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沟渠系统有关的水动力学和泥沙输送过程。从波浪水槽实验中开发的新的现场技术将与遥感方法相结合，以量化特拉华州雷霍博斯海滩山脊和沟渠系统中的片流、悬浮泥沙输送和地貌动力学响应。结果将被用来检验席流过程主导山脊和沟道迁移的假设，并发展对这些系统从开始到附着到海滩的形态演变的全面理解。这项研究可能有助于改进对海滩侵蚀和恢复的管理。该项目将支持一名博士生(招聘对象为少数族裔)和两名本科生。PI将建造和培训教师操作便携式水槽，供参加海滩的三所德克萨斯州高中的教室使用。程序。项目成果将纳入德克萨斯州和特拉华州的公共宣传活动。

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.
