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
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).
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).
