Undergraduate environmental education for students majoring in hydrology and other environmental science and engineering disciplines should be centered around practical applications. Students must understand the critical scientific and engineering issues and become proficient in solving multidisciplinary problems using high-technology tools. This project improves existing field and laboratory facilities by providing such tools to undergraduate students from several departments in three colleges at the university. Undergraduate environmental courses have been taught with laboratory components, in which practical aspects of environmental science and engineering are emphasized. This project provides for the field and laboratory equipment needed to improve the current disciplinary laboratory courses and to initiate new multidisciplinary courses that aim to develop in students the ability to integrate knowledge across traditional disciplines. The facility consists of three integrated parts: (1) a field site equipped with pumping/injecting wells, monitoring wells, and accessories; (2) a physical and chemical laboratory equipped for determination of soil and water properties; and (3) a computer laboratory equipped for data acquisition, analysis, interpretation, and visualization. Field experiments deal with water flow, water resources evaluation, water chemistry and quality, and geophysical methods. In the laboratory, tests are performed to determine physical and chemical properties of soils and chemical composition of water. The results of field and laboratory experiments are analyzed using data reduction and data visualization software. The following courses use the laboratory: hydrogeology, subsurface hydrology, water chemistry, vadose zone monitoring methods, vadose zone hydrology, groundwater resources evaluation, well logging, and environmental monitoring. *

水文学等环境科学与工程专业本科环境教育应以实际应用为中心。学生必须了解关键的科学和工程问题，并熟练使用高科技工具解决多学科问题。该项目通过向大学三个学院的几个系的本科生提供这些工具，改善了现有的野外和实验室设施。本科环境课程以实验室教学为主，强调环境科学和工程的实践方面。该项目提供了所需的现场和实验室设备，以改进当前的学科实验课程，并启动新的多学科课程，旨在培养学生整合传统学科知识的能力。该设施由三部分组成：(1)配备泵/注水井、监测井和附件的现场；（二）具有测定土壤、水性质的理化实验室；(3)配备数据采集、分析、解释和可视化的计算机实验室。现场实验涉及水流、水资源评价、水化学和水质以及地球物理方法。在实验室中，进行测试以确定土壤的物理和化学性质以及水的化学成分。利用数据约简和数据可视化软件对现场和室内试验结果进行了分析。以下课程使用实验室：水文地质学、地下水文学、水化学、渗透带监测方法、渗透带水文学、地下水资源评价、测井和环境监测。＊
