摘要计算大断面沙质海滩的泥沙体积变化是一项困难而昂贵的工作。海岸线的变化可能是一个有用的量变化的指标，因为它可以快速且相对容易地远距离收集。本文综述了海岸线变化与地面体积变化高度相关的几项研究。我们还研究了三个新的数据集。在马萨诸塞州科德角，两个地点的海岸线变化时间序列和地面体积变化时间序列之间的相关系数分别为0.73和0.96。在阿萨蒂格岛，海岸线变化与地面体积变化之间的相关系数为0.71。在北卡罗来纳州的外滩，海岸线变化的时间变化和地面体积变化之间的平均相关系数为0.84。对于空间变异，平均相关系数为0.88。因此，海岸线变化是反映地面体积变化的一个有用的指标。
Abstract It is difficult and expensive to calculate changes in sediment volume for large sections of sandy beaches. Shoreline change could be a useful proxy for volume change because it can be collected quickly and relatively easily over long distances. In this paper, we summarize several studies that find a high correlation between shoreline change and subaerial volume change. We also examine three new data sets. On Cape Cod, Massachusetts, the correlation coefficients between the time series of shoreline change and subaerial volume change at two locations are 0.73 and 0.96. On Assateague Island, the correlation coefficient between along-coast variations in shoreline change and subaerial volume change is 0.71. On the Outer Banks of North Carolina, the average correlation coefficient between temporal variations in shoreline change and subaerial volume change is 0.84. For spatial variations, the average correlation coefficient is 0.88. It is therefore concluded that shoreline change is a useful proxy for subaerial volume change.
