East Asia with a total area of 51.36 million hectares, within the tropical belt will be most influenced [1], [2].
During the 2011 monsoon season occurred the great flood in Thailand. Beginning at the end of July
through October, enhanced by the landfall of tropical cyclone Nock-Ten, have led to severe flooding that
caused nation’s most expensive natural disaster in 50 years, which makes the floods one of the top five in
modern history of Thailand [3]. The World Bank has estimated 45.7 billion USD in economic damages and

productions as major agricultural products [3], [5]. Therefore, the purposes of this study explored the impact
assessment of flooding on Thai Rice production in CPRB during 2011 to 2012, and suggest the solution of
