| Summary: | Malaysia experienced two types of monsoon
which is North-East monsoon and South-West
Monsoon. During this monsoon season, Malaysia received
abundant of rainfall and this has resulted in
flood in certain areas especially east coast and southern
par! of Peninsula Malaysia. This disaster has resulted
in'big losses either in term of facilities, infrastructures,
money or life. Thus, flood mitigation project must be
carried out to reduce the losses. One of the most effective
ways in managing and identifying the flood magnitude
is by using modeling. Thus, this study was con.
ducted with the aim to identify the flood area by using
rainfall-runoff model. InfoWorks RS was utilized as
the software engine to model the flood. The required
data such as rain-fall, water level, flow rate and maps
were retrieved from respective authorities and field
works. The duration of 2 years to 200 years of return
period were used to calculate and generated rainfall
pattem. The result clearly shows that the study area is
susceptible to flood if the ARI more than 25 years was
being used. The maximum of water level is 11.94 m
with the flow rate of 1325.68m3/s. Calibration process
was conducted to verify the result by comparing the
real data from flood event in 2007. The difference between
the measured and calculated result is 0.02%.
This can be concluded that the produce result can be
acceptable.
