| description | Extreme flood cause disasters such as loss of life, property and resources. In Malaysia,
the occurrence of floods is due to a lot of factors. One of the major factors is because of
the rapid development especially in floodplain area in Lembah Klang and Kuala
Lumpur. The increase in the development will automatically increase the impervious
area and as the result, the runoff will also increase. This increase will produce more
water from the rainfall in the river and this is why flooding happens so often in these
areas. If flood can be predicted, control and managed systematically, the losses due to
flood can always be prevented or at least minimized.
This study focused on the utilization of a computer program called HEC-HMS
to estimate the flood discharges for various return periods. The Sungai Galas catchment
at Dabong, Kelantan was used as a case study. The total catchment area of Sungai Galas
is 3970 km2. Recorded hydrologic data from Sungai Galas basin was used in evaluation
and testing of the model. Model evaluation involved calibration and verification.
The rainfall and discharge data were obtained from Hydrology and Water
Resources Division, the Department of Irrigation and Drainage. Records are available
since 1980. Simulation was performed using data from a selected event for calibrating
the model parameters. |
