Abstract

Floods are natural disasters that often occur in Indonesia. Floods occur due to excessive water flow that inundates an area for a certain period of time. Floods can occur suddenly or gradually at any time, resulting in significant losses. According to the National Disaster Management Agency, from 2022 to 2024, Indonesia experienced 4,026 flood disasters, 699of which occurred in West Java Province. On January 25, 2025, one of the areas in West Java, specifically Pasteur, Bandung, experienced a flood disaster triggered by the suboptimal performance of its drainage system and high rainfall intensity. Therefore, this research conducted flood modeling using the shallow water equation with the finite difference method. The purpose of this research is to minimize losses caused by flood disasters. Based on the research results, the Pasteur area has the potential to experience flooding if it experiences high rainfall intensity, which is also exacerbated by the inadequate drainage system. The modeling results indicate that the depth of the floodwater increased significantly, reaching a maximum depth of approximately 1.3 meters, after which it gradually decreased until it receded in about six hours.
