Radar-Based Flood Warning System Applied to Tropical Storm Allison

Regional scale flood modeling using NEXRAD rainfall, GIS, and HEC-HMS/RAS: a case study for the San Antonio River Basin Summer 2002 storm event

“…Since the blueprint paper by Freeze and Harlan (1969), flood modeling has greatly improved in recent years with the advent of geographic information systems (GIS), radar-based rainfall estimation using next generation radar (NEXRAD), high-resolution digital elevation models (DEMs), distributed hydrologic models, and delivery systems on the internet (Garrote and Bras, 1995;Bedient et al, 2003). There are, however, major issues that limit the accuracy in flood forecasts.…”

Assessment of a Regional-Scale Weather Model for Hydrological Applications in South Korea

“…Having been implemented in the U.S. and other countries, an advanced next generation Doppler weather radar system known as NEXRAD (WSR-88D) has become a popular way of monitoring weather systems. In terms of lead time for QPF, Bedient et al (2003) asserted that two or three hours were gained when NEXRAD was adopted in the flood warning system. These lead times can be used in the conversion process from the NEXRAD rainfall time series to a flood inundation map, especially for extreme flood events (Knebl et al, 2005).…”

The relationship between observation intervals and errors in radar rainfall estimation over the Indochina Peninsula

“…Such largescale estimations can still provide valuable information for flood forecasting and can be used as an input for streamflow simulation (e.g. Borga, 2002;Bedient et al, 2003).…”
