Modelling large-scale flood inundation considering dam operation during the 2011 Thai flood

What is it about?

Suboptimal operation of dams are usually blamed when immense flooding occurs downstream. However, such claims are difficult to confirm due to our limited understanding of complex natural-human processes which contribute to a flood event, especially on a large scale. One of the questions answered by this research is: did suboptimal operation of reservoirs contribute to the immense Thai flood in 2011? We have shown through modelling techniques validated by satellite observation that the operation of the two huge reservoirs in Chao Phraya, Thailand actually reduced the flood extent and flood depth throughout the basin. However, our study also suggests that simple modifications to the reservoir operation can result to further flood reduction.
