| description | The urbanization process leads to a higher possibility of flooding. As the land use
has changed from pervious to impervious surface, the natural infiltration of stormwater
into the ground becomes lesser. The change of land use causes more surface runoff when
there is heavy rainfall. When the drainage capacity is incapable of catering to the volume
of runoff, the flood will occur eventually. In this study, the retention pond is used as a
device to mitigate flooding from happening in the study area. The drainage system in the
study area located in Diamond City in Mukim, Semenyih, Daerah Hulu Langat, Selangor
Darul Ehsan is modeled and simulated using EPA Storm Water Management Model
(SWMM). The objectives of the study are to conduct SWMM modelling on the drainage
system in Diamond City, evaluate the efficiency of the drainage system for different
years ARI, and evaluate the efficiency of retention ponds in the study area for different
years ARI. SWMM is widely used in planning, analysis, and designing urban drainage
systems. The main reason for the chosen study area is largely due that it is very
susceptible to flooding. Based on the calculation, the time of concentration is
21.93minutes where the overland flow time is 5.92 minutes and the drain flow time is
16.01 minutes. Hence, a 30-minutes storm duration is used. Based on the result, the peak
flow at the outfall of the drainage system is 4.46 m3/s for 100 years ARI while the peak
flow for 10 years ARI is 3.85 m3/s. The higher the ARI, the drainage system is more
susceptible to overflow or flooding. The result also shows the percentage of flow
attenuation of the retention pond is around 90%. |
