Description: Technical note
General: An important consideration in the functional design of any groin system is the possibility of increased erosion downdrift of these structures. In order to avoid the abrupt change in the shore alignment that may result in erosion of the downdrift beach, transitional groins (groins of gradually reduced lengths) may be used. A method for the design of a groin system transition that involves groin shortening has been used by the U.S. Army Engineer District, Wilmington (1973). Kessner (1928) conducted model studies on groin transitions and more recently Bruun (1952) applied the principle of groin shortening at the end of groin systems.
