Aims and objectives

TRUck Vision

To develop a pilot project that highlights the role of natural riparian and floodplain intervention measures in managing flood risk in a discreet river catchment (the River Uck) through delivery of natural riparian and floodplain interventions such as wet woodland.

Subsidiary Vision

To document and provide evidence of the ecosystem service and biodiversity benefits accrued from applying a naturalistic landscape-scale flood risk management strategy to the Uck catchment.

Aims of the TRUck Project To form an innovative partnership between Sussex Wildlife Trust, Environment Agency, Woodland Trust and other partners that delivers the project vision. To deliver the aims of the Water Framework Directive and Ouse Catchment Flood Management Plan through natural floodplain enhancements in order to:

       * Help decrease velocities of flood flows by naturally increasing the in-channel and floodplain roughness of the Uck catchment. 
       * Help decrease unnecessary drainage and run-off from the catchment upstream of Uckfield.
       * Help increase the carrying capacity of washlands and the water storage capacity of the Uck.
       * Help all water bodies in the project area to achieve ‘good’ ecological and chemical status.

To engage the public, landowners, farmers and stakeholders in the process of promoting good practice catchment management.

To help others to have a better understanding of natural flooding and river processes and their implications for catchment management.


Objectives

Delivery

  • Identify suitable sites for Catchment Riparian Intervention Measures (CRIMs) and floodplain habitat and natural flood storage enhancements through the analysis, interpretation and collation of research and GIS data.
  • Produce a project plan outlining timings and focus areas for the project.
  • Support and facilitate the appropriate installation of CRIMs and other riparian enhancements such as floodplain woodland.
  • Set up an effective monitoring system along the river to assess the effects of TRUck project work.

Communication

  • Promote natural processes and naturalistic river and floodplain restoration methods and encourage others to implement them in appropriate locations.
  • Promote the TrUck project, its outputs and landowner offers (such as tree planting) through literature, events, communications and other media.
  • Provide an accessible and informative project ‘hub’ and public face for the TrUck project materials.
  • Hold stakeholder and community engagement events, and a project presence at other events where appropriate.
  • Produce a project summary using TrUck as a case study of best practice and lessons learnt from project delivery.
