Environmental fluid mechanics underlies a wealth of natural, industrial, and, by extension, societal challenges. In the coming decades, as we strive towards a more sustainable planet, there are a wide range of Grand Challenge problems that need to be tackled, ranging from fundamental advances in understanding and modeling of stratified turbulence and consequent mixing, to applied studies of pollution transport in the ocean, atmosphere, and urban environments. A workshop was organized in the Les Houches School of Physics in France in January 2019 with the objective of gathering leading figures in the field to produce a road map for the scientific community. Five subject areas were addressed: multiphase flow, stratified flow, ocean transport, atmospheric and urban transport, and weather and climate prediction. This article summarizes the discussions and outcomes of the meeting, with the intent of providing a resource for the community going forward.

面对环境流体力学的重大挑战

环境流体力学是自然，工业以及社会挑战的基础。在未来的几十年中，随着我们朝着更加可持续发展的星球努力，需要解决一系列大挑战，从理解和模拟分层湍流及其结果混合的根本进展，到污染运输的应用研究，一应俱全。在海洋，大气层和城市环境中。2019年1月在法国Les Houches物理学院举办了一个讲习班，目的是收集该领域的领先人物以为科学界制定路线图。涉及五个主题领域：多相流，分层流，海洋运输，大气和城市运输以及天气和气候预测。
