Collaborative Research: Ridge-runnel post-storm beach recovery - hydrodynamics, sediment transport and morphodynamics

为该项目提供了资金，以调查与迁移的山脊和隧道系统有关的水动力学和沉积物输运过程。新的原位技术开发的波浪水槽实验将与遥感方法相结合，以量化片流，悬浮泥沙输运，并在一个山脊和隧道系统在雷霍博斯海滩，特拉华州的形态动力学响应。结果将被用来测试的假设，片流过程占主导地位的山脊和隧道迁移，并制定一个全面的了解，这些系统的形态演变，从一开始就通过附件的海滩。这项研究可能会导致更好的管理海滩侵蚀和恢复。该项目将支持一名博士生（招聘对象为代表性不足的少数群体）和两名本科生。PI将建造和培训教师操作一个便携式水槽，供三所德克萨斯州高中参加？教室里的海滩？程序.项目成果将纳入得克萨斯州和特拉华州的公共外联活动。

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.
