A tidal barrage is a dam-like structure used to capture the energy from masses of water moving in and out of a bay or river due to tidal forces. [1] [2] Instead of damming water on one side like a conventional dam, a tidal barrage allows water to flow into a bay or river during high tide, and releases the water during low tide.
The Nampho Dam or West Sea Dam, also known as the West Sea Barrage or West Sea Lock Gate, is a tidal barrage located 15 km west of the special city of Nampho, North Korea. It is a large, eight-km-long system of dams, three lock chambers, and 36 sluices , allowing the passage of ships up to 50,000 tons.
Tidal range, harnessing potential energy from the height difference between high and low tides, impounding water in a tidal barrage or lagoon. Tidal stream , harnessing kinetic energy of the tidal streams and currents flowing around the coastline using free-stream turbines.
The common primary functions of a barrage are: Increase the depth of a river (similar to a weir) Maintain a separation between fresh and salt water; Reduce the risk of tidal flooding up the river; Secondary functions may include: Tidal power generation; Artificial whitewater leisure centres; Form a Coastal reservoir

Unlike historical tide mills, which could operate only on an ebb tide, the Rance barrage can generate electricity on both flows of the tide, or it can be used for pumped storage, depending on demand. A less intrusive design is a 1MW free-standing turbine, constructed in 2007 at Strangford Lough Narrows; this site is close to an historic tide mill.
