• Description:
  "Sand dunes and sandbars which serve as natural protective barriers to ocean front structures on many beaches can undergo geological change due to wave action. Engineered structures such as concrete seawalls, stone revetments, and bulkheads can be damaged or destroyed by storm driven waves. Once these coastal defenses are eroded or destroyed by wave action landward buildings are vulnerable to wave attack. This paper focuses on the relationship of wave runup and setup to dune morphology and how wave forces directed at structures behind the dunes can be quantified. A comparison of wave forces to wind forces is made with the intention of demonstrating the dominance of wave action in producing damage to structures along the coast. Forecast techniques that allow wave action in the velocity zone to be integrated into operational forecasts are presented along with a case study of overwash during the 6 - 9 March 2013 Atlantic Storm"--Abstract.
