A Conceptual Flash Flood Early Warning System for Africa, Based on Terrestrial Microwave Links and Flash Flood Guidance
A conceptual flash flood early warning system for developing countries is described. The system uses rainfall intensity data from terrestrial microwave communication links and the geostationary Meteosat Second Generation satellite, i.e., two systems that are already in place and operational. Flash flood early warnings are based on a combination of the Flash Flood Guidance method and a hydrologi...
متن کاملMerging multiple precipitation sources for flash flood forecasting
r a 200 .007 : +886 2 tu.edu.t Summary We investigated the effectiveness of combining gauge observations and satellite-derived precipitation on flood forecasting. Two data merging processes were proposed: the first one assumes that the individual precipitation measurement is non-bias, while the second process assumes that each precipitation source is biased and both weighting factor and bias pa...
متن کاملOptimizing Satellite-Based Precipitation Estimation for Nowcasting of Rainfall and Flash Flood Events over the South African Domain
The South African Weather Service is mandated to issue warnings of hazardous weather events, including those related to heavy precipitation, in order to safeguard life and property. Flooding and flash flood events are common in South Africa. Frequent updates and real-time availability of precipitation data are crucial to support hydrometeorological warning services. Satellite rainfall estimatio...
متن کاملNEXRAD Flood Warning System and Floodplain Library for Houston, TX
Early flood warning systems protect both infrastructure and human life by issuing accurate flood warnings to public and private entities, enabling emergency personnel to employ strategic procedures. One such system, the RiceU/TMC Flood Alert System (FAS) has proved effective at predicting flood levels along Brays Bayou for 30 major storm events since 1997, including T.S. Allison in 2001. The cu...
متن کاملAn Integrated Simulation and Distribution System for Early Flood Warning
This research presents an integrated system of computer software, networking and web-based display developed and deployed to allow drainage management authorities immediate access to results from the Weather Research and Forecasting (WRF) Hydrological Extension model, WRF-Hydro. Output data from the model are analyzed by a chain of GIS, database and web publishing tools to forge updated and rea...
