dc.description.abstractMuda River has been for many years experiencing seasonal floods and causing serious damage and economical loss to human settlements and property in the Muda basin. The 2003 flood was the most devastating event throughout the history of the river. The geomorphological changes, flood behavior and impacts of the Muda River have been investigated in this study using integration of specialized software packages and computer modeling techniques to envisage the consequent changes projected on the river, and assisting in predicting and communicating the flooding risk. Ground surface roughness was delineated through several field visits to the study area. This ground roughness acts as a significant input data for hydraulic modeling purpose. The results of one-dimensional hydrodynamic modeling showed a wide spatial extension of flooding inundation in the vicinity of the floodplain, and indicated damage severity on households and agricultural land use features located in these highly inundated areas. Hazard assessment and risk analysis on these two land use types revealed that the economical damage of the 2003 flood (RM 27.6 million) was five times than that of the last flood (1982) in a 20-year-period (RM 3.87 million). This enormous loss can be attributed to the dramatic changes imposed on the riverine system by much historical and contemporary unsustainable human exploitation of the Muda basin land assets, increasing its vulnerability to erosion hazards and decreased ground surface roughness.en_US
