(CAREER) Career Development in Geological and Environmental Fluid Mechanics

9701768 Manga本提案描述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，用归纳法取代标准的片断和现象学教学；课程将侧重于一套强调发现过程的动手主动学习实验室实验。还将开发一套研究生课程，侧重于跨学科合作研究项目，重点是互动学习和交流。一系列相辅相成的研究活动将解决水文学、地球动力学和火山学方面的问题。这项工作将涉及课堂上使用的相同的理论和实验相结合的方法。具体的研究问题包括：研究俄勒冈瀑布以泉水为主的溪流的水文学(研究将并入夏季野外学校)；描述泡状岩浆和熔岩的动力学和流变性；建立多孔材料中多相流的孔长模型，以了解这种流动的宏观性质；将地球地幔的化学演化与动态过程联系起来。尽管这些研究问题范围很广，但它们都有一个共同的特点，那就是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。预计实验练习和研究生课程的大部分材料将由这些研究问题提供，实验练习的发展将最终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.
