Possible channel routes (@ Nov 2006)

Shown below is the EA Lower Thames Strategy @ August 2009.

I find it hard to believe that Thames dredging for flood defence purposes has been deliberately abandoned by the EA in spite of clear recommendations from Clive Onion's Report (April 2004)

The Lower Thames Strategy

One of the largest urban areas in England and Wales that is not directly protected by flood defences.

Background

Teddington WeirThe Lower Thames Flood Risk Management Strategy is an integrated approach to managing flood risk in the area of the River Thames downstream of Datchet to Teddington lock. This part of the Thames floodplain is one of the largest urban areas in England and Wales that is not directly protected by flood defences.

The Lower Thames Strategy emerged after the flooding that occurred during January 2003 where 256 properties were flooded. Our aim is to take further action to reduce flood risk in this area.

Our integrated approach to managing flood risk is divided into two main components:

1. Floodplain Management Component

We propose to focus on land control: safeguarding flood flow and potential channel routes. Other approaches will include controlling development in areas that are prone to flooding. We also propose to improve public awareness of flooding and encourage the uptake of Floodline Warnings Direct, a free service that provides flood warnings via telephone, mobile, email and SMS text messages.

We plan to work in partnership with local authorities and other public bodies to develop emergency plans, local flood action plans and apply the best means available to make individual properties resistant to floods.

2. Engineered Component

This proposal is based on an engineered scheme option comprising of three flood diversion channels without the use of a form of dredging called riverbed re-profiling. The flood diversion channels will extend from Datchet to Walton upon Thames.

A review of the preferred options will be undertaken before they can be approved. At the same time, there will be a general provision of community-based measures to protect properties, based on earlier pilot schemes.
