Abstract: Two widely used procedures by which radar- and gauge-derived rainfall can be optimally combined are those by the OneRain Corporation and the National Weather Service (NWS). The Florida Water Management Districts use rainfall data from the OneRain algorithm. On the other hand, Florida State University (FSU) has employed the National Weather Service scheme to create an historical precipitation database for the Florida Department of Environmental Protection (FDEP). Although the methodologies as well as the time and space resolution of each dataset differ, each is being used by their respective agencies to make water management and regulatory decisions. Thus, it is important to know how rainfall values from the two schemes compare to each other. This research statistically compares results from the two schemes, develops procedures so that both versions of data can be inserted into the WAM hydrologic model, and performs WAM model runs over various watersheds within the South Florida Water Management District (SFWMD) using both datasets.
