A wide variety of methods including seismic reflection, seismic refraction, electromagnetic, ground-penetrating radar, potential fields, electrical resistivity, and borehold logging will be introduced and examined. Natural and manmade disasters will be discussed. *Prerequisite(s): PHY 201 and MA 122. Spring semester, even-numbered years. Course Objectives Acquire an appreciation and understanding of the chemical composition and physical properties of Earth materials that will support an understanding of the geophysical response required to facilitate subsurface imaging methods. Develop an understanding of the different types of engineering and environmental targets and the most effective geophysical methods that can be utilized to characterize those targets. Develop an understanding of each of the near-surface geophysical imaging methods: seismic, electromagnetic, ground-penetrating radar, gravity, magnetic, electrical resistivity, induced polarization, geothermal, and geophysical borehole logging. Acquire experience with the application of geophysical methods through examination of case studies and participation in field operations that utilize these imaging techniques. Develop an understanding of the different types of engineering and environmental targets and the most effective geophysical methods that can be utilized to characterize those targets. Achievement & Assessment of Course Objectives & Learning Outcomes Reading assignments as outlined below, followed by lecture and discussion meetings will serve to introduce and develop an understanding of the topics being presented. Weekly participation activities supplemented by discovery-oriented activities will deliver insights that re-enforce and deepen understanding. Assessment of performance will be accomplished through feedback provided by instructors on weekly participation activities, lab/discoveryoriented activities, and exams.

Policy Items This course will operate according to the Elizabethtown College Pledge of Integrity. Any suspected cases of academic dishonesty will be handled according to the guidelines under “Academic Judicial System,” in the Elizabethtown College Catalog. If you have a documented disability and need reasonable accommodations to fully participate in course activities or meet course requirements, you must: (1) Contact the Director of Learning Services and Disability Services, Dr. Kristen Sagun, in the Center of Student Success, BSC 226, (717) 361-1549, AND(2) Meet with me, the instructor, within two weeks of receiving a copy of the accommodation letter from Disability Services to discuss your accommodation needs and their implementation. The participation grade (see below) will be based on text assignments, in-class assignments, quizzes, discovery-oriented activities provided by the instructor. By its very nature, no participation assignment can be accepted late. [If you’re not participating, for any reason, you can’t receive credit for participation.] Course grades will be based on a system of point accumulation as indicated below. Part I (Exam I =100pts; Participation = 100pts.) 200 points Part II (Exam I =100pts; Participation = 100pts.) 200 points Part III (Exam II =100pts; Participation = 100pts.) 200 points _________ Total: 600 points Points Grade in Course 570 – 600 A 540 – 569 A- 516 – 539 B+ 498 – 515 B 480 – 497 B- 456 – 479 C+ 438 – 455 C 420 – 437 C- 396 – 419 D+ 378 – 395 D 360 – 377 D- Below 360 F Grades will be determined as outlined above. No other considerations are available. Make-up exams available only with instructor approval (emergency only); convenience is not an emergency. Make-up exams will differ from the scheduled exam. Course Outline Introduction Engineering/Environmental geophysics involves the application of subsurface imaging techniques to locate boundaries or discontinuities in subsurface rock materials across which there is a marked contrast in physical properties. Such contrasts can be detected remotely from the surface because they give rise to geophysical anomalies which permit subsurface variations in physical properties to be identified and mapped. Most targets of engineering and environmental interest are at very shallow depths below the Earth’s surface. High quality engineering investigations require the accurate location and characterization of these targets prior to the initiation of engineering projects. Subsurface geophysical imaging techniques represent an ideal set of tools to achieve those objectives. Geophysical subsurface imaging methods provide solutions to a wide range of engineering and environmental problems: geotechnical site characterization for building projects such as bridges, dams, and power plants; landslide and ground subsidence hazard detection; type and strength of building materials; safe disposal of chemical and nuclear waste; protection of soil and groundwater; location of archeological artifacts; and forensic engineering investigations.. To assure the active involvement of all students in the learning process, we will utilize an interactive learning/teaching approach. The central theme of this approach involves the application of information and ideas derived from reading assignments toward the development of answers to questions that are designed to stimulate critical thinking. Students will be expected to participate in class discussions aimed at exploring ideas relating to topics introduced in the reading assignments and supplemental activities provided by the instructor.
