Lessons learned from 2011 Thailand flood and preparation for the next
Start of integrated water circulation information server in Thailand
Institute of Industrial Science
In Thailand, effective prediction techniques for integrated management of hydro-meteorological data and water-related disasters is insufficient, and accurate information transmission of the danger of water-related disasters is not available.
As part of Science and Technology Research Partnership for Sustainable Development (SATREPS), which is structured as a collaboration between the Japan Science and Technology Agency (JST) and the Japan International Cooperation Agency (JICA), the research team of the project titled “Integrated Study Project on Hydro-Meteorological Prediction and Adaptation to Climate Change in Thailand (IMPAC-T)” led by Professor Taikan Oki, Institute of Industrial Science, the University of Tokyo, developed a numerical simulation model that predicts the water level and river discharge of the Chaophraya river and an integrated water circulation information system including real-time data collection and visualization of simulation results. These results have been made open to the public from January 2014. This enables near real-time prediction of floods affected areas when an abnormal event (for example, heavy rainfall in the upstream area of the river basin) occurs, and provision of accurate information transmission in a real-time basis, which was not available at the time of the severe flood in 2011. As a prevention measure for future flood disasters, it will be possible to calculate flood transitions using the real-time and forecasted rainfall distributions, and estimate the amount of damage reduction such as in inundation area and depth from changes in reservoir operations.
The results of this IMPAC-T project have been issued by the international research journal Hydrological Research Letters as a special collection. This is expected to contribute to the future development of science and technology in water-related fields, not only in Japan but also in Thailand.
