River and Floodplain Enhancement Feasibility

The National Trust is a custodian of significant lengths of river across the country and is committed to managing them sustainably. The team at Lytes Cary commissioned FLOW CIC to conduct River Restoration Feasibility Studies and develop Concept Designs for two watercourses: the River Cary and Park Brook.

Both the River Cary and Park Brook have degraded habitats, primarily through historic land drainage practices. FLOW CIC were commissioned alongside Hydro-Morph Ltd. to carry out all relevant surveys and produce concept designs for river and floodplain enhancements.

Our approach to River Restoration Feasibility

Working closely with Jane Moon from HydroMorph Ltd. we carried out a detailed baseline assessment including: River Drone Survey, Topographic Survey, Soil Analysis, Water Vole & Otter Survey, River Condition Assessment, UKHab assessment and Geomorphological Baseline Study. In consultation with the client, we defined a small number of quantifiable project objectives for which potential restoration measures were scored against.  Baseline information and potential river and floodplain restoration options were summarised in a feasibility report.

The proposed options were presented to the client, and the preferred measures were developed into concept design drawings that could be used for future funding applications.

Positive Outcomes for the River Cary

River restoration options for the River Cary include in-channel habitat enhancements and lowering historic spoil banks to increase lateral connectivity. The works are likely to have a positive impact on fisheries, aquatic ecology, and the Water Framework Directive (WFD) status. An ambitious realignment of Park Brook has been proposed, which will create a mosaic of seasonally wet habitats and enhance biodiversity, as well as improve water quality. For areas away from the two watercourses, we have proposed a mosaic of species-rich grassland, scrub succession and tree planting to provide a variety of habitats. Options for extending the existing footpath network are provided, enhancing access for site users.
