Short summary

In 2011 the Chao Phraya River basin received about 1400mm rainfall, which was 1.2 times more than past large floods in 1995 and 2006. The long-term rainfall-runoff-inundation simulation and its water balance analysis revealed high elasticity in the flood inundation volume (4.2%). 1.2 times more rainfall might result in 1.6 times more flood inundation volume in 2011. The high sensitivity of inundation should be well recognized for a better understanding of the flood hazard characteristics.
