(CAREER) Career Development in Geological and Environmental Fluid Mechanics

小行星9701768 该提案介绍了地质和环境流体力学领域的长期教育和相关研究活动。 将开发一套本科课程，以取代标准的零碎和现象学教学的主题与归纳法;类将集中在一套动手主动学习实验室实验，强调发现的过程。 还将开发一套研究生课程，重点是跨学科的合作研究项目，重点是互动学习和交流。 一系列补充研究活动将处理水文学、地球动力学和火山学方面的问题。 这项工作将涉及将在课堂上使用的理论和实验方法的相同组合。 具体的研究问题包括：研究俄勒冈州瀑布以春季为主的溪流的水文学（研究将纳入夏季野外学校），描述泡沫状岩浆和熔岩的动力学和流变学，开发多孔材料中多相流的孔隙长度尺度模型，以了解这种流动的宏观特性，以及将地幔的化学演化与动力学过程联系起来。 尽管这些研究问题的范围很广，但它们都有一个共同的特点，即将流体力学中的定量方法应用于地质和环境科学中的问题。 预计这些研究问题将为实验练习和研究生课程提供大量材料，实验练习的发展将为新的研究方向提供灵感。

9701768 Manga This proposal describes long-term educational and related research activities in the area of geological and environmental fluid mechanics. A set of undergraduate courses will be developed to replace the standard piece-meal and phenomenological teaching of the subject with an inductive approach; classes will focus on a set of hands-on active-learning laboratory experiments which emphasize the process of discovery. A set of graduate classes will also be developed which focus on interdisciplinary collaborative research projects, with an emphasis on interactive learning and communication. A set of complementary research activities will address problems in hydrology, geodynamics and volcanology. This work will involve the same combination of theoretical and experimental approaches that will be used in the classroom. Specific research problems include studying the hydrology of spring-dominated streams in the Oregon Cascades (research will be integrated into a summer field school), characterizing the dynamics and rheolgy of bubby magmas and lavas, developing pore length-scale models of multiphase flow in porous materials in order to understand macroscopic properties of such flows, and relating the chemical evolution of the Earth's mantle to dynamic processes. Despite the wide range of these research problems, they all share a common feature, namely, the application of quantitative methods in fluid mechanics to problems in the geological and environmental sciences. It is anticipated that much of the material for lab exercises and graduate classes will be provided by these research problems, and that the development of lab exercises will in tern provide inspiration for new research directions.
