A tidal strait is a strait through which a tidal current flows. Tidal currents are usually unidirectional but sometimes are bidirectional. Tidal straits, though they are narrow seaways, are technically not rivers. They are frequently of tectonic origin. In them, currents develop because of elevation differences between the water basins at both ends.{{cite web | url=http://basin.earth.ncu.edu.tw/Course/SeminarII/abstract2013_1/20140117_2_3_tidal%20depositional%20systems%20in%20the%20rock%20record.pdf | title=Tidal depositional systems in the rock record: A review and new insights | publisher=basin.earth.ncu.edu.tw | date=April 9, 2012 | accessdate=27 May 2019 | author=Longhitano, Sergio G.; Mellere, Donatella; Steel, Ronald J.; Ainsworth, R.

Tides sometimes allow sediments to collect in tidal straits.{{cite journal |author=Longhitano |first=Sergio |last2=Steel |first2=Ronald J. |date=June 2015 |title=Deltas sourcing tidal straits: observations from some field case studies |url=https://www.researchgate.net/publication/282280995 |journal=31st International Association of Sedimentologists - Meeting of Sedimentology |access-date=27 May 2019}}{{cite journal |author=Rossia |first=V.M |last2=Longhitano |first2=S.G. |last3=Mellere |first3=D |last4=Dalrymple |first4=R.
