Discovery Channel Kuala Lumpur Flood Control: Kuala Lumpur, Malaysiaís Capital, is under siege from flash floods, powerful forces of nature that bring the city to its knees. The source: severe thunderstorms that pound the city for months on end. But Kuala Lumpur is fighting back. A daring construction project will try to bring the mighty floods under control. Massive floodgates across three rivers; six kilometres of canals; giant storage ponds and a state of the art storm water tunnel that doubles as an underground highway. Itís a combination that has never been attempted before. If they can pull it off, Kuala Lumpurís flood control system will truly be a man made marvel.
