A combination of topographic analysis using digital elevation models (DEMs) and hydrological modeling can help identify natural drainage swales in the desert that are prone to flash flooding. DEMs can reveal the terrain's slope and elevation variations, while hydrological modeling can simulate water flow and identify areas where water is likely to accumulate during flash flooding events. Field verification may also be necessary to confirm the presence of natural drainage swales.
I assume you might be asking about the flood plain. The drainage basin is the very large area that feeds a river or stream. The flood plain is an area that is subject to flooding on a fairly normal basis. Building on the flood plain interrupts the natural pattern of flooding. The river will flood somewhere, the water has to go somewhere. if not on the natural flood plain perhaps in a city or town downstream.
