Hydraulics Research Ltd are studying methods of improving the assessment of flood discharge on behalf of the Ministry of Agriculture, Fisheries and Food. The research is being carried out with the co-operation of the National Rivers Authorities in England and Wales, and includes the analysis of existing flood flow data, and the development of new methods for assessing flood discharge. This report describes modifications to and check calibrations of a peak velocity meter designed to measure flow velocities on flood plains and which can be interrogated after the passage if a flood. The report also describes the site installation of the meter
