IGW/DL: A Digital Library for Teaching and Learning Hydrogeology and Groundwater Modeling

Introduction Since the advent of the Internet era and the World Wide Web, teaching and learning has no doubt become easier and resources more accessible. Currently, there is a wealth of useful information freely available online for teaching and learning hydrogeology and groundwater modeling. However, few are as well designed and visually compelling as an educational digital library (DL) called “Interactive Ground Water (IGW) Visualization Library” at the website http://www.egr.msu.edu/igw/DL/. IGW/DL was originally developed for the National Science Foundation’s Digital Library Initiative and is continually improved and maintained by Professor Shuguang Li and his associates at Michigan State University. In this column, we review the contents included in the IGW/DL and report our experience in using this innovative online resource.
