SCOUR has been developed in Microsoft Excel for ease of use and transfer, and the data produced fits into the client’s systems for ease of reference.
The input is a dataset gathered from a combination of sources; water company data and desk-based interrogation of spatial data (using ArcGIS to support).
A simple checkbox user-interface element allows selections to be made that tailor the assessment to the reservoir in question. Classification is then automated within the tool.
The output is a risk category (‘Higher’, ‘Moderate’ or ‘Lower’) for each element (e.g. sediment, polluted sediment etc.). The tool also outputs an uncertainty category for each element using the same ‘Higher’, ‘Moderate’ or ‘Lower’ terminology.
Recommendations for mitigation/monitoring as a response to Higher risk or uncertainty can be made via tick boxes within the tool. These mitigation selections are manual, allowing for an expert review of the whole assessment to inform the recommendation.
