Flood is an event where the normally dry land becomes inundated by water or the water level that exceeds normal in the river and overflows caused by high rainfall and low topographical conditions and basins. The purpose of this study is to identify the distribution of potential areas prone to flooding. and analyze the level of flood vulnerability in Satui District.

This research was conducted using the Overlay (intersect) method with a scoring fan. The weighting of the parameters used are the data of the slope, land height, rainfall, and land use. Where each parameter is weighted and scored according to its respective classification where the results are multiplied and then the scores of each parameter are added up which are then overlaid using ArcGIS 10.6 Software. the use of this software utilizes a Geographic Information System (GIS) that can explain and present objects and data on Flood Vulnerability areas in digital form.

The results obtained in the form of a flood susceptibility map consisting of four classes/classifications, namely: not vulnerable, less vulnerable, vulnerable, very vulnerable where very vulnerable locations are scattered in the area of ??Satui District with a very vulnerable class with an area of ??18340.89 Ha or about 20 ,87%, vulnerable class with an area of ??46746.71 Ha or about 53.18%, less vulnerable class 22507.22 Ha or about 25.61%, non-vulnerable class with an area of ??304.58 Ha with a percentage of 0.35 %, of the area of ??Satui sub-district, Tanah Spice Regency.
