| Summary: | Nowadays, detention ponds are widely used in controlling flood due to its capacity
in storing the additional surface runoff generated from development. The procedures
for the estimation and routing of design hydrographs are presented in the Urban
Stormwater Management Manual for Malaysia (MSMA). However, the complexity
of the calculations and the number of hydrographs that need to be estimated and
routed through the basin makes manual calculation methods very wearisome and
time consuming. Thus, this study was carried out to develop a computerised
modelling using Visual Basic 6.0 to ease and speed up the design process. In order
to develop a computerised modelling of a detention pond, the catchment’s area of
the Sungai Air Salak was analysed. The study focused on the use of a regional
detention pond which can provide satisfactory storage on catchments of more than
80 hectares. In regional detention pond design, Time-Area Method was used to
obtain the inflow hydrograph for pre-development and post-development whereas
Storage Indication Method was applied to design the pond size as well as the outlet
structures. From the study and design that were carried out, a simple and user
friendly computer modelling was developed. This system is easy to use and is able
to provide an effective detention pond design without having to go through MSMA
and design it manually. |
