Lantaran daripada pembangunan yang pesat, banjir kian menjadi. Senario ini semakin meruncing akibat sistem saliran yang tidak sesuai di kawasan perumahan. Sekiranya keadaan ini dibiarkan berlanjutan, besar kemungkinan ia akan membawa risiko banjir yang lebih serius dan lebih kerosakan harta serta kehilangan nyawa. Sejak pelaksanaan Manual Saliran Mesra Alam (MSMA) pada 2001 oleh Jabatan Pengairan dan Saliran, langkah-langkah pengurusan yang baik melalui pembinaan kolam takungan adalah digalakkan. Selepas 8 tahun pelaksanaannya, kajian untuk mempertimbangkan semula keperluan pembinaan kolam takungan dengan menilai keberkesanan kolam takungan dari segi kuantiti melalui kaedah numerikal adalah amat diperlukan. Due to the rapid development, flooding occurred progressively. This scenario is worsened if improper drainage systems were implemented. The inattentiveness to all the problems occurred will generate the possibility for more severe flooding risk and creates further damages of property and loss of lives. Since the implementation of Urban Stormwater Management Manual of Malaysia (MSMA) in 2001 by Department of Irrigation and Drainage, Malaysia, the Best Management Practices (BMPs) through construction of detention ponds have been encouraged. After 8 years of implementation, there is a need to reconsider the recommendation of constructing detention pond for water quantity control by evaluating performance of the constructed dry detention ponds using computer modelling.
