This study addresses the poorly known controls on the exchange of sediment between the shoreface and inner continental shelf under varying fair-and storm-weather conditions. The overall goal is to evaluate more complex interactions between waves, currents, suspended load and bedform characterisics to improve the understanding of shoreface erosion and accretion. Observations will be gathered from tripod-based flow meters, suspended sediment sensors and altimeters deployed at several sites from Virginia to Long Island. Measurements will be used to evaluate theoretical models of shoreface response and equilibrium adjustment. This information will be used to modify physical models.

这项研究解决了在不同的晴天和风暴天气条件下对岸面和内陆架之间沉积物交换的鲜为人知的控制。总体目标是评估波浪、水流、悬浮载荷和河床特征之间更复杂的相互作用，以提高对岸面侵蚀和增生的理解。观测数据将通过部署在从弗吉尼亚州到长岛的多个地点的三脚架流量计、悬浮沉积物传感器和高度计进行收集。测量结果将用于评估岸面响应和平衡调整的理论模型。该信息将用于修改物理模型。
