What is the platform for?

Land and water managers are facing a challenging situation trying to manage our catchments and water resources to deliver a complex mix of competing demands. These include targets for improving water quality for multiple pollutants, food security, carbon capture for climate change mitigation, and biodiversity. The Catchment Management for Water Quality project’s ‘community of practice’ have identified key issues which has ensured all the resources made available on this Platform are of practical help in answering real world problems.

While the data and modelling resources on the Platform are freely available from their developers, the material can be hard to track down and may not always be well described. By bringing them together in one place and demonstrating how they can be used to answer a set of key water quality issues, CaMMP provides practical support for a wide range of organisations involved in catchment management from local to national scale.

Open Access Tools

Get the CaMMP models and tools

The Catchment Management for Water quality project supports this web-based data and modelling platform to allow the discovery and download of the major modelling and data resources assembled by the project. The intent is to improve communication between the users and developers of models (and datasets), and to provide open access to tools which can answer emerging issues related to water quality modelling. 

Details of the models and tools used in CaMMP can be found in the CaMMP model catalogue. The links below will take you to the developers and providers of the models and tools so you can arrange to get a copy for your own use.

1: FARMSCOPER   (Farm Sale 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 policy support at national scale.

2: INCA-Pathogens  (Integrated Catchments Model – Pathogens)

INCA-Pathogens is a processed based dynamic model representation of terrestrial system for pathogen dynamics and instream pathogen dynamics and interactions with bed sediment stores. It is spatially semi-distributed.

3: SWAT  (Soil and Water Assessment Tool)

SWAT 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, and pesticide yields within catchments.

4: QUESTOR  (Quality Evaluation and Simulation Tool for River Systems)

QUESTOR represents a river as a series of river reaches within which physical, chemical and biological processes operate. The model is used to simulate water quality in rivers especially eutrophication for scenario analysis.  Questor helps catchment managers assess the impact of their actions on river discharge and water quality.

5: INCA-N  (Integrated Catchments Model – Nitrogen dynamics)

INCA-N operates at a daily time step, tracking the stores and fluxes of water, nitrate and ammonium 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 sub-catchments.

6: LUCI  (Land Utilisation & Capability Indicator)

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, and habitat provision. Trade-offs between outputs for the individual ecosystem services are modelled and mapped, with an option for the user to preferentially weight services of higher importance.

7: 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 sub-catchments.

8: SAGIS  (Source Apportionment GIS)

SAGIS analyses sources of chemicals at the river basin scale and identifies measures to improve river, lake and estuary water quality. National data on the source of chemicals from a range of point and diffuse sectors are processed to create inputs to the water quality model SIMCAT, and the outputs are used to create databases and visualisations of predicted apportioned water quality.

9: SEPARATE  (Sector Pollutant Apportionment for the Aquatic Environment)

SEPARATE is a national scale nutrient and sediment source apportionment screening tool for England and Wales. It provides apportionment of annual loads of nitrogen, phosphorus and fine-grained sediment, from both diffuse and point sources to rivers at Water Framework Directive waterbody scale.

10: DTT  (The Dynamic Typology Tool)

The DTT combines spatially explicit datasets describing landscape character and management and identifies homologous areas of agricultural potential, natural environment quality and risk.  The DTT provides national and local output and can aid identification, targeting and prioritisation of land-use opportunities for management of water quality.

Catalogue Resources

CaMMP Model, Data and Case Study Catalogues

One of the primary objectives of the Catchment Management for Water Quality project is  to provide better access to data and modelling resources through CaMMP. Gathering a range of important resources in one place and making them available in a systematic and transparent way will allow stakeholders and practitioners to explore tools and approaches enabling more integrated modelling to deliver holistic solutions for multiple pollutants, services & policies. The models, datasets and case studies provided on CaMMP have been entered into searchable catalogues to make the process of discovery and selection more straightforward.

If you are not sure of the resources you should be seeking in the catalogues, please visit guidance in selecting CaMMP resources.

The CaMMP Model, Data and Case Study Catalogues are hosted on the UK Centre for Ecology and Hydrology's servers. When you click on the buttons below, the UKCEH catalogue site will open in a new tab (and this tab will remain open). When finished in the catalogue, close the UKCEH catalogue tab and you can resume your session here.

Case Studies

Guides to potential benefits 

A key activity of the Community Forum has been the identification of important current and emerging questions relating to policy development and implementation in the area of water quality management. Data and models selected to explore these questions have been prioritised for availability on CaMMP.  The potential benefits of using these data and models can be demonstrated through a series of case studies.

These case studies, a resource for the stakeholder community, are available below complete with video interviews with members of the project team and stakeholders.

Case Study 1

Multiple pollutant and ecosystem services responses to land management policies and agri-environment interventions at the farm to catchment scale

Case Study 2

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

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.

Case Study 4

Effectiveness of pollution control measures under scenarios of future climate and land cover change at the catchment scale

Case Study 5

Uncertainty in ecological responses to water quality control measures at the river basin scale

Case Study 6

Effects of input data quality and quantity on evaluation of land management policies and agri-environment interventions at catchment to national scales

Case Study 7

Interpolation of model outputs and data from catchment to national scales and monitored to non-monitored sites
