This thesis tests the critical source area (CSA) hypothesis that heterogeneities in hydrological connectivity and pollutant mobilisation result in limited areas of a catchment which export disproportionate pollutant loads. This hypothesis was tested at the field and catchment scale over a 3 year period at a field site in Hillsborough, Co. Down, and 3 catchments in Co. Down and Co. Louth. At the field scale, this thesis demonstrated that the CSA hypothesis may be suitable to predict loads for certain fractions of P, yet may not be suitable to predict the loads of nitrogen and particulate P. Research at the catchment scale used sediment tracing of sediment sources to validate CSA modelling. Results indicated that no variation in median land u...
