This course is designed primarily for non-science majors in all Colleges with natural science requirements. The enrollment in the course will probably be 40=100 per section. This figure is based on enrollment in our other 100 level 3 credit hour courses Geography 100 and Geography 102. 4. How often will this course be offered? This course will probably be offered once a semester and at least once per summer. The number and frequency of offerings is tied to thenecessity of covering all the required courses within the geology program. Anyone of the geology faculty is capable of offering the program in any given semester. ... \1 Course Justification Form 5.

The title of the course Environmental Geology might give the impression that the course is in potential conflict with biology courses. However, a look at the syllabus and course outline clearly shows that this is a geology course emphasizing geological phenomena and man's interaction and manipulation of the environment with no concern for the geology of an area. The emphasis of the course is on the physical environment: soils, bedrock, structures, aquifers etc . . , " 6. If t~is course is an addition to the present curriculum provide a detalle~,narr~tive justification of the need for this c~urse II This course is needed to help make more students aware of the many ways that the geology of any area affects the environment and can lead to potentially hazardous living I conditions. During just this past semester when this material was studied by honors . students several major disasters in Mexico City, Colombia and Puerto Rico occurred which I brought some of the problems associated with volcanoes, earthquakes, and landslides in ~ focus. Other major problems associated with ground collapse nnd subsidence, floods and I water supply, waste disposal etc. will also be covered as aprt of the course. The need for this course is consistent with the present and future direction of the Department's academic and research interests. Greater emphasis is being placed on toxic wastes, water resources, and pollution as well as expanded development into more hazardous physical environments. 7. We in the depa r~ment see more of our411aj or$ ·'g01 ng into these fi e 1ds & work-tng oDgeotechnrtd:ajl geohydrologica1 and environmental problems. However, there is a very strong need and I even an obligation on our part to provide the material in this course to UNO students at large. They are the ones who will be going out there and making decisions about how to conserve our natural resources, where a landfill should or should not be sited and whether or not a toxic waste dump should be located in their community. It is our responsibilty to provide them with a basic understanding of the concepts and facts available in these areas so that they make inforllled decisions. The students :shoulij be given enough background information so that they will know where to look for other resources to assist them in their decision. (see continuation on separate sheet) If a new graduate course, the dean having budgetary responsibility for the department should sign here to indicate that resources currently are available to add the course to the curriculum.

Land use compatible with the geology of urban areas Examples of recent land management strategies Method of Instruction and Evaluation This will be a standard lecture-type course format with a few additional presentations by outside speakers from the Corps of Engineers and local geotechnical companies. In addition several film/videotape series will be shown to illustrate the Mt. St. Helens eruption, the earthquake potential of the San Andreas fault in the San Francisco areS5 landslide potential in Scandinavia, the use and misuse of the Colorado River water and the cleaning up of the Willamette River system. These films will be used to focus the material presented in the text and lectures. The emphasis will be on recognizing and solving problems associated with the physical environment. Students will be encouraged to read media reports on national and international events (major earthquakes, floods, volcanic eruptions, etc.) and to ask questions about these during the class. There will be three one-hour examinations and a final using a con~inBtion of formats (short answer, definition5 fill-in-the-blank, recognition of map/diagram features and multiple choice. An extra credit project may be offered to the students which will consist of a collection of pertinent articles and a short analysis of the environmental impact of the event or problem outlined in the articlen The textbook to be used in the class will be: SURFICIAL GEOLOGY: Building With the Earth by John E.
