Tidal strait


A tidal strait is not technically a river, but a strait, connecting two oceans, or seas. Tidal straits are narrow seaways through which flow tidal currents. Tidal currents are usually uni-directional, but sometimes can be bi-directional. Frequently they are of tectonic origin. Currents in them develop due to elevation differences between the water basins at either ends.
Due to tides, sediments can collect in tidal straits.
