      Guest post by Alex Terrell, who along with Andy Dawson wrote the series of “UK electricity ” guest posts Energy Matters published in Alex outlines an approach to constructing the Severn Barrage that replaces high-tech turbines with low-tech water wheels and which offers potential for increased output, lower costs and reduced storage requirements. The Severn Barrage is the name of a number of ideas for building a barrage from the English coast to the Welsh coast over the Severn tidal for dam ming or barraging the Severn estuary (and Bristol Channel) have existed since the 19th purposes of such a project has typically been one, or several of: transport links, flood protection, harbour creation, or tidal power.

A Severn Barrage. 3 Summary Following reports that a private consortium ha d met with the Prime Minister to discuss a new proposal for a tidal barrage in the Severn Estuary, the Committee launched an inquiry to examine the proposal in more detail and to encourage transparency and public debate.

The biological and chemical regimes of the Severn Estuary are severely stressed by its physical regime. Estuarine flora and fauna naturally adapt to habitat conditions.

Arrangements had been made to meet on the minor road at Old Passage near the village of Aust, within sight of the original Severn Bridge, built in particularly the Strategic Environmental Assessment of Severn tidal power.

DECC is grateful to all those who have contributed to the development of the evidence base. The key conclusions of the feasibility study are: • a tidal power scheme in the Severn estuary could cost as much as £34billion, and is. potential projects on the Severn, and in particular on the possibility of a Severn barrage.1 These developments are bringing into focus a longstanding debate over the potential for the Severn estuary to be used as a source of electricity generation.

In theory, the estuary contains natural conditions that could allow the generation. The retreat of the Severn Estuary Geomorphological evidence The character and response to natural forces of the bedrock cliffs on their margins demonstrates that (1) the inner Bristol Channel is undergoing enlargement, and (2) the Severn Estuary is retreat- ing (marine transgression) northeastward up the Severn Vale.

At £25 billion to build the barrage, all privately funded, we could have barrages for the same cost. An important part of this proposal is the use of bi-directional turbines. In the simplest case, a low to the north of the Severn Estuary produces westerly winds in the estuary.

Associated with low pressure areas are warm and cold fronts. Generally the air moves in a circular path around the low pressure centre, but in the areas between the warm and cold fronts the isobars tend to be straight giving winds of uniform speed and direction.

The Severn Barrage refers to a range of ideas for building a barrage from the English coast to the Welsh coast over the Severn tidal for damming or barraging the Severn estuary (and Bristol Channel) have existed since the 19th building of such a barrage would be a huge engineering feat, comparable with some of the world's biggest construction projects.

The River Severn (Welsh: Afon Hafren) is the longest river in Great Britain at a length of miles ( km). With an average discharge of m 3 /s (3, cu ft/s) at Apperley, Gloucestershire, it has by far the greatest water flow in England and Wales.

The Severn rises at an altitude of 2, feet ( m) on Plynlimon, close to the Ceredigion/Powys border near Llanidloes, in the Cambrian. The Severn Estuary (Welsh: Aber Hafren) is the estuary of the River Severn, the longest river in Great is the confluence of four major rivers, being the Severn, Wye, Usk and Avon, and other smaller rivers.

Its high tidal range, approximately 50 feet (15 m), means that it has been at the centre of discussions in the UK regarding renewable energy. am: Peter Hain has sent me this fuller explanation for why he is so keen to see a tidal barrage built across the Severn estuary: The Cardiff-Weston Severn barrage.

A mile barrage across the Severn is among five projects on a shortlist of potential schemes to harness the tidal power of the estuary published by the government today. The Severn Tidal Power Group (STGP) is a consortium of engineering and construction companies (Balfour Beatty, Taylor Woodrow, Sir Robert McAlpine and Alstom) formed in to work on making the Severn Barrage a reality.

They suggest that the Severn Barrage could be constructed in just six to eight years for £15 billion £20 billion. A total ofman years of employment would be.A gravel sample at Ripple (SO15 m), just north of the Severn-Avon confluence, is dom- D.
