This report forms the Flood Study for Newport. It documents flood behaviour across the catchment for a range of historic and design floods. This includes information on flood discharges, levels, depths and flow velocities. It also provides estimates of the variation in flood hazard and hydraulic categories across the catchment and provides an assessment of the potential impacts of climate change on existing flood behaviour. The flood study comprises two volumes: Volume 1 contains the report text and appendices, Volume 2: contains all figures/maps.
