WitrynaLongshore transport moves a tremendous amount of sediment along coasts (both oceans and large lakes) around the world, and it is responsible for creating a variety of depositional features that we will discuss in section 13.4. Witryna3 sie 2024 · Groynes in the water form beaches, reduce beach erosion caused by longshore drift where it is the dominating mechanism, and aid in beach replenishment. There is also frequent cross-shore movement, which, if it is longer than the groyne, reduces its efficiency.
