Cover Story: This study examines the accuracy of flood extent simulations in five U.S. watersheds using the ARC and Curve2Flood topobathymetric flood mapping tools. At each site, we model floods for combinations of four return periods, four digital elevation models, and two stream networks. The experiments are notable because they build on an operational global hydrology model, so subsequent model versions can provide both historical reference and forecasted flood extent products. Accuracy was measured against USGS reference maps using the F-statistic. The largest improvements in accuracy occurred when both the DEM and hydrography datasets were from higher-resolution sources. In some cases, the effect of a coarser but bare earth DEM was more important than higher spatial resolutions. Stream locations were most important at low return periods. View this paper
