Performance of a dry detention pond: case study of Kota Damansara, Selangor, Malaysia

Abstract

The Urban Stormwater Management Manual for Malaysia (MSMA) was published in 2001 by the Department of Irrigation and Drainage (DID), which promotes Best Management Practices (BMPs) aimed at stormwater management at the source. The construction of detention ponds has been strongly encouraged for water quantity control for new housing developments. This study focuses on the evaluation, using the InfoWorks Collection Systems (CS) model, of the effectiveness of a constructed dry detention pond built in 1996 located at Kota Damansara, Selangor. Hydrological and hydraulic data were collected for model calibration and verification. The study indicates that the dry detention pond can achieve its design goals, catering the flow from a 100-year Average Recurrence Interval or ARI storm and complies with the design requirement in the MSMA for major urban stormwater systems.
