| Summary: | The Cameron Highland-Batang Padang Hydro-Electric Scheme (HES) is located between two states which are Pahang and Perak. The Cameron Highland Hydro-Electric Scheme consists of four cascading dams with individual power stations constructed known as Sultan Abu Bakar Dam, Jor Dam, Mahang Dam and Ulu Jelai Dam. Dam break could bring disaster leading to huge property damage and fatalities. The main goal of this project is to develop dam-break modelling utilizing MIKE 11 and MIKE FLOOD 2D for Cameron Highland HES. To show the extent of inundation downstream caused by the flood volumes generated by the dam break scenario, flood hazard maps have also been produced as part of this study�s hydrodynamic modeling results for dam break scenarios of Probable Maximum Flood Failure (PMF) for the respective dams in Cameron Highland HES. It is found that the maximum outflow produced from a PMF dam failure at The Sultan Abu Bakar dam is 1108 m3/s, the�Jor dam is 1901 m3/s, the�Mahang dam is 464 m3/s, and the�Ulu Jelai dam is 55,906 m3/s. The associating inundation extents at the downstream areas resulting from the PMF dam failure�s flood volumes at The Sultan Abu Bakar dam is 1.58 km2, Jor dam is 83.69 km2, Mahang dam is 51.50 km2, and Ulu Jelai dam is 815,379 km2. The simulated dam breach flood depth and expected flood wave arrival times at critical locations obtained from this study are beneficial to the dam operator in preparation for the appropriate emergency action plans during occurrences of extreme events. � The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023. |
