Overview
Diffuse nutrient pollution is a significant water quality issue in many groundwater-fed rivers in the UK. This work will help understand the impacts of in stream processes on nutrient cycling and the significance of hyporheic interactions in this type of environment. Fieldwork is being carried out on the River Leith in Cumbria, which is part of the River Eden catchment. Variability in parameters such as discharge and temperature on in stream nutrient processes will be investigated as these may important in determining long term impacts of climatic changes on nutrient cycling. The effects of in stream and hyporheic hydrological processes on the mobilisation of phosphorus will be investigated through speciation and water chemistry measurements.
