For the more or less 10 million people living in Thailand’s capital city of Bangkok, flooding is a common and recurring phenomenon. This is partly due to the city’s geographic location at the southern end of the Chao Phraya River Basin, as well as its low-lying terrain of around 1.5 metres average elevation above mean sea level. The city normally experiences six months of rainy season every year from May to October. However, conditions are soon expected to worsen for much of Bangkok.
