A Method to Assess Localized Impact of Better Floodplain Topography on Flood Risk Prediction

Figure 4

Map of individual subreaches and their floodplains, that is, regions of assimilation (colors are at random). Subreaches of hydraulic complexity (defined as >2σ from the kinematic wave form; see text for details) are depicted with a red outline and annotated. Note that the flooded area shown for each subreach is based on a 1 : 10,000 year flow return flood simulation, overlain as a blue outline on the SRTM topography in Figure 1. Photos are taken from Google Earth.
