Overtopping risk of high-hazard embankment dam under climate change condition

river can be obtained from the GIS features in HEC-HMS model after completing the delin- eation process, while study by the authors of [27] still used the ArcGIS tool to determine the physical parameter of the catchment for the input in the HEC-HMS model. All these physical characteristics then will be used to determine the input parameters by using the Malaysia guideline from [23]and calibrated by using guidelines from [14] as tabulated in Table 3. Fig 4. Subareas basin model setup. The dam catchment divided into 6 sub catchments coded by S1 to S6. https://doi.org/10.1371/journal.pone.0311181.g004 PLOS ONE Climate change PLOS ONE | https://doi.org/10.1371/journal.pone.0311181 February 27, 2025 10 / 32
