| 摘要： | Beneficially using dredged sediment to nourish the near-shore region of the beach is a common practice that keeps the material in the littoral system and may extend the life span of traditional sub-aerial beach nourishments. Dredged sediment with slightly more fine material than is allowed for sub-aerial beach placement is often able to be placed in the near-shore, which allows natural processes to winnow the fine grains from the placed material. Near-shore nourishments constructed as a mound or bar are often referred to as near-shore berms and can reduce the wave energy impacting the shoreline by breaking waves farther offshore (McFall et al, 2021). The reduced wave energy on the lee side of a near-shore nourishment often provides an area conducive for capturing the long-shore transport and inducing shoreline accretion (McFall et al., 2017). The longevity of the near-shore nourishment is highly dependent on several factors including the wave climate, placement depth, and placed volume (Bain et al., 2021). To improve the understanding of the morphological evolution of a near-shore nourishment and beach response at an erosional hot-spot, a near-shore nourishment project was extensively monitored in Harvey Cedars, New Jersey. Knowledge gained from this monitoring will support future projects and advance the practice of near-shore nourishment. |
