COURSE OBJECTIVES

The course is intended to be a practical, hands-on, field-oriented course on the applications of geophysics to hydrogeologic problems. The underlying focus of the course will be to use geophysics to help answer one or both of the following questions: Where is the water in the system? How will water flow in the system?

For each topic, the development will proceed from basic principles (theory) through methodology and applications, to case histories. Applications will be emphasized, theory will be kept to essentials. The basic principles and operational procedures of each method will be presented, along with discussions of where the method is and is not applicable. Case histories will be included to illustrate applications. Assigned readings and literature reviews will be an integral part of the course work. Reading lists and abstracts of numerous articles on each topic will be made available.

FIELD DAYS

Three or four weekend days: Oct 4, 11, 18, and 25; 8 AM - 6 PM, transportation and equipment provided. Bring your own food and drink, and be prepared for hot and cold weather.

COURSE LOGISTICS

  1. Textbook: As hydrogeophysics is a rapidly evolving discipline, there is no textbook required for the class. Consult the list of books on reserve for the class in the DeLaMare Library for information on books that the lectures and labs were drawn from, and recommended purchases.

  2. Lecture Notes: We will attempt to hand out at least an outline of the topics to be covered at the beginning of each lecture. Copies of the overheads will be made available for copying as soon as possible after each lecture.

  3. SAGEEP '97 Reading: Each 50-minute lecture period will begin with a 10-minute presentation by one student, in turn among the class; on one of the papers selected from the SAGEEP '97 Proceedings whose page numbers appear above for each lecture. (The SAGEEP Proceedings volumes are not owned by the UNR Libraries.) The presenter will prepare 1 to 3 overhead transparencies from the paper, and concentrate on explaining the hydrogeologic motivation and practical success of the work.

  4. Labs: Many of the lab/field exercises will require use of one of the MSM computer labs. Labs will not meet formally every week. Formal sessions will be scheduled as above to introduce the software for each lab, and then students will be left on their own to complete lab assignments. We intend that the instructors will be available at least part of the scheduled lab times to assist students. Students are encouraged to work together on lab assignments, but should turn in their own work. Lab write-ups are due one week after the scheduled lab section.

  5. Field Reports: Each student will prepare a final report integrating and interpreting all of the geophysical data gathered by the class field exercises. While the class will collectively analyze the data obtained, students will be responsible for their own written reports. Each should describe the objectives, previous work, methods, results, and implications of the entire project in about 10 pages of text, plus figures. Reports attaining high grades will have to be of professional quality. During the class's final exam period, each group overseeing the individual field methods will collaborate on a half-hour presentation of results and implications from that method.

  6. Grading: In general, work turned in late will be penalized 10%, or one whole grade. The final course grade will be 30% from lab exercise scores, 30% from test scores, 30% from the final report score, and 10% an assessment of paper and final presentations.
