DESIGN FLOOD ESTIMATION FOR BRIDGES, CULVERTS AND CHANNEL IMPROVEMENTS WORKS ON SMALL RURAL CATCHMENTS

The note attempts to overcome the lack of consistency of prediction equations when calculating design flood values for small bridge, culvert or channel improvements in small rural catchments. Using multiple regression techniques and the "Food Studies Report" data from 42 catchment areas throughout the British Isles was used to develop a three-variable equation relating annual flood to area, soil type and rainfall. It can be shown that when compared with previous methods, statistically the equation gives better results throughout the country. (TRRL)
