The great flood occurred from August to December 2011 spreaded through the area in Thailand along Chao Phraya
River which flows from north to south. About 18,000 square kilometers, the same size to Kanto plain were attacked
by flood. Not only the farmland was damaged, the industrial zones and the city zones including Bangkok were also
affected. Some areas were a long-time flooded over 1 month.

During flood, inundation was found not only along the river shore but also from drainage system and this caused
a fear of health risk widespread of waterborne disease caused by contaminated water. Actually, in case of the long-time
flooded as this time, it is an unavoidable case to resume daily life and revive urban activities before waiting for
the end of the flood. Besides, from the fact that the more frequently in contact with floodwaters, to figure out the
water quality is a very important key to take the countermeasure against the health risk during flood period.

This survey was urgently conducted by visiting the areas that are still flood-affected in November and December 2011.
The investigation of flood situation and measurement of floodwater quality in the different places and different times in
order to observe a distribution and change in water quality along the time are the objective of this survey. In addition,
this web site provides the images taken at the survey sites, aerial images taken from a helicopter, and the results of
water quality analysis.
