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:

Catchment Assessment components:
• 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.
• 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.
