AB: Analyses of radar rainfall estimates from the WSR-88D radar network are presented for a sample of major flood events in the US. The framework for radar rainfall analysis is the HydroNEXRAD system and analyses highlight the utility of radar rainfall estimates for a diverse range of flood hydrology applications. The sample of flood events focuses on regions of the US with large flood potential, including the Edwards Plateau of Texas, the central Appalachians and urban watersheds of the eastern US. The basin scales of interest range from less than 10 sq. km. to more than 10,000 sq. km. We examine errors in radar rainfall estimates from the perspective of extreme flood-producing storms. Analyses for the Edwards Plateau of Texas focus on major storm events in June 1997 and July 2002. In the Delaware River basin, analyses center on a sequence of record and near-record flood events in September 2003, April 2004 and June 2005.
