>For post-development = 1688.549 1/s

> PSD (Below Ground) = 1461 1/s

OSD DESIGN

Location: KL
Area: 40 ha

PreDevelopment: assumed 100% pervious (Category 7-park & meadow)
PostDevelopment: 80% impervious (Category 1 - roof)
20% pervious (Category 7 - park & meadow)

RESULTS:
PSD (2yrs ARI MINOR System):1374.6 l/s
SSR (10 trs ARI):
40% above ground = 340.1 m3
60% below ground = 585.9 m3
