WebHard engineering coastal management involves building artificial structures which try to control natural processes. Hard engineering approaches to coastal management tend to be expensive, last only a short amount of time, are visually unattractive and unsustainable. They often increase erosion in other places further down the coast. WebLongshore Drift. The transport of sand and pebbles along the coast is called longshore drift. The prevailing wind (the direction the wind ususally blows from) causes waves to approach the coast at an angle. The swash …
WebSince longshore drift causes sediment to move along a coast in the same direction as the wind, beaches can lose sand. To prevent this, groins are installed to trap the sediment from moving along the beach. As a result, sand piles up on one side of the groin, making the boundary between land and water different on both sides of it. WebThe side of the groyne facing the longshore drift blocks the movement of sediment and it is deposited. The side protected from the waves is starved of sediment because waves cannot reach it to deposit load. …
