In an area with longshore currents that flow from North to South groins tend to cause erosion on their northern (upcoast) side cause sand to accumulate on their southern (downcoast) side cause sand to . Conversely, a wider breaking angle, gentler beach slope, and lower wave height slows a longshore current's velocity. The net result of waves breaking at an angle to shoreline is to produce a weak current known as a longshore current (LSC). The size of the waves depends on the wind speed, the area over which it is blowing, and time. Generally, the speed of an oceanic wave that reaches the beach depends on the seafloor, shoreline features and the depth of water. antonyms and synonyms of abstain; paige colette crop flare white.

Much of the sediment reworked by waves and carried by longshore currents contributes to beaches. However, the beach behind the breakwater often grows at the expense of the shoreline that is not protected by the structure. Longshore drift is the movement of sediment carried along the shore by longshore currents. 1=beach, 2=sea, 3=longshore current direction, 4=incoming waves, 5=swash, 6=backwash As waves enter shallower water less than one-half wavelength depth, they slow down. Under rather quiescent conditions, longshore currents move only about 10-30 centimetres….
