Abstract

Flood disasters are one of the most common natural disasters in Indonesia, including in the Special Region of Yogyakarta. Flooding can occur when water bodies are unable to accommodate water discharge that exceeds their capacity. A flood that occurred several years ago was caused by Cyclone Savannah, affecting Bantul Regency, particularly the Pundong District. The impact of this flood disaster resulted in significant losses in the social and economic sectors. Studies of flood-prone areas are essential to assist the community in flood disaster mitigation. This study aims to analyze the flood vulnerability level in Pundong District, Bantul Regency and to identify the most dominant factors contributing to flooding in the area. The study utilizes secondary data, including the Digital Elevation Model (DEM), Sentinel-2A imagery from 2023 covering parts of the Special Region of Yogyakarta, land use data, rainfall data, and soil type data. The research employs a scoring and overlay method on each parameter, using four factors: rainfall, land use, slope, and soil infiltration, which are classified into three flood vulnerability classes. The results show that the low vulnerability class covers an area of 328.23 ha (14.21%) in parts of Seloharjo Village. The moderate vulnerability class covers 231.39 ha (10.02%) in parts of Seloharjo Village. The high vulnerability class covers 1,749.76 ha (75.77%) and includes Srihardono Village, Panjangrejo Village, and parts of Seloharjo Village, with rainfall intensity and slope being the most dominant factors contributing to the flood disaster.
