| Summary: | Flash flood occurring from fast development and socioeconomic
growth within Klang Valley has imposed a huge strain impact onto the entire
urbanized areas. Accurate techniques in ascertaining flood estimation and
prediction would normally be able to propose beneficial solutions in
counteracting the phenomena. However, this would require up to date
reliable data and effective hydrological modeling coupled to socio-economic
studies. These types of studies is time consuming and costly. Complex
models produce large quantities of result and difficult for people without
specialized backgrounds to understand . New modeling techniques and
computer visualization would improve the timeliness and accuracy of
hydrological analysis and flood forecasting. With the limited data, complex
hydrological approaches could be accomplished.This study intends to illustrate the capability of MIKE 11 GIS to
simulate the flood map for Sungai Kayu Ara in modeling the flood mapping.
Direct runoff hydrograph could be generated from the rating curve to be used as the input data in preparing the simulation for the flash flood . Crucial
ground survey data as one of the significant criteria in producing reliable
flood elevation profile is examined .
The study also shows that Geographical Information System (GIS) is
capable to integrate spatial data and applying spatial simulation from limited
data. It is able assist in the understanding of the flooding physical processes
and in facilitating the decision-making . The flood simulation can further be
modeled with changes in land-use and curve numbers features pertaining to
the future development growth.
In achieving the above objective, flood modeling was carried out on
Sungai Kayu Ara catchment area. In the process MIKE 11 GIS was used as
a database and data processor. The available hydrological (rainfall and
water-level) data acquired from the data of 1996 to 1998 , were used to
produce the flow simulation during the time of the storm event. This result of
the study shows that it is possible to use limited hydrological data to map the
flash flood using MIKE 11 and MIKE 11 GIS. However, ground survey data
with cross sectional intervals of 75 m to 100 m used in the study was found to
be insufficient to provide adequately the elevation profile and further
refinement is neccessary. |
