What is the Bridgewater coastal barrage?
A tidal barrage at Bridgwater and dredging on the Somerset Levels form part of a £100m plan to combat flooding, the BBC understands. The plan includes a barrage across the River Parrett downstream of Bridgwater, to hold back the highest tides – but estimates it would be 15 years before that would be built.
Why did the River Parrett flood?
The extensive floods were caused by a combination of human and physical factors: • A prolonged period of extremely wet weather – in southern England it was the wettest January since records began in 1910 – saturated the ground and led to frequent over-topping of the rivers Tone and Parrett creating a huge lake covering …
How does a barrage work?
The barrage reservoir is filled up passing through turbine tunnel. This flow of water spins the turbine and generates electricity. This formation of barrage is a one-way system, i.e., one can only utilize the energy flowing through high tide to tidal basin which makes it restricted to about 6 h per tidal cycle.
What is barrage in tidal power plant?
A Tidal Barrage is a type of tidal power generation scheme that involves the construction of a fairly low walled dam, known as a “tidal barrage” and hence its name, spanning across the entrance of a tidal inlet, basin or estuary creating a single enclosed tidal reservoir, similar in many respects to a hydroelectric …
Can you swim in the River Parrett?
A number of amenities have been added to the riverside at Langport including fishing platforms, and pontoons for access to the water for swimmers, boats and canoes.
What river runs through Bridgwater?

What is tidal barrage system?
A tidal barrage consists of several tidal turbines placed along a dam-like structure. The dam walls prevent any water flow along the structure, so all the energy of the water currents is forced to pass at a higher pressure through the turbine locations only.
Why barrages are built?
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross.
Does barrage produce electricity?
What is the Bridgwater tidal barrage and dredging plan for Somerset Levels?
A tidal barrage at Bridgwater and dredging on the Somerset Levels form part of a £100m plan to combat flooding, the BBC understands. Villages on the Levels have been cut off for more than two months following the wettest winter on record.
What is the Bridgwater tidal barrier and downstream defence?
The Bridgwater tidal barrier and downstream defence works are important to support the sustainable growth and development of the town and to build business confidence. The barrier will be a large structure across the River Parrett between Express Park and Chilton Trinity.
When will Bridgwater’s barrier be built?
The flooding in early 2014 led a partnership of key authorities to prepare a ’20 Year Flood Action Plan’. The Plan has a clear objective of building a barrier to protect Bridgwater by 2024.
How feasible is a lagoon across Bridgwater Bay?
• a lagoon across Bridgwater Bay (£17.7bn estimated capital cost) is also considered potentially feasible, as is the smaller Shoots barrage (£7bn). The Bridgwater Bay lagoon could produce a substantial energy yield and has lower environmental impacts than barrage options. It also offers the larger net gains in terms of employment;
