Indicate the student audience for which this course is designed
and the anticLpated enrollment.
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.

Educational POllCY Advisory Committee's attention.
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 .

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.

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.

Continued
This type of material can only be touched on to a limited extent in a Physical Geology
(GEO.117) course which has much broader goals. Geology 101 -is a bonafide attempt to
give students a firm foundati-on in the basic geological aspects of the environment
we live in.

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:
