River Engineering / Restoration & Sustainable Design
Edenvale Young undertakes a range engineering restoration and sustainable design projects. Edenvale Young has along established relationship with Cain Bio-engineering for the delivery of river restoration projects such as the Purbeck Keystone Water Level Management Plan and Skenfrith Weir restoration (see below). We are currently working together on the refurbishment of Purton Spillway for British Waterways board which involves both bio engineering and civil engineering design.
Since 2002 we have also carried out a large number of Flooding Pre-feasibilty and Project Apprisal Studies for Powys County Council, Caerphilly Borough Council and the Environment Agency. All of these projects have included hydrology, hydraulic modelling, optioneering, preparation of engineering costs and economic analysis. Both Powys County Council and Caerphilly Bourough Council have completed the installation of a number of schemes.Our most resent project is the Ribchester Pre-feasibility study for the Environment Agency.
Purbeck Keystone, water level management plan
Edenvale Young Associates Ltd was approached to act as part of a multi-disciplinary consortium to identify opportunities to manage water levels to restore floodplain grazing marsh on the River Frome in Dorset. The project primarily aimed to re-introduce favourable wetland conditions for breeding waders but also examined opportunities to enhance, maintain and manage the exisitng drainage network to the benefit and conservation of important ditch flora and fauna Read More...
Skenfrith Weir restoration
In 2000 the weir at Skenfrith was breached leading to a significant alteration in the alignment of the River Monnow adjacent to the village and the historic Norman castle. The mill at Skenfrith also dates back to the 15th Centaury and historic context of the weir is important. Edenvale Young was appointed to undertake a feasibility study for the restoration of the weir. Read More...
Knighton Project Appraisal Study
Edenvale Young was appointed by Powys County Council to undertake a flooding project appraisal study for the town of Knighton where approximately 50 properties are at risk of flooding from the River Teme and Wylcwm Brook in Knighton. The project appraisal study included hydrological and hydraulic modelling, preliminary engineering design, provision of engineering cost estimates, economic analysis (PAG 4) and a preliminary environmental assessment.

Sustainable Urban Drainage schemes
Recent projects involving sustainable drainage systems include: drainage impact assessment for Oxford Academy school, the preparation of an FRA for Cranfield Mill Student Accommodation in Ipswich which incorporated a green roof, rainwater harvesting; attenuation design for Llanrhaeadr-ym-Mochnant County primary school and the design of attenuation systems for for the A483 Trunk Road Improvements at Four Crosses and the Bronllys bypass in Powys.

Marden Mills chalk stream rehabilitation
As part of our long-standing relationship with Cain Bio-Engineering, Edenvale Young Associates Ltd was commissioned to provide hydraulic modeling support to a river restoration/rehabilitation scheme for a mill leat system at Marden Hill, Wiltshire. Read More...
Welshpool, Flooding Project Appraisal
Unnoticed by many the Ledan Brook runs through the centre of Welshpool. In common with many other urban rivers the brook has been gradually covered and culverted to accommodate residential and commercial development in the centre of the town. Following the preparation and submission of the pre-feasibility study in 2002 Powys County Council were given grant funding to undertake a full project appraisal to consider the issue of flooding in Welshpool.

Flooding Pre-feasibility Studies
In 2002 Powys County Council received funding from the Welsh Assembly Government to undertake pre-feasibility studies for 67 locations in the County subject to regular flooding from ordinary watercourses. Edenvale Young Associates undertook studies were to consider the technical, environmental and economic impact of flooding to local communities and make recommendatio for further funding of the WAG.

VW Audi Group, Cribbs Causeway, river diversion
Edenvale Young were comissioned by the VW Audi Group for the detailed design of a river diversion to facilitate the construction of a new showroom at Cribbs Causeway in Bristol. The scope of work included ISIS modelling to evaluate the flood risk to the site, preparation of drawings and specifications for hard and soft engineering works including a box culvert and bio-engineering works at the outfall.
