Soil characteristics that are unique and have the potential for flooding can provide information about a condition of flood vulnerability related to various factors. These factors are interrelated to one another. This study aims to detect Flood Vulnerability through the Topographic Wetness Index (TWI) Method Using a Geographic Information System (GIS) in Pantai Labu Baru Village. This study focuses on knowing the spatial distribution of flood-prone areas based on the TWI value and the accuracy of using the TWI value in determining flood vulnerability in Pantai Labu Baru Village, Deli Serdang Regency, which is one of the areas in North Sumatra Province with a fairly high level of flood vulnerability. Pantai Labu Baru Village is 5 kilometers from the beach. The area of Pantai Labu Baru Village is 1512239.15197 m2, according to the administrative map of the community. Paddy fields, plantations, and fields make up the majority of the land use in Pantai Labu Baru Village. The slope angle ranges from 0° to 19.9°. The TWI value falls between -8.3898 to 10.8494. The degree of slope also suggests a greater TWI value along with the lower slope angle. The degree of vulnerability to floods increases with the TWI value. |
