9978335BeckerEvery geoscience instructor recognizes the value of learning-by-doing, and the motivational advantage of real-world data. Real hydrologic data is available on the Internet and other sources, but rarely are the data sets comprehensive or placed in the context of a larger Earth system. This Interactive Teaching Database (ITD) will offer over 40 years hydrologic information collected at the Hubbard Brook Experimental Forest, in a form that will allow for effective implementation in the classroom. Detailed hydrologic data concerning the atmospheric, surface, and ground water fluxes to Mirror Lake will be provided, along with more general information about the hydrology, geology, and ecology of the Hubbard Brook Valley. Thus, the instructor of hydrology will be able to create instructional exercises involving these data in the context of a larger environmental system. In addition, the hydrologic ITD will include an interactive companion study guide that provides students the opportunity to practice advanced hydrologic quantitative methods. This guide will take advantage of the latest in internet-based scientific visualization technology, including Java applets and VRML based three-dimensional interactive objects. The skills to be practiced include estimating baseflow and ground-water recharge using streamflow recession, estimating evapotranspiration using an energy balance, calculating the hydrologic budget of a watershed, and developing a numerical model of ground-water flow. Calculations will be carried-out using spreadsheets, simple Java-based algorithms, and the ground-water model MODFLOW. Educational problems and the underlying data will be based on published studies by the U.S. Geological Survey to ensure data quality and to provide a resource for upper-level undergraduate and entry-level graduate instruction, the ITD will also be the first comprehensive digital compilation of data resulting from the intensive hydrologic study of the Mirror Lake surface and ground water basin. The ITD will be designed with an open architecture, so that in the future it may be expanded to include more of the tremendous amount of ecologic, hydrologic, and geologic data that have been collected at Hubbard Brook Experimental Forest.

9978335每位地球科学教师都认识到边做边学的价值，以及真实世界数据的激励优势。真实的水文数据可以在互联网和其他来源上获得，但很少是全面的数据集，或者放在更大的地球系统的背景下。这个交互式教学数据库(ITD)将提供在哈伯德·布鲁克实验森林收集的超过40年的水文信息，其形式将允许在课堂上有效实施。将提供有关进入镜湖的大气、地表水和地下水通量的详细水文数据，以及关于哈伯德·布鲁克山谷的水文、地质和生态的更多一般信息。因此，水文学讲师将能够在更大的环境系统的背景下创建涉及这些数据的教学练习。此外，水文学ITD将包括一个互动的同伴学习指南，为学生提供实践先进的水文定量方法的机会。本指南将利用最新的基于互联网的科学可视化技术，包括Java小程序和基于VRML的三维交互对象。需要练习的技能包括使用径流倒退估计基流和地下水补给、使用能量平衡估计蒸散量、计算流域的水文收支，以及开发地下水流动的数值模型。计算将使用电子表格、简单的基于Java的算法和地下水模型MODFLOW进行。教育问题和基础数据将基于美国地质调查局发表的研究，以确保数据质量，并为高水平的本科生和初级研究生教学提供资源，ITD也将是第一个对镜湖地表和地下水盆地进行密集的水文研究所产生的数据的全面数字汇编。ITD将采用开放式架构设计，因此未来可能会扩展到包括哈伯德·布鲁克实验森林收集的大量生态、水文和地质数据。
