  • coastal recession caused by:
    Geology factors
    -> lithology and geological structure
    marine factors
    -> Long wave fetch, creating more destructive waves and strong longshore drift promoting erosion
  • dredging = removal of sediment from a beach
  • Human activity can increase rates of coastal recession by interrupting the operation of the sediment cell. The construction of major dams of rivers can trap river sediment behind the dam wall. This then starves the coast of a sediment source, leading to serious consequences.
