SAGIS was developed for UKWIR, with support from the Environment Agency, SEPA and Natural England, to analyse sources of chemicals at the river basin scale and identify measures to improve river, lake and estuary water quality. National data on the source of chemicals...

LUCI explores the capability of a landscape to provide a variety of ecosystem services, such as agricultural production, flood and diffuse pollutant mitigation, carbon sequestration, habitat provision etc. The model is a second generation extension and accompanying...

INCA-P operates at a daily time step, tracking the stores and fluxes of water, sediment, dissolved and particulate P in both the land and in-stream phases of a river catchment. The model is spatially ‘semi-distributed’: the water course is split into reaches with associated...

National scale nutrient and sediment source apportionment screening tool for England and Wales developed originally as part of Defra project WQ0223 (Developing a field toolkit for ecological targeting of agricultural diffuse pollution mitigation measures). SEPARATE...

Despite the uncertainty in future climate and land use, large-scale measures put in place today to improve water quality are likely to remain effective in the future in northeast Scotland. Dynamic models can provide useful indications of the likely lag time between...

The impacts of the suite of Countryside Stewardship options were reductions in national agricultural pollution of over 6% (nitrate) and 10% (phosphorus). Accounting for non-agricultural sources of pollution reduced the net overall impact of the options to 4% (nitrate)...

This case study examines potential trade-offs and co-benefits for a suite of ecosystem services at the farm to catchment scale that may be potential ‘by-products’ of an agri-environment scheme designed to reduce total multi-pollutant loads entering watercourses.
