Case Study 7: Interpolation of model outputs and data from catchment to national scales and monitored to non-monitored sites
This case study uses a Dynamic Typology Tool (DTT) to combine spatially explicit datasets describing landscape character and management and identify homologous areas of agricultural potential, natural environment quality and risk. The DTT provides national coverage...

Major ion and nutrient data from rivers [LOIS]
Discrete data for major ions and nutrients in river water for 13 sites in the Humber catchment over the periods 1993 to 1997 and 1996 to 1997 and for 3 sites from the Tweed catchment over the period 1994 to 1997. Ions and nutrients measured were: Ammonia, Calcium (dissolved),...

Source apportionment of nutrient contributions to rivers in England and Wales modelled with SAGIS
Estimates of in-river concentrations (mg/l) and loads (kg/day) of nutrients to rivers in England and Wales from multiple sector sources, modelled with SAGIS (Source Apportionment GIS). The nutrients include nitrate (mg/l N) and ortho-phosphate (mg/l P); the estimate...

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...

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...
