Abstract
A flash flood forecasting system has been developed which combines distributed modeling and statistical analyses to produce gridded forecasts of return periods. A distributed hydrologic model (DHM) coupled to a threshold frequency (TF) post-processor, DHM-TF, is currently being tested over a Maryland-centered domain, and has verified well against National Weather Service (NWS) flash flood warning areas and verification points. The prototype system is currently running in real-time at the NWS Office of Hydrologic Development (OHD), and efforts are underway to test DHM-TF at several NWS field offices.
