Collecting data needed to decipher how groundwater occurs, moves, and transmits contaminants most often requires boring into the groundwater system, installing wells, and measuring water levels. This book provides instructors with an easy-to-install classroom-scale physical, three-dimensional interactive monitoring well network that is used to introduce and reinforce basic hydrogeological concepts. The PVC tube-based physical model allows students to participate in groundwater data collection and interpretation. Students working in groups interactively measure water levels in model wells, compute hydraulic heads at each well, plot and contour head data creating equipotential maps, and interpret and visualize two-dimensional and three-dimensional groundwater flow directions. An example of a model setup with analyses is provided. A parts list and unit costs of materials are also included. The model configuration can easily be modified by the instructor. This inexpensive physical model works well in a classroom or in an outdoor space as a standard component of a university groundwater curriculum, hydrogeology laboratory or field camp, high school groundwater learning module, and is well-suited for use in continuing education and community outreach settings promoting groundwater education.
