3) Loss of floodstorage as a result of
development
4) Urbanisation increasesurface runoff

Constructed to retainflood water in orderto protect areasdownstream of the
dams. Dams constructed for
hydroelectricpurposes also have a
portion of theircapacity allocated forflood detention.
1) Flood Control Dams

2) Canalisation And Related Works
Widening anddeepening ofchannels
Replacement ofundersizedstructures such as
bridges.

3) Flood Diversion Channel Or Tunnel
The SMART system,
Alleviate flooding in thecity centre by divertinglarge volumes of floodwater from entering thecity centre.
The tunnel is designed to
incorporate a stormwaterchannel and a motorwayfor dual purposes.
Expected to ease traffic
congestion.
