Mekong - The river of nine Dragons
The Mekong's flow begins to rise around the end of May and reaches its highest point in September; it ranges from 1900 to 38,000 cubic metres per second depending on the season. A tributary of the river that empties into the Mekong at Phnom Penh drains Cambodia's Tonle Sap Lake. When the Mekong is at flood stage, this tributary reverses its flow and drains into Tonle Sap, thereby somewhat reducing the danger of serious flooding in the Mekong Delta. Unfortunately, deforestation in Cambodia is disturbing this delicate balancing act, resulting in more flooding in Vietnam's portion of the Mekong River basin.
In recent years seasonal flooding has claimed the lives of hundreds and forced tens of thousands of the region's residents to evacuate from their homes. In some areas, inhabitants are not able to return to their homes until the waters fully recede several months later. Floods cause hundreds of millions of dollars in damage and have a catastrophic effect on regional rice and coffee crops.
Living on a flood plain presents some technical challenges. Lacking any high ground to escape flooding, many delta residents build their houses on bamboo stilts to avoid the rising waters. Many roads are submerqed or turn to muck during floods; all-weather roads have to be built on raised embankments, but this is expensive. The traditional solution has been to build canals and travel by boat. There are thousands of canals in the Mekong Delta - keeping them properly dredged and navigable is a constant but essential chore.
A further challenge is keeping the canals clean. The normal practice of dumping all garbage and sewage directly into the waterways behind the houses that line them is taking its toll. Many of the more populated areas in the Mekong Delta are showing signs of unpleasant waste build up. One can only hope the government will take stronger measures to curb this pollution.
