Hydraulics Research Limited, funded by the Ministry of Agriculture, Fisheries and Food, are studying methods of improving flood discharge assessment with the co-operation of the Water Authorities of England and Wales. This interim report outlines the methods currently adopted by the Water Authorities in measuring flood discharges and the uncertainties associated with these measurements based on replies received by Hydraulics Research Limited. Proto-type and experimental work is highlighted that confirms the need for greater accuracy in flood flow measurement. A brief literature review relating to flow measurement and flood discharge is listed.
