项目摘要

ABSTRACTPROPOSAL NO.: CTS-047014, 0426811, 0427115PRINCIPAL INVESTIGATORS: P. LYNETT, B. RAUBENHEIMER, P. LIUINSTITUTION: TEXAS A&M UNIVERSITY, WOODS HOLE OCEAN INST., CORNELL UNIVERSITY COLLABORATIVE: ITR COASTAL MODELING AND MANAGEMENTThe goal of this grant to develop a coupled, hybrid hydrodynamic computational model for simulation and prediction of complex water wave processes from the deep ocean to the shoreline. The model will be physically comprehensive, with total domain scales on the order of hundred's of kilometers, yet with a nearshore grid resolution less than a meter. To include this great range of scales, a number of diverse hydrodynamic models, with various but overlapping physical and practical constraints, will be integrated to create a hybrid hydrodynamic software tool. The method of interfacing the different hydrodynamic models will be founded in distributed computing techniques, thereby allowing for utilization of computer cluster resources. In addition, each of the individual models in the hybrid system will be parallelized, leading to the creation of a massively parallel and distributed simulation platform. Coupled with the hybrid hydrodynamic model will be sediment transport formulations, such that morphological change in the nearshore (i.e. beach erosion) can be simulated. These formulations will employ the fine resolution and high fidelity wave forcing from the hydrodynamic model, including the effects of strong turbulence in the breaker, surf, and swash zones. Validation of the coupled model will use established datasets from field studies and controlled experiments. The technology infrastructure developed to pass information between the various coupled models will be transparent and expandable, such that as more sophisticated models become available, they may be plugged into the existing simulator. The coupled simulator will be utilized by practicing engineers for design of coastal protection measures and by policy makers who may need better estimations of wave impact and erosion due to extreme events. By influencing future design and policy decisions, the simulator will contribute towards the goal of sustainable coastal margins. Education and outreach will be accomplished through the unveiling of a web-based, open access, coastal simulator. The website will be completely free access, open to college and high school students, as well as academics and engineers. The coastal simulator will be used remotely for senior level coastal engineering design classes. It would be of immense impact to be able to show these students first-hand the level of uncertainty and possible error in common engineering tools through comparison with the high accuracy model developed here, such that they are in a much better position to interpret the predictions when they become practicing engineers. Jointly funded by the Division of Chemical & Transport Systems, Fluid Dynamics & Hydraulics (FDH) program, and the Division of Ocean Sciences (OCE).
ABSTRACTPROPOSAL没有。主要研究人员:P. LYNETT, B. RAUBENHEIMER, P. liu研究机构:TEXAS a&m UNIVERSITY, WOODS HOLE OCEAN institute, CORNELL UNIVERSITY合作:ITR海岸建模与管理本基金的目标是开发一个耦合的混合水动力学计算模型,用于模拟和预测从深海到海岸线的复杂水波过程。该模型将具有物理上的综合性,总域尺度为数百公里,但近岸网格分辨率不到一米。为了包含这个大范围的尺度,将整合许多不同的流体动力学模型,这些模型具有不同但重叠的物理和实际限制,以创建混合流体动力学软件工具。将不同的水动力模型连接起来的方法将建立在分布式计算技术中,从而允许利用计算机集群资源。此外,混合系统中的每个单独模型都将被并行化,从而创建一个大规模并行和分布式仿真平台。与混合水动力模型相结合的是泥沙输运公式,这样可以模拟近岸的形态变化(即海滩侵蚀)。这些公式将采用来自水动力模型的精细分辨率和高保真波强迫,包括破碎区、冲浪区和冲浪区强烈湍流的影响。耦合模型的验证将使用来自实地研究和对照实验的既定数据集。为在各种耦合模型之间传递信息而开发的技术基础结构将是透明的和可扩展的,这样当更复杂的模型可用时,它们就可以插入到现有的模拟器中。该耦合模拟器将被实践工程师用于设计海岸防护措施,并被决策者使用,他们可能需要更好地估计极端事件造成的波浪冲击和侵蚀。通过影响未来的设计和政策决策,模拟器将有助于实现可持续沿海边际的目标。教育和推广将通过推出一个基于网络的、开放获取的沿海模拟器来完成。该网站将完全免费访问,向大学和高中生以及学者和工程师开放。沿海模拟器将远程用于高级海岸工程设计课程。通过与这里开发的高精度模型进行比较,能够向这些学生展示普通工程工具中不确定性和可能错误的第一手水平,这将产生巨大的影响,这样当他们成为实践工程师时,他们就能更好地解释预测。由化学与运输系统部、流体动力学与水力学部(FDH)和海洋科学部(OCE)共同资助。
