beach depletion

beach depletion
  net loss of sand and/or shingle from a beach due to reduced replenishment while removal processes such as longshore drift continue unabated. Natural replenishment rates are thought to have slowed as sea-levels have risen, river loads have reduced, beaches have stabilized and humans have dredged offshore sediments.
