Groyne
From Coastal Wiki
Definition of Groyne:
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. Groynes can have special shapes and they can be emerged, sloping or submerged, they can be single or in groups, the so-called groyne fields. Groynes are normally built as rubble mound structures, but they can also be constructed in other materials, such as concrete units, timber, etc.
