This study describes the development and
application of a 2D raster-based diffusion wave model
(FloodMap), either loosely-coupled or tightly-coupled to a
1D river flow model, to determine patterns of fluvial flood
inundation in urban areas using high-resolution topographic
data. Applications of the basic model showed that even
relatively small changes in model resolution have
considerable effects on the predicted inundation extent and
timing of flood inundation. Timing sensitivity would be
