Flood inundation caused by cyclone Nargis is simulated on the Irrawaddy delta with a newly developed two-dimensional rainfall-runoff-inundation model. The primary objective of the model is to provide useful information for emergency responses during or at immediately after flood disasters. This study applies the model to simulate the storm surge flooding with the boundary condition of surge water level at the coastal line. The simulated result was compared with an inundation map produced by remote sensing. The reasonable agreement between the simulated and the remotely sensed inundation map confirmed the model reproducibility for storm surge inundations at the large areas. The simulation shows also the importance for considering rainfall-runoff processes for adequate inundation simulations.
