The Environment Agency of United Kingdom (EAUK) is planning to undertake the Thames Flood Defence Scheme project at Thames River coast in London, the UK.

It will include the construction of footpaths, reed beds, widening of Desborough Cut by 3m to 4m on the southern bank, bridges, culverts, weirs and other related infrastructure.

Subject to funding approvals, the scheme will be carried out in two phases.

The first phase includes developing a funding strategy for the scheme; a hydrology and modelling study; ecological surveys of the River Thames and specific sites; the installation of property level products in some homes; major incident planning to improve preparedness and response to flooding; increasing the flow capacity of Sunbury, Molesey and Teddington weirs and obtaining planning consents for the enabling works on the weirs securing government assurance and approvals.

The second phase includes detailed design of the scheme; securing full, detailed planning permission and other consents for the work; building all three sections of the flood channel and associated structures, and increasing the capacity of Desborough Cut.
