2017年飓风内特引发的风暴潮和海浪导致亚拉巴马州多芬岛出现大面积的过冲和淹没区域。过洗事件包括水和沉积物在海滩、沙丘和障壁岛系统上的输送。建立了七个样带，以测量风暴前和风暴后的调查概况。九波和水位传感器被部署在一个过洗区，并捕捉过洗条件，包括随时间变化的水位和波浪。所有样带都经历了调查的陆上区域的沉积物净损失以及一系列的洪水和沉积物过冲。结果突出了经验估计的局限性，以评估暴露的沙丘地区的过冲和淹没。
Storm surge and waves from Hurricane Nate in 2017 resulted in large overwash and inundation regions on Dauphin Island, Alabama. The overwash event consisted of the transport of water and sediment over the beach, dune, and barrier island system. Seven transects were established to measure pre- and post-storm survey profiles. Nine wave and water level sensors were deployed in an overwash region and captured the overwash conditions including time-varying water levels and waves. All transects experienced a net loss of sediment from the subaerial region surveyed and a range of inundation and sediment overwash. The results highlight the limits of empirical estimates for evaluating the exposure of backdune regions to overwash and inundation.
