Single-basin barrage

Definition

A single-basin barrage is a tidal energy structure designed to harness the kinetic energy of tidal flows by creating a barrier that controls water movement within a single tidal basin. This system allows for the generation of electricity by utilizing the difference in water levels between the incoming and outgoing tides, enabling the capture of renewable energy from tidal movements. The components of a single-basin barrage typically include sluice gates, turbines, and a reservoir, which work together to optimize energy production.

5 Must Know Facts For Your Next Test

1. A single-basin barrage utilizes the natural rise and fall of tides to generate electricity, taking advantage of gravitational forces acting on water bodies.
2. Sluice gates play a crucial role in controlling the inflow and outflow of water, allowing for efficient energy capture during both high and low tides.
3. The design can significantly impact local ecosystems, as it alters water flow and sediment transport in the basin.
4. Single-basin barrages can be more cost-effective compared to multi-basin systems due to simpler construction and maintenance requirements.
5. Energy production from single-basin barrages is predictable, making it a reliable source of renewable energy compared to other forms like solar or wind.
