Funds are provided for the project to investigate the hydrodynamics and sediment transport processes associated with migrating ridge and runnel systems. Novel insitu techniques developed from wave flume experiments will be combined with remote sensing methods to quantify sheet flow, suspended sediment transport, and morphodynamic response in a ridge and runnel system in Rehoboth Beach, Delaware. Results will be used to test the hypothesis that sheet flow processes dominate ridge and runnel migration, and to develop a comprehensive understanding of the morphologic evolution of these systems from inception through attachment to the beach. This research may lead to improved management of beach erosion and recovery. The project will support a PhD student (with recruitment targeted towards underrepresented minorities) and two undergraduate students. The PIs will construct and train teachers to operate a portable flume for use in three Texas high schools participating in the ?Beach in a Classroom? program. Project results will be incorporated into public outreach activities in Texas and Delaware.

为该项目提供资金，以研究与迁移山脊和沟道系统相关的流体动力学和沉积物运输过程。波浪水槽实验开发的新型原位技术将与遥感方法相结合，以量化特拉华州里霍博斯比奇的山脊和沟渠系统中的片流、悬浮沉积物输送和形态动力学响应。结果将用于检验席流过程主导山脊和沟道迁移的假设，并全面了解这些系统从开始到附着于海滩的形态演变。这项研究可能会改善海滩侵蚀和恢复的管理。该项目将支持一名博士生（针对代表性不足的少数族裔招生）和两名本科生。 PI 将建造并培训教师操作便携式水槽，供参加“课堂海滩”项目的三所德克萨斯州高中使用。程序。项目结果将纳入德克萨斯州和特拉华州的公共宣传活动。
