Conference Support: 'Coherent Flow Structures in Geophysical Flows at the Earths Surface'

该项目将提供会议支持，以协助美国- 2010年，来自美国的年轻研究人员（研究生、博士后研究员、终身教职人员）参加了一个关于“地球表面地球物理流动中的相干流结构”的国际会议。 会议的目的是汇集研究团队谁是使用数值模拟，实验室建模和实地观察，以研究相干流结构，其与沉积物，植被和底栖生物群落的相互作用，这种流动结构的管理沉积环境的操纵，以及它们在地球表面动力学中所起的关键作用。地球表面在很大程度上是由运动的流体和床面地形之间的相互作用所塑造的（在空气、水和固体的流动中）。几十年来，许多工作都试图将湍流结构的细节与沉积物的输运、河床地形的发展以及这三者之间的反馈联系起来。调查这其中的联系？逢三杀手在过去的20年里，流动，形式和运输的基础上进行了大量的研究，并揭示了关键作用？相干流结构控制和调节这Trinity。流动结构，移动的沉积物和表面形态之间的相互作用，从而成为了解地球动力学的核心重要性？s表面。此外，管理此类水流是可持续工程设计/施工（如桥墩、翼堤和护岸周围的水流）以及维护生态栖息地的关键组成部分。 这个跨学科的研究领域正在培养新的年轻研究人员，他们将数值，实验室和现场研究无缝集成，以推进监测和建模。因此，该项目的一个明显的影响是支持在这一领域的早期职业跨学科研究人员的发展。

This project will provide conference support to assist U.S.-based young researchers (graduate students, postdoctoral fellows, pre-tenure faculty) attend an international conference on 'Coherent Flow Structures in Geophysical Flows at the Earth's Surface'. The objective of the conference is to bring together research teams who are using numerical simulation, laboratory modeling, and field observation to study coherent flow structures, their interaction with sediment, vegetation, and benthic communities, the manipulation of such flow structures for managing sedimentary environments, and the key role they play in Earth surface dynamics.Earth's surface is largely sculpted by the interactions between moving fluids and the bed topography (in flows of air, water, and solids). Much work over many decades has sought to link the detail of the turbulent flow structure to the transport of sediment, to the development of bed topography, and to the feedbacks between these three. Investigation of the linkages in this ?trinity? of flow, form and transport have underlain much research over the past 20 years and have revealed the pivotal role of ?coherent flow structures? in controlling and modulating this trinity. The interaction between flow structure, mobile sediment, and surface morphology has thus become of central importance to understanding the dynamics of the Earth?s surface. Additionally, managing such flows is a key component of both sustainable engineering design/construction (such as flows around bridge piers, wing dykes and revetments) as well as in the maintenance of ecological habitats. This interdisciplinary field of study is developing new young researchers who are seamlessly integrating numerical, laboratory, and field research to advance monitoring and modeling. A clear impact of this project is thus to support the development of early career interdisciplinary researchers in this area.
