Pemetaan Tingkat Kerawanan Banjir Rob di Areal Terdampak Banjir Rob Menggunakan Unmanned Aerial Vehicle (UAV) di Kecamatan Medan Belawan Kota Medan

Abstract

Tides frequently cause flooding in the seaside Medan Belawan Subdistrict. When sea levels rise, seawater reaches the land and is hindered by soil or physical structures, resulting in tidal flooding in coastal areas. This study uses unmanned aerial vehicles (UAVs) to map out the size of flood-prone areas in the Medan Belawan region as well as the distribution of tidal flood susceptibility levels. Land height, distance from the shore, distance from rivers, slope, land cover, and soil type are all factors used to calculate vulnerability levels. With the aid of ArcGIS software, this study was carried out over the course of 5 months using scoring and overlay techniques. The research results indicate that out of the total research area of 97.76 ha, 1,444 ha or 1.44% is considered non-vulnerable, 55,111 ha or 56.39% is classified as moderately vulnerable, and 41,205 ha or 42.16% is classified as vulnerable areas. The spatial distribution of tidal flood potential in the Medan Belawan District includes water bodies and settlements. Observations and interviews with vulnerable areas were conducted to validate the research findings.
