Pakistan has suffered a devastating flood disaster in 2010. In the Kabul River basin (92 605 km(2)), large-scale riverine and flash floods caused destructive damage with more than 1100 casualties. This study analysed rainfall-runoff and inundation in the Kabul River basin with a newly developed model that simulates the processes of rainfall-runoff and inundation simultaneously based on two-dimensional diffusion wave equations. The simulation results showed a good agreement with an inundation map produced based on MODIS for large-scale riverine flooding. In addition, the simulation identified flash flood-affected areas, which were confirmed to be severely damaged based on a housing damage distribution map. Since the model is designed to be used even immediately after a disaster, it can be a useful tool for analysing large-scale flooding and to provide supplemental information to agencies for relief operations.
