Groyne - Wikipedia
网页A groyne (in the U.S. groin) is a rigid hydraulic structure built perpendicularly from an ocean shore (in coastal engineering) or a river bank, interrupting water flow and limiting the movement of sediment. It is usually made out of wood, concrete, or stone.
Groynes - Coastal Wiki
网页A groyne is an active structure extending from the shore into the sea, most often perpendicular or slightly oblique to the shoreline. Adequate supply of sediment and existence of medium-strong longshore sediment transport are major conditions of …
What are groynes and how do they work? Made EASY
网页What is a groyne? A groyne is a structure built from the shore out into the sea to reduce longshore drift and prevent beach erosion. They are typically made from materials like wood, rock, or sometimes concrete and metal.
Groynes and their Classification – theconstructor.org
网页A groyne is a rigid hydraulic structure built either from the shore (in case of seas) or bank (in case of rivers) in order to dissipate the wave energy or to protect the banks from erosion by trap ping the sediments.
Groynes as shore protection - Coastal Wiki
网页A groyne redirects the longshore current, as it is constructed perpendicular into the longshore current. The groyne thus directs the current seawards along the structure, whereby an offshore-directed jet is generated.

网页2021年12月20日 · A field of groynes, on the other hand, is a series of smaller jetties extending into the surf zone and spaced at relatively short intervals along a beach (see Fig. 10.13). They can be very effective in reducing the existing longshore sediment transport rate 2 along a coast.
Groyne - Coastal Wiki
网页a groyne is normally a straight structure perpendicular to the shoreline. Groynes work by blocking (part of) the littoral drift, whereby they trap/maintain sand on their upstream side.
