HAZARD AND VULNERABILITY PROFILE
Due to rapid urbanization of Bangkok, waterbody such as ponds, wells, canals, and ditches were filled up and replaced by buildings and other structures. This often caused flooding and became a severe problem accordingly. The major 9 flooding in Bangkok in the past were in the years 1942, 1975, 1978, 1980, 1983, 1995, and 1996. Flooding in the year 1983 was considered the most severe and caused great damage which cost around 6,600 million baht The causes of flood are as follows: - Heavy rainfall in short period of time results in inability to immediately drain water from roads, lanes and houses causing temporary flooding. - Run-off from the northern and eastern parts flowing through Bangkok due to the slope of ground level. This mostly causes flooding problem in the eastern part of Bangkok - Excessive run-off from the North and Chao Phraya River Basin flowing through Bangkok to the sea causing overflow and flooding in the area. - The effect of high tide from the sea which occurred in the same time of excessive run-off from the North through Bangkok causing high water level in Chao Phraya river. - Land subsidence due to pumping of large amount of underground water which makes the area subside to the level lower than mean sea level causing difficulty in draining of inundation. - Insufficient drainage system
