Abstract: Geophysical Previous HitMethodsNext Hit for Site Characterization


Mustafa Saribudak

The primary factor affecting the accuracy of any site characterization effort is the limited number of sample brings, resulting in insufficient spatial sampling to adequately characterize the site. This is the primary reason for the application of surface geophysical Previous HitmethodsNext Hit.

A number of geophysical Previous HitmethodsNext Hit are commonly applied to detailed shallow-depth investigations. These Previous HitmethodsNext Hit are Previous HitelectricalNext Hit, electromagnetic, magnetic, gravity, seismic reflection and refraction, borehole logging, and ground-penetrating radar. Each geophysical method is useful for measuring the vertical and/or lateral distribution of subsurface bodies having differing geophysical properties.

The success of any surface geophysical survey is dependent upon many factors. One of the most important is the competence of the person(s) responsible for carrying out the survey and interpreting the data. An understanding of the theory, field procedures, and Previous HitmethodsNext Hit for interpretation of data, along with an understanding of the site geology, is necessary to successfully complete a geophysical survey. Properly planned, conducted, interpreted, and reported, a geophysical survey can provide a wealth of subsurface information that could not be obtained otherwise.

This presentation is a review of the capabilities and Limitations of basic geophysical Previous HitmethodsTop currently being employed in the environmental industry. In addition. several case studies, including magnetic, gravity, conductivity, time-domain sounding, resistivity, and ground-penetrating radar, will be presented.
