9415946 Beach This award will complete a previously-funded project in which the authors built a new fiber-optic sensor and deployed it in two field experiments to monitor sediment transport in the swash zone. This award will support analysis of the data, to determine (1) the balance between erosion (by infragravity waves) and accretion (by incident band energy); (2) the role of microtopography, (3) the short-term distribution of resuspended sediment, and (4) the importance of supercritical flow. The results will contribute to understanding sediment erosion and redistribution on beaches. ***

9415946海滩 该奖项将完成一个先前资助的项目，其中作者建立了一个新的光纤传感器，并将其部署在两个现场实验中，以监测冲刷区的沉积物运输。 该奖项将支持数据分析，以确定（1）侵蚀（亚重力波）和吸积（入射带能量）之间的平衡;（2）微地形的作用，（3）再悬浮沉积物的短期分布，以及（4）超临界流的重要性。 研究结果将有助于了解海滩上的沉积物侵蚀和再分布。 ***
