The occurrence of severe floods in recent years globally as well as in many parts of Malaysia is an indication of both climate change and human interference in land use change. This requires for an integrated flood risk management approach and a shift from conventional structural flood mitigation. Flood modelling is an important part of flood risk management. In this study, development of one dimensional (1D) hydrodynamic model for Pahang River was performed in HEC-RAS 5.0 using combinations of surveyed data with spatial-extracted cross sections and recorded stream flow. The study area had been hit by several extreme floods that caused substantial property damages and loss of lives. This study focusses on the recent 2007 and 2014 flood events. Analyses of water levels, stream discharges and river cross sections were carried out based on the data gathered. A set of flood levels were obtained as the outputs of the hydraulic model and the accuracy of the simulated flood levels were validated. It was found that the model predicts a good output agreement with \(R^{2}\) = 0.96 and \(R^{2}\) = 0.82 for the 2007 and 2014 flood events respectively. |
