INCA-P (Integrated Catchments Model - Phosphorus dynamics)
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...

British Survey of Fertiliser Practice (1992-2015)
The British Survey of Fertiliser Practice (BSFP) is an annual survey based on the selection each year of a representative sample (c1500) of farms from mainland Britain. The survey is the primary source of information regarding the application of organic and inorganic...

FARMSCOPER (Farm Scale Optimisation of Pollutant Emission Reductions)
Farmscoper is a decision support tool that allows an assessment of the cost and effectiveness of agricultural mitigation methods on multiple pollutants. It incorporates meta-models of a number of different pollutant models which have previously been used for government...

Case Study
Case Study 2: Effectiveness of land management policies and agri-environment interventions for reducing pollutant loads and maintaining environmental quality at the national scale.
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)...

Case Study
Case Study 3: Costs and benefits of mitigation measures to reduce pollutant concentrations for the protection of drinking water in river-systems upstream of intakes.
Using the water quality models, SAGIS-SIMCAT and SWAT, a reduction in the risk of exceeding drinking water quality standards at a water treatment works intake was shown for nutrients and metaldehyde as a result of introducing farm measures. The costs of these measures...

High resolution water quality, hydrological and ecological monitoring in the river Eden catchment (2011 - 2015) [DTC project]
The River Eden Demonstration Test Catchment (EdenDTC) monitored water quality, hydrology and ecology across 3 sub-catchments to assess the effectiveness of diffuse pollution mitigation measures. The focus areas are in the Thackthwaite, Newby and Pow catchments. Each...

Case Study
Case Study 4: Effectiveness of pollution control measures under scenarios of future climate and land cover change at the catchment scale.
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...
