Office of Ground Water Branch of Geophysics SURFACE-GEOPHYSICAL TECHNIQUES USED TO DETECT EXISTING AND INFILLED SCOUR HOLES NEAR BRIDGE PIERS by Gary Placzek and F.P. Haeni U.S. Geological Survey, 11 Sherman Place, U-5015, Storrs, CT 06103 Abstract Introduction Principles of surface-geophysical techniques Equipment and modification ... References cited ABSTRACT Surface-geophysical techniques were used with a position-recording system to study riverbed scour near bridge piers. From May 1989 to May 1993, Fathometers, fixed- and swept-frequency continuous seismic- reflection profiling (CSP) systems, and a ground-penetrating radar (GPR) system were used with a laser-positioning system to measure the depth and extent of existing and infilled scour holes near bridge piers. Equipment was purchased commercially and modified when necessary to interface the components and (or) to improve their performance. Three 200-kHz black-and-white chart-recording Fathometers produced profiles of the riverbed that included existing scour holes and exposed pier footings. The Fathometers were used in conjunction with other geophysical techniques to help interpret the geophysical data. A 20-kHz color Fathometer delineated scour-hole geometry and, in some cases, the thickness of fill material in the hole. The signal provided subbottom information as deep as 10 ft in fine-grained materials and resolved layers of fill material as thin as 1 ft thick. Fixed-frequency and swept-frequency CSP systems were evaluated. The fixed-frequency system used a 3.5-, 7.0-, or 14-kHz signal. The 3.5-kHz signal penetrated up to 50 ft of fine-grained material and resolved layers as thin as 2.5-ft thick. The 14-kHz signal penetrated up to 20 ft of fine-grained material and resolved layers as thin as 1-ft thick. The swept-frequency systems used a signal that swept from 2- to 16-kHz. With this system, up to 50 ft of penetration was achieved, and fill material as thin as 1 ft was resolved. Scour-hole geometry, exposed pier footings, and fill thickness in scour holes were detected with both CSP systems.

POSITION ANNOUNCEMENT: Wold Chair Scholarship Application 2004-2005 Research Opportunities Distinguished Lecturer Series ... Student Organizations The San Andreas Fault. Professor Demian Saffer is trying to determine the 'strength' of large faults like this. Geology is the study of the origin, history and structure of the Earth. Our undergraduate offerings encompass virtually every aspect of the science, with emphasis on current theory, methods and applications. Our graduate program provides training for the M.S. and Ph.D. degrees in many disciplines of the earth sciences, including geology, geochemistry, geophysics, glaciology, paleontology, planetary science and remote sensing. The philosophy of the department is to provide sound training in both theory and field observation, and to couple this background with a thorough education in modern laboratory, quantitative and field techniques required for an understanding of geologic processes.

HOME Design, Manufacture, and Supply Contact Details Examples MAI's Active EM Imaging System is capable of obtaining high resolution images through most geologies to depths over 300 meters. Unlike high resolution seismic, this system permits imaging through blasted rock and into old mine workings. Many minerals, as well as their grade, can be identified directly by their characteristic signatures. Multimetallic steeply dipping pod shaped ore-bodies in highly folded Cambrian strata have recently been imaged to depths in excess of 250 meters with great success.
