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

该项目将提供会议支持，帮助在美国的年轻研究人员（研究生、博士后、终身教职前教员）参加“地球表面地球物理流动中的相干流结构”国际会议。会议的目的是将使用数值模拟、实验室建模和实地观测的研究团队聚集在一起，研究连贯的流动结构，它们与沉积物、植被和底栖生物群落的相互作用，控制这种流动结构以管理沉积环境，以及它们在地球表面动力学中发挥的关键作用。地球表面很大程度上是由流动的流体和河床地形（空气、水和固体的流动）之间的相互作用形成的。几十年来，许多工作都试图将湍流结构的细节与沉积物的搬运、河床地形的发展以及这三者之间的反馈联系起来。调查三位一体案的关联？在过去的20年里，关于流动、形态和运输的许多研究都揭示了水流的关键作用。连贯的流结构？在控制和调节这三位一体。因此，水流结构、流动沉积物和地表形态之间的相互作用已成为理解地球动力学的核心重要性。年代的表面。此外，管理这类水流是可持续工程设计/施工（如桥墩、护岸和护岸周围的水流）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，他们将数字，实验室和现场研究无缝地整合在一起，以推进监测和建模。因此，该项目的一个明显影响是支持该领域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.
