CAREER: Swashzone Processes

摘要/机构：Raubenheimer / WHOI提案编号：OCE-总体的、长期的科学和教育目标是开发和验证冲积带（海滩面被风浪交替覆盖和暴露的区域）的流体和沉积物过程模型，提高公众解释科学结果的能力，并提高对影响海滩和近岸的过程的认识。拟议工作的具体目标是调查激流区过程，制定一个向任何大学学生开放的近岸过程本科实习计划，并参与开发基于互联网和实地观测海洋学课程。拟议的工作将评估有关流动对海滩斜坡和近海波浪条件的依赖，冲积中的床应力，亚重力能对沿岸冲积带流动的重要性，海岸侵蚀速率的变化以及冲积带沉积物运输的重要过程的假设。拟议的为期6个月的研究实习将补充和扩展伍兹霍尔海洋研究所现有的为期2个月的暑期学生奖学金计划，并将使学生有时间熟悉背景文献和计算机分析和编程技术，制定详细的研究计划，进行实验和收集观察数据，必要时分析数据。拟议的课程开发预计将为小型学院的本科生提供学习影响海滩的过程（例如，侵蚀，离岸流和冲浪）以及收集近岸观测所需的现场技术的机会。课程模块的开发将与为本科生创建一套远程学习机会的原型相辅相成，并将包含(1)流体力学和沉积物运输的材料，(2)仪器和采样策略的信息，(3)参与小型现场实验，可能与拟议的本科生研究项目结合起来。预计内容的模块化性质将使网络信息能够在各种课程中使用。总体的、长期的科学和教育目标是开发和验证冲积带（海滩面被风浪交替覆盖和暴露的区域）的流体和沉积物过程模型，提高公众解释科学结果的能力，并提高对影响海滩和近岸的过程的认识。拟议工作的具体目标是调查激流区过程，制定一个向任何大学学生开放的近岸过程本科实习计划，并参与开发基于互联网和实地观测海洋学课程。拟议的工作将评估有关流动对海滩斜坡和近海波浪条件的依赖，冲积中的床应力，亚重力能对沿岸冲积带流动的重要性，海岸侵蚀速率的变化以及冲积带沉积物运输的重要过程的假设。拟议的为期6个月的研究实习将补充和扩展伍兹霍尔海洋研究所现有的为期2个月的暑期学生奖学金计划，并将使学生有时间熟悉背景文献和计算机分析和编程技术，制定详细的研究计划，进行实验和收集观察数据，必要时分析数据。拟议的课程开发预计将为小型学院的本科生提供学习影响海滩的过程（例如，侵蚀，离岸流和冲浪）以及收集近岸观测所需的现场技术的机会。课程模块的开发将与为本科生创建一套远程学习机会的原型相辅相成，并将包含(1)流体力学和沉积物运输的材料，(2)仪器和采样策略的信息，(3)参与小型现场实验，可能与拟议的本科生研究项目结合起来。预计内容的模块化性质将使网络信息能够在各种课程中使用。

ABSTRACTPI/Institution: Raubenheimer / WHOI Proposal No: OCE- ABSTRACTPI/Institution: Raubenheimer / WHOI Proposal No: OCE-0239033 The overall, long-term scientific and educational objectives are to develop and validate models for the fluid and sediment processes in the swash zone (the region where the beach face is alternately covered and uncovered by run-up from wind waves), to improve the publics ability to interpret scientific results, and to increase awareness of the processes that affect the beaches and nearshore. The specific goals of the proposed work are to investigate swashzone processes, to develop an undergraduate internship program in nearshore processes open to students at any university, and to participate in the development of an internet- and field-based observational oceanography class. The proposed work will evaluate hypotheses concerning the dependence of flows on beach slope and offshore wave conditions, bed stresses in the swash, the importance of infragravity energy to alongshore swashzone flows, the longshore changes in erosion rates, and the processes important to swashzone sediment transport.The proposed 6-month research internships will supplement and extend the existing 2-month Summer Student Fellowship program at Woods Hole Oceanographic Institution and will allow time for students to become familiar with background literature and computer analysis and programming techniques, to develop a detailed research plan, to conduct experiments and collect observations if necessary, and to analyze the data. The proposed course development is expected to provide undergraduates at small colleges the opportunity to learn about the processes that affect the beaches (e.g., erosion, rip currents, and surf) and the field techniques needed to collect nearshore observations. The development of course modules will be synergistic with the creation of a prototype set of distance-learning opportunities for undergraduates and will contain (1) material on fluid mechanics and sediment transport, (2) information on instrumentation and sampling strategies, (3) participation in a small field experiment, possibly in conjunction with the proposed undergraduate research projects. It is expected that the modular nature of the content will enable the web information to be used in a variety of courses.
