The concern over floods in the northern coast of Java is more pronounced. The increasing frequency of flood events, material damage and death rates underscore the importance of integrated efforts in controlling floods there. Brebes Regency has good prospects for economic growth and infrastructure. However, because its location on the north coast of Java makes it vulnerable to flooding. Considering this, it is necessary to carry out a comprehensive evaluation of flood hazards and risk assessment in Brebes Regency, as part of efforts to mitigate flood disasters and encourage the development of Brebes Regency as a resilient city. Flood hazard and risk assessment involves the use of spatial analysis techniques, which include the process of examining the level of vulnerability, determining flood hazard zones, and creating a flood risk map. Vulnerability analysis incorporates land use, population density, and economic activities. Flood hazard zoning assessment were carried out using rainfall data, tidal water levels and topography. The findings of the risk assessment indicate that the northern region of Brebes Regency has a high level of risk of flooding. Moreover, these flood risk maps can serve as a valuable tool to inform and guide the development of flood mitigation strategies and infrastructure.
