Flood hazard and flood risk can be reduced based on two general approaches namely structural and non-structural flood mitigation approaches. Structural approach of flood mitigation focuses on engineering approach in reducing flood impact for example building dam, flood wall, flood dike and so on. On the other hand, non-structural approach believes that flood impact can be reduced for example through enhancing community capacity to cope with flood, efficient evacuation and emergency response, flood warning system and etc. Both approaches should be directed towards comprehensive flood hazard mitigation planning covering operation of an overall program of corrective and preventive measures for reducing flood damage. The aim of this research/project is to investigate and support the structural and non-structural approaches in reducing flood damage by combining geospatial technology and hydrodynamic simulation. This is supported by the following specific objectives: 1) To evaluate the performance of proposed dam constructions at Sungai Kemubu and Sungai Lebir in reducing flood hazard based on flood simulation, 2) To generate flood hazard map for different magnitude of floods that can be used to support emergency response and 3) To determine suitable area for evacuation regardless of different magnitude of expected flood. The first objective focuses on evaluating the effectiveness of current proposal for dam development (structural approach) in reducing flood impact. This will involve intensive modelling of dam structure and its operational aspect in hydrodynamics modelling. The modelling will account different magnitudes of flood events. The second objective leans towards reducing flood impact based on non-structural approach. The flood characteristics maps generated by previous objective will be used to generate relevance flood hazard map by accounting different capability of people in facing with floods. The multi-temporal flood hazard map can be used to support effective emergency response before and during floods. The final objective will be devoted to determine suitable area for evacuation by considering different information given by the previous objectives. The outcome of this research/project will be a strong framework and tools to evaluate different approach, both structural and non-structural approaches in reducing flood hazard and risk especially in Malaysia. The findings on this research/project can be used by various agencies related to flood emergency response for example Majlis Keselamatan Negara (MKN), Jabatan Pertahanan Awam Malaysia (JPAM), Jabatan Pengairan dan Saliran (JPS) and etc.
