The use of Geographical Information Systems (GIS) was implemented in the upper-division undergraduate technical elective Introduction to Environmental Engineering at Harvey Mudd College. Students integrated technical engineering skills, newly-learned geographical information system (GIS) skills, and the engineering design process, all in the context of the design of a debris flow barrier for a wilderness land parcel acquired by a local conservancy group. Junior and senior general engineering students, the majority of whom had no experience with GIS, were taught ArcGIS (a GIS mapping program) in the context of an Introductory Environmental Engineering course. Students learned how to map locations, find and download geo-encoded data, and join data layers, in order to graphically present toxic release hazards near their home towns. ArcGIS skills and knowledge were assessed through completion of homework problems, and through the students' use of GIS data, software, and mapping during the design of a debris flow barrier for a local wilderness land parcel.
