GBV’s appraisal study is the first step in delivering flood protection to more than 15,000 properties along the River Thames between Datchet and Teddington – an area affected by major flooding last winter.
Scope of the River Thames Scheme appraisal study includes: outline design and costing of approximately 15km of flood relief channel, two motorway crossings, two rail bridges, 12 major river control structures and the material management associated with 140 hectares of landscaping
“In recent years we have experienced some of the UK’s worst floods, and we expect the extreme weather which caused them will become more frequent,” said GBV director Matthew Nott. “This makes the appraisal work a significant step in reducing risk to more communities along the Thames.”
Once funding is secured, this major engineering undertaking will see the creation of a new flood channel running parallel to the River Thames between Windsor and Shepperton. In addition the capacity of the weirs at Sunbury, Molesey and Teddington will be increased, and the Desborough Cut will be widened.
“To facilitate this we will be undertaking outline design, and a diverse range of environmental, geotechnical, hydraulic and economic assessments – drawing upon experience gained on the Jubilee River, Olympic Park, and Thames Tideway projects,” Mr Nott added.
