It has been raining severely in the last couple of months in Thailand. Thai people have to
bring umbrella or raincoat whenever they go outside. Torrential rains caused heavy flooding
in southern Thailand and even capital city of Bangkok. Ron (2009) reported “the flooding
threat to Bangkok comes from three factors, especially during the monsoonal season. Heavy
rains could combine with high tides and runoff from the north into the Chao Phraya River.”
