BUDS Phase 1 Cover

Beneficial Use of Dredging in the Solent Project (BUDS)

There has been a strong desire amongst Solent Forum members to find solutions to the many barriers which are preventing the effective use of dredged material to augment Solent intertidal sites and, hence, to provide other benefits associated with such restoration work (especially enhanced coastal protection). The Forum’s role will be to launch the first phase of the project and facilitate future communications. For more detailed information please download the BUDS Terms of Reference.

Project Aims and Benefits

The Solent Forum now seeks to build on past work and lead on the development of a proposal that will:

'Bring about beneficial use of dredging within one or more Solent sites, using an incrementally phased approach to scope and cost sediment sourcing and sediment receiver sites, building a system of protocols and guidance.'

More specifically the project will aim to:

This work should build on a wealth of information much of which relates to the Solent including amongst others work from the River Hamble Harbour Authority, the University of Southampton and Lymington Harbour. It is important that the work does not replicate previous work and that the budget is used to further the delivery of beneficial use projects.

It will only be possible to make real advances in the Solent if the benefits of the re-use of dredging material is really understood and costed, and these benefits are aligned to objectives of regulatory bodies and coastal managers.


Project Phases

The project comprises three phases. Download the project brief.


Phase 1 - Project Scoping and Partnership Working – COMPLETE

Phase 1 of the project was conducted by ABPmer. This phase included a Stakeholder Workshop. The main areas of work included:

  1. Literature review of previous Solent work, issues, challenges and constraints, including understanding of national context and drawing upon past review work.
  2. High level review of beneficial use projects in Solent. Some detail required on criteria for assessment, and how to measure efficacy, using best practice and lessons learnt of projects elsewhere.
  3. Create a high level strategic GIS planning map of Solent dredge locations and disposal sites and areas of potential value for recharge work.
  4. Building a stakeholder network for the exchange of information (the project group is the core). Survey relevant Solent Authorities and stakeholder network for potential donor material and receiver sites.
  5. High-level feasibility study including cost benefit analysis and costing of proposals to undertake beneficial use project (highlighting the range of beneficiaries).

Phase 2 – Feasibility and Stakeholder Working – CURRENTLY BIDDING PHASES 2 and 3

Feasibility Study and Detailed Cost Benefit

Develop options for the Solent for a project(s) for beneficial use within a set time period and for preferred options to develop full feasibility plans for actual use of dredging at some key sites. To consider whether a scheme may be a one off or one that can be repeated. This study would detail exact timings and costs of sources of sediment to match with receiver site needs. It would identify funding sources for complete projects. The beneficial costs will be firmed up so as to fully calculate cost benefit. Licences and permissions to be fully scoped ready to obtain. EIAs conducted.

Stakeholder Working

This will involve working with stakeholders to develop strategic guidance and s protocol. It will be led by the Solent Forum building on from Phase 1 work, using workshops and stakeholder meetings. Specifically it will:


Timetable: September 2018 to March 2020.


Phase 3

Beneficial use of dredgings projects in the Solent.
