UKWIR’s Source Apportionment GIS Model (SAGIS): Version 4.0

Reference: 21/WW/02/13
ISBN: 978-1-84057-912-3
Published Date: 23/02/2021

This project has delivered an upgraded and enhanced version of SAGIS that will enable its continued use for investment planning, river basin management and novel research applications into the foreseeable future. The legacy VBA code has been migrated to the Python and C# programming languages and the host GIS platform upgraded from ArcMap 10.2 to ArcGIS Pro 2.3. The potential risks arising from the deprecation of VBA from the ArcMap platform have been removed. The code has also been transitioned into a formal professional software development environment following a standardised development approach, with key functional elements developed as modular components. Geoprocessing logging available in ArcGIS Pro provides modellers with direct information on the status of data processing tasks and support with process failure diagnosis. The new version represents a substantial and unprecedented technological leap and opens up the possibility of new and previously unconsidered development applications.

WFD Requirements for Lakes, Transitional and Coastal Waters: Source Apportionment for Nutrients and Priority Chemicals

Reference: 13/WW/02/4
ISBN: 1 84057 743 6
Published Date: 21/02/2021

The key objective of this project was to expand the existing SAGIS river tool for metals, organic compounds and nutrients to assess source apportionment in lakes, transitional and coastal waters (SAGIS-LaTraC) from all major point and diffuse sources, using available national datasets. Additional export load databases were developed for export of chemicals associated with lakes, transitional and coastal water bodies including inputs from wildfowl, anglers (i.e. ground bait) and boats (i.e. biocides). A simple lake model was developed within the SAGIS framework to estimate chemical input loads from rivers, local catchments and within lake sources and to simulate within lake concentrations. Input loads are also calculated for chemical loads to estuaries and coastal water. The SAGIS databases and visualisation tools were modified to include updated source apportionment information for lakes, transitional waters and coastal water bodies to support river basin planning and wider environmental management.

The main report presents the outline methodologies used for the SAGIS-LaTraC tool and an example from the upgraded tool with Appendix A providing a user guide for the SAGIS-LaTraC tool. The methodologies in the main report are expanded in Appendix B to give further information on the methods used to generate input loads for the model and simulate chemical concentrations and loads. The validation report, Appendix C, presents a comparison of model outputs with observed data and outputs from the QUEST estuary model.

Chemical Source Apportionment under the WFD

Reference: 12/WW/02/3
ISBN: 1 84057 637 5
Published Date: 21/02/2021

A GIS based tool (SAGIS)  to apportion loads and concentration of chemicals to WFD water bodies has been developed to support river basin planning by the UK Water Industry and the Environment Agency to identify effective programmes of measures, whilst maintaining the 'polluter pays principle', thus ensuring a fair proportioning of responsibility for improving water qualiry across all responsible sectors.
Chemical inputs for nutrients, metals and organic substances are separated into five sectors for point sources and seven sectors for diffuse sources. Outputs are also separated into these sectors to provide mapped (GIS) information of the apportionment of river concentrations and loads. SAGIS was developed using national datasets but the funtionality allows for the addition of better local information. The GIS software and databases are available with the project report (although subject to obtaining a licence for the flow data used by the tool).
