RIVER EDEN WEIR REMOVAL FEASIBILITY STUDY

LOCATION: River Eden, Cumbria

CLIENT: Eden Rivers Trust

We investigated the feasibility of several weir removals

within the Eden catchment in order to allow the free

movement of migratory fish and improve in channel

geomorphological conditions.

WHAT WE DID

• Fluvial Geomorphological Walkover of the study reach

• Hydraulic modelling to assess flood risk changes, and

changes to sediment erosion and deposition

• Development of post removal options.

BENEFITS TO THE CLIENT

• Multi-disciplinary team

• Technically robust solution.

HOW WE CAN SUPPORT YOU

• Hydraulic habitat assessment - qualitative assessment of the hydraulic

habitats that are present to form a baseline for WFD compliance.

• Fluvial Dynamic Audit - expert assessment of the present and likely

future dynamics of a water body linked to proposed interventions. This

in turn is linked to the need to demonstrate system stability in line with

the WFD requirements.

• Expert assessment of the impact of intervention on system hydromorphology

based on likely geomorphic change and natural river analogues.

• Quantitative 2D modelling of current and potential future hydraulic

habitats allowing comparison of the effects of intervention to be evaluated.

• Informed input to current restoration practice aligned with assisted

natural recovery principles.
