This research was conducted to determine the level of vulnerability to flash floods in the Air Betung sub-watershed. Hazard level mapping is a step taken to determine the level of vulnerability by analyzing slope maps, land use maps, soil texture maps and canopy cover maps. The vulnerability index was analyzed using the FFPI method processed in the Arcgis 10.4 program. The results of the vulnerability index are classified into three classes, namely low class, medium class and high class. Pagar Alam Selatan sub-district is a sub-district that has a high index value, while Pajar Bulan sub-district has the lowest index of flash flood vulnerability in the Air Betung sub-watershed.]]>
