Faecal bacteria exist in both free-living and attached forms in estuarine waters. The deposition of sediments can take faecal bacteria out of the water column and to the bed. The sediments can subsequently be re-suspended to the water column, which can then lead to re-suspension of the faecal bacteria of the attached forms back to the water column. Therefore, the fate and transport of faecal ba...

River ecosystems are often fragmented by artificial structures, such as weirs. For anadromous species, these structures can impede access to upstream spawning sites and ultimately lead severe population declines. This study focused on the freshwater migration of sea lamprey, Petromyzon marinus, an species threatened habitat fragmentation across its native range. To quantify cumulative impacts m...

In this study, enhancements to the numerical representation of sluice gates and turbines were made to the hydro-environmental model Environmental Fluid Dynamics Code (EFDC), and applied to the Severn Tidal Power Group Cardiff–Weston Barrage. The extended domain of the EFDC Continental Shelf Model (CSM) allows far-field hydrodynamic impact assessment of the Severn Barrage, preand post-enhancemen...

This paper outlines the potential threats upon sewerage systems arising from any increase in extreme rainfall events. The paper then describes the methodology and outcome of research undertaken by the Met Office on behalf of Severn Trent Water as the preliminary stage of an extensive project investigating changes in short period rainfall as a result of increasing greenhouse gases. Results and c...
