The actions taken have been categorized into 3 i.e. Before, During and After the flood. Different interventions were carried before the occurrence of the flood, during and even after the floods. Department of Drainage and Sewerage (DDS) had the main responsibility in flood regulation of the BMA. Underlined with the perception to protect and drain floodwater out of the city as fast as possible, the agency emphasized the structural means of dykes, levees and floodwalls as the main prevention measures. After extensive flood damage in 1995 under the king’s advice, several authorities convened for flood mitigation measures including the assistance from the Chaipattana Foundation, a NGO established in 1988 to develop projects of national and social benefit.
To prevent floodwater to spread to East of Bangkok, the DDS build flood defense dikes beside the Rangsit Canal located in Lak Hok Sub District (beside the Hok Wa Canal and along the royal initiative water ridge). In addition, sandbags were erected along the Phaholyothin Road starting from the Rangsit Bridge to the Prapa Canal. The temporary dike (8.2 km long and 3 m above MSL) later failed in its operation to protect Bang Khen Bueng Kum, Lad Phroa and Khlong Sam Wa districts from being flooded.
The Strategic Committee for Water Resource Management SCWRM collaborated with the Japan International Cooperation Agency (JICA) assigned to conduct the comprehensive flood management plan for the Chao Phraya River Basin under the supervisory panels consisted of the representatives from the Royal Irrigation Department (RID) and the Department of Water Resources (DWR).
