The previous standard method of drawing flood maps often requires a significant amount of time depending on accuracy and personnel availability however, the technique proposed here is capable of generating a flood map within one minute. The proposed methodology was performed by linking a dynamic numerical analysis model (DAMBRK) with a random forest regression technique. Therefore, this study aims to propose methodology that is capable of generating flood maps rapidly for any dam inflow conditions. In order to prepare an efficient flood response, techniques should be considered that are capable of generating flood maps promptly while taking dam inflow conditions into account. However, rainfall and flood patterns exhibited in the context of climate change can be extremely diverse. Generally, calculation of dam-break discharge in accordance with dam inflow conditions, calculation of maximum water surface elevation as per hydraulic channel routing, and flood map generation using topographical data are prepared for the purposes of creating an EAP. ![]() An EAP is a disaster action plan that can designate evacuation paths for vulnerable districts. ![]() An emergency action plan (EAP) for reservoirs and urban areas downstream of dams can alleviate damage caused by extreme flooding.
