Graduate Research Traineeships in Hydrology: Role of the Hydrologic Cycle in the Coupled Earth System

水循环是所有地球系统循环中最基本的循环，将固体地球、海洋和大气联系在一起。水通过这些地球系统组成部分的无尽循环产生了在整个时空尺度上的相互作用。直到最近，人们才认识到，这些相互作用的双向性质对气候、天气、生物地球化学循环和生态系统动力学有着深远的影响。在地球系统的所有部分，水文过程同时影响并受物理、化学和生物过程的影响，这一观点为德克萨斯大学奥斯汀分校水文科学多学科GRT项目提供了框架。通过这一教育和研究主题，我们希望向学生传授传统水文学专业目前缺乏的科学基础，同时培养一批在水文学领域长期领导的科学人才。鉴于地质科学系最近增加了新的水文学教员，包括最先进的分析和计算机模拟设施，再加上该系下属的经济地质局、地球物理研究所和空间研究中心以及土木工程系现有的水文学实力，现在已经具备了一个临界质量，因此真正独特的、跨学科的研究和教育活动可以在统一的主题下启动一个GRT计划在水文-地球系统相互作用。我们的GRT项目包括许多结构上的创新，包括与联邦研究机构的合作安排、渐进式的新课程设置、为研究员举办的教学效率研讨会、为研究员提供在课堂上应用先进技术的教学机会，以及为研究员提供在当地“合作”机构指导本科生的机会。招聘计划包括与当地合作机构的合作安排，一个由系里赞助的研讨会论坛和捐赠的讲师，以及一个向有大量西班牙裔或非裔美国人入学的德州地区大学拓展的计划。

The hydrological cycle is the most fundamental of all earth system cycles, linking together the solid earth, the oceans, and the atmosphere. The endless cycling of water through these earth system components yields interactions over the full spectrum of spatial-temporal scales. Only recently has the picture emerged that the two-way nature of these interactions has profound impacts on climate, weather, biogeochemical cycles and ecosystem dynamics. The view that hydrological processes simultaneously affect and are affected by physical, chemical, and biological processes, in all compartments of the earth system, provides the framework for a multi-disciplinary GRT program in hydrological sciences at UT Austin. With this educational and research theme, we hope to impart to our students the scientific underpinnings which are currently absent from traditional hydrology programs, while cultivating a pool of scientific talent to provide long-term leadership in the field of hydrology. Given the recent addition of new hydrology faculty in the Department of Geological Sciences, including state-of-the-art analytical and computer modeling facilities, combined with existing hydrological strength in the department-affiliated Bureau of Economic Geology, the Institute for Geophysics, and the Center for Space Research, as well as in the Department of Civil Engineering, a critical mass now exists so that truly unique, interdisciplinary research and education initiatives can be launched under the unifying theme of a GRT program in hydrology-earth system interactions. Our GRT program includes a number of structural innovations, including collaborative arrangements with federal research organizations, progressive new course offerings, teaching effectiveness seminars for fellows, teaching opportunities for fellows involving advanced technology applications in the classroom, and opportunities for fellows to mentor undergraduates in a local "partnership" institution. Recruitment pl ans include a consortial arrangement with the local partnership institution, a department-sponsored seminar forum and endowed lectureships, and an outreach program to regional Texas colleges with large Hispanic or African-American enrollments.
