Abstract
The problem of flood disasters in the city of Medan is very clear, so information is needed about areas that are vulnerable to flooding. The aim of this research is to determine the risk area for flood disasters using the Geographic Information System in the Medan City area. This research uses spatial analysis of overlay, scoring and weighting of several parameters including rainfall, land elevation, slope slope, soil type, land cover and river network density. The results of this research show that most areas of Medan City are in the very vulnerable and flood-prone category, with a total flood risk area reaching 29,967.14 Ha. areas that are safe from the risk of flooding covering an area of 2458.42 ha, areas that are not prone to the risk of flooding covering an area of 439.78 ha, areas with a risk level that is prone to flooding covering an area of 12213.13 ha and areas with a risk level that is very prone to flooding covering an area of 15455.81 ha . With the total area area, this map reveals that most of the areas in Medan City are in the very flood-prone category (58.24%), followed by areas at risk of being flood-prone (46.06%). Only around 10.92% of the total area is classified as safe or not prone to flood risk.
