TRANSCRIPT
Overview of the Water Quality Catchment Assessment approach
Angela Bartlett Westcountry Rivers Trust
INTRODUCTION
• Existing water quality pressures in a catchment. • Water quality parameters failing in a site of
conservational and/ or human resource interest. • Assessment of pressures within the catchment. • Spatial analysis of pollution risks and sources
within the catchment.
What can Water Quality Catchment Assessments be used for?

Integrated Catchment Based Approach
• Data and evidence
• Catchment scale analysis
• Stakeholder dissemination
• Local knowledge
• Detailed Spatial Pollution Risk Analysis
• Integrating with Existing Knowledge
• Making Information Accessible
• Provide tailored intervention strategies

Catchment Assessment components:
POLLUTION RISK ANALYSIS
• Assessing & mapping outputs from existing models
• E.g. SAGIS, SIMCAT,
PSYCHIC & SCIMAP

INTEGRATING WITH EXISTING KNOWLEDGE • Important part of the Catchment
Assessment process • Engaging with relevant contacts such as
CSF officers and CaBA hosts
Provides a ‘reality check’
Mapping current delivery via CSF and ES schemes.

Providing an intervention strategy
• Uses assessment of outputs from existing models and data.
• Identify areas where interventions should be targeted for water quality.
• FARMSCOPER modelling for on-farm mitigation methods
and pollution reduction estimates.
Map identifying areas for targeted delivery based on pollutant source risk and current interventions in the Camel catchment.
Example evaluate data sheet for the FARMSCOPER model.

‘Reality check’ Intervention strategy for use on the ground
• Collaborative approach to catchment management to ‘reality check’ modelled outputs.
• Use visualisation techniques to turn data into evidence.
• Can identify areas for target management.
• Feedback
Areas to work on: • Accessibility of models, data and reports.
