Earth:List of tidal barrages
From HandWiki
Short description: none
A tidal barrage is an artificial obstruction at the mouth of a tidal watercourse, in contrast to a normal barrage along a river's inland course.
Purpose
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
