Case Study
Case Study 5: Uncertainty in ecological responses to water quality control measures at the river basin scale.
QUESTOR modelling shows that all the mitigation methods applied can reduce the amount of Chlorophyll-a predicted to occur in the river. The extent of the reduction is different depending on the data used to drive the QUESTOR model. The effect of increasing the shading...

SAGIS (Source Apportionment GIS)
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...

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 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...

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...

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...

Hourly physical and nutrient monitoring data for the River Enborne, Berkshire (2009-2012)
This data set comprises of hourly physical and nutrient monitoring data of the River Enborne near Brimpton (National grid reference SU568648), from November 2009 to February 2012. Parameters measured are total reactive phosphorus, nitrate, conductivity, temperature,...

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)...

SWAT (Soil and Water Assessment Tool)
SWAT is the product of over 40 years of research and is subject to ongoing development. The model is designed to simulate the effects of changes in land management practices, land use and climate on surface water and groundwater quality and quantity, sediments, nutrients,...

Field measurements of major ions, phosphorus, nitrogen fractions, alkalinity and pH (2010-2015) [Wensum DTC]
Field measurements of major ions, phosphorus, nitrogen fractions, alkalinity and pH from the Wensum Demonstration Test Catchment, in Norfolk, measured between 2010 and 2015. Water samples are collected at 7 sites (aka monitoring kiosk A, B, C, D, E, F, M) in this catchment...
