What's happening in USAR at the moment?
- Fowey Trac Case study: The Fowey Trac Catchment investigation aimed to fully understand the issues facing the Fowey catchment by combining in the ground monitoring with mapping and Modelling. Click here to find out more.
Westcountry Rivers Trust are partners in a consortium that has been awarded funding from the European Union’s Interreg 2 Seas Programme for the project USAR (Using Sediments As A Resource). A key aim of USAR is to develop ways of recycling this sediment and using it in innovative ways. Many of the other partners working on it in France, Belgium and the UK are focused on estuaries and harbours and are therefore mainly interested in recycling the sediment, accepting dredging as a necessary maintenance activity.
- Inventory catalogue of possible uses of sediment as a re-source and conditions, potential, limitations for use
- Recycling strategies for partner territories based on local potential for uses of sediment
- Pilot test one – blending organic sediments with agricultural waste for soil elevation and improvement s
- Pilot test two – geotechnical treatment of polluted sandy sediment to provide material for waterway embankments
- Pilot test three – use of marine dredged sediment in coastal saltmarshes as coastal defence
- Operational Sediment Management System: ICT tool for water managers to make business cases and management decisions for recycling of sediment.
- Liaison with Harbour Authorities across the Westcountry in order to determine their sediment quality, input, contamination levels and dredging needs in harbours linked to significant river catchments
- Evaluation of whether the novel approaches piloted in the Netherlands, Belgium and Brightlingsea Harbour would be applicable in the Westcountry
- Development of a ‘reduce and reuse’ sediment strategy for the Westcountry based on the requirements of Harbour Authorities across the region
- Monitoring and evaluation of partner pilots to develop a decision matrix of sediment recycling tools showing where and when they can be used, including reducing sediment input and contamination.
