Sensitivity analysis of a flood inundation model to spatially-distributed friction coefficients obtained using land cover classification of Landsat TM imagery

In this paper, land cover was predicted from Landsat TM imagery and used to generate spatially-distributed friction coefficients. Flood inundation was then predicted using the raster-based model LISFLOOD-FP, based on friction and three different elevation models. Sensitivity of LISFLOOD-FP to spatially-distributed friction was assessed. It was found that effect of friction on the ?ood wave is small when compared to the underlying elevation, but is greatest during the recession phase of the hydrograph.
