant development in the application of radar for hydrogeological and geomorphological studies as it provides better resilience towards nonoptical conditions.
