Reveted bank at Westborough post works

Project summary

Edit project overview to modify the project summary.

To take advantage of regular maintenance activities and utilise existing woody materials to reduce bank side erosion, whilst creating a better riverine habitat.

Objectives:

• Increase riverine diversity
• Stabilise eroding banks
• Reduce sediment input in to the river
• Provide fish refuge areas
• To explore environmental options whilst undertaking regular maintenance activities
• Bring multiple benefits through a joined up approach.
• Reduce ongoing maintenance cost
• Utilise existing materials
• Meet Water Framework Directive objectives

Phase 1 of the project delivered works along a section of bank 300 metres long, initially 40 meters have been reveted and a number of trees pinned. Phase 2 increased the length of works by a further 1.5km and included bank protection and tree pinning.

Monitoring surveys and results

This case study hasn’t got any Monitoring survey and results, you can add some by editing the project overview.

Lessons learnt

Edit project overview to modify the lessons learnt.

That by looking at our existing maintenance works; we can promote best practice by delivering cost saving initiatives that have a wider benefit on river ecology with minimal cost implications.
