A multi-year investigation to inform development of a new release regime from Thirlmere Reservoir to maintain the geomorphological and ecological functioning of the River Derwent and Bassenthwaite Lake SAC. Sediment transport data were collected using impact plates, particle tagging and turbidity probes. Restoration options were identified in a parallel project.
Development of a GIS-based method for mapping the risk of fine sediment accumulation within Irish rivers. The method calculates a range of geomorphological variables that can be used to inform catchment-scale restoration planning for fine sediment mitigation. Field-based validation of the output was conducted using site walkovers and sediment fingerprinting.
A multi-year sediment fingerprinting project to identify diffuse sources of fine sediment to important freshwater pearl mussel populations in three Scottish catchments. Seasonal sampling allowed for temporal changes in the relative importance of different sources to be understood. Results were used to recommend catchment-scale river restoration and land management measures.
