Role of Human Activities: Coastal Construction
Seawalls and bulkheads can contribute to incomplete storm beach recovery by limiting the onshore transportation and deposition of sand. The structures can decrease the effective width of dry beach needed for eolian transport and prevent the progressive transfer of sand from the forebeach to the backbeach. As a result of this interference with the sand budget, natural dune restoration is prevented or prolonged and the total beach recovery is either incomplete or delayed.
