- Restore an engineered, uniform channel to favourable condition using cutting-edge river restoration techniques;
- Incorporate key ‘Water Framework Directive’ features using a sustainable design; and
- Sinuous channel plan-form, variable bed profile, variable substrate types & distribution, variable marginal zones, bio-diverse riparian zone including ponds and wetlands.
The project provided a demonstration site for a suite of restoration techniques including composite geotextile bank revetments.
Site-won willow logs and coppiced hazel mattresses were used to narrow the channel and create a sinuous, flood-friendly angler access.
The creation of in-channel woody debris features, off-line marginal ponds and wetland habitats for invertebrates, amphibians and BAP species were key bio-diversity objectives.
“The in-channel works and marginal wetland ponds have added a new dimension to chalk stream restoration. Biodiversity gains have been significant”
