Development of a Weather Radar Based Rainfall Forecasting Technique for Real-Time Operational Use
The National Rivers Authority has responsibility for water resources, water pollution control and flood defence and a number of associated environmental matters in England and Wales. One of the Authority’s flood defence aims is to “extend flood warning systems and improve responses to flood emergencies”. The rivers in England and Wales are relatively short when compared with many continental rivers although many respond fairly slowly to rainfall. However, in the south of England particularly, but not exclusively, convective summer storms can generate very high rainfall intensities and cause flash flooding. This is a special problem in the London area due to the immediate run-off from paved areas. The rate of development of such storms and their very local nature, have made flood forecasting under these conditions imprecise in the past.
