Abstract

The Probable Maximum Flood (PMF) is defined as the flood that may be expected from the most severe combination of critical meteorological and hydrologic conditions. PMF also has physical meanings which provide an upper limit of the interval within the engineer must operate and design. The PMF is generated using the input values of Probable Maximum Precipitation (PMP) in this study area. Hydrologic Engineering Center-Hydrological Modelling System (HEC-HMS) software has been chosen to simulate the rainfall-runoff routing process through a dam spillway, the inflow discharge, and also the maximum storage of Cameron Highlands Dam due to extreme rainfall event. This software is a single based event and is suitable for Cameron Highlands catchment case study.The study area is Sultan Abu Bakar dam which is located in the upper catchment of Cameron. The results for PMF found out to correspond to PMP values, and yielded a peak discharge of 4259.7m3/s, 1661.0m3/s and 1264.4m3/s for 1 day PMP, 3 days PMP and 5 days PMP respectively. The values from PMF hydrograph will be used in MIKE 11 as an inflow hydrograph in the model to predict the dam breach outflow hydrograph at Sultan Abu Bakar Dam. Discharge generated from frequency storm method will be invaluable for future flood hazard and risk assessment studies.
