The objectives of the study are: 

• To identify areas of flood inundation in Sungai Pari Catchment Area

• To provide better understandings on depth-of-flood details, spatial variation in flood risk mapping and sediment transport based on hydrological, hydraulic and socio-economic factors for Sungai Pari Catchment Area

• To produce digital flood risk maps for Sungai Pari Catchment Area that can be updated easily

Severe flooding has occurred in recent years at several parts of Malaysia, both as localized flash floods and as basin-wide floods on major river systems. Some of the badly affected areas are situated at the river basins in Penang (Juru River Basin), Pahang (Pahang River Basin), Terengganu (Setiu River Basin) and Perak (Kinta River Basin). By their nature, floods are generated by the random coincidence of several meteorological factors but man's use of the river catchment also has an impact upon the severity and consequences of the events.

There is no particular attempt yet in Malaysia to provide digital flood risk maps taking into account of sediment movement along the river channel.  Ab. Ghani et al. (1998) attempts to quantify the effects of sediment movement and corresponding cross-sectional changes in producing the flood levels. Successful applications of several sediment transport models such as HEC-6 and FLUVIAL-12 (Ab. Ghani et al., 1998) indicate the possibility of extending the obtained results in mapping the flood prone areas by incorporating sediment transport bearing in mind the physical aspects of river ability to change its boundary (Ab Ghani et al., 2000). 

A sediment transport equation applicable for rivers in Malaysia (Sinnakaudan et al., 2006) was developed based on sediment data collection carried out from 1994 until 2002 (Chang et al., 2005).  It was later embedded in a modified version of HEC-6 model and named SEDFlood model (Sinnakaudan et al., 2002; 2003).  A user-friendly, menu-driven GUI for 2D and 3D digital floodplain delineation was developed based on ArcView GIS and SEDFlood tight coupling procedure.  Flood risk maps for the present and future land use can be produced using the SEDFlood model GUI (Sinnakaudan et al., 2004).
