Another possibility of interpreting seismic refraction data is the refraction-tomography, which is pre-sented in chapter IV. The depth of water table estimated by the refraction test is always greater than the real level of the water. It can be used to derive important details about the geometry of structures and their physical properties. The geophysical property that is measured in seismic refraction is seismic velocity. • CONDUCTING SEISMIC TEST • Seismic Refraction: • The seismic refraction method measures head waves that are refracted along geologic formations below the earth's surface. Such courses and training will help them to know more information about the seismic data processing. Vertical Geophones. Used in the fields of engineering geology, geotechnical engineering and exploration geophysics, seismic refraction traverses (seismic lines) are performed using a seismograph(s) and/or geophone(s), in an array and an energy source. Photograph of a seismic refraction survey Seismic refraction tomogram of a salt diapir in central Utah. P-waves propagate at the highest velocity of any seismic waves and are therefore commonly used to pick the first breaks of seismic waves … These techniques provide detailed Fkirin MA, Badawy S, El deery MF 2016 Seismic Refraction Method to Study Subsoil Structure eol eophys 5: 259 doi: 104172/2381 87191000 259.

Several computer programs are used in processing seismic refraction data including the program FIRSTPIX by Interpex, Ltd., which allows manual or ™ automatic picking of first breaks, the program VIEWSEIS™ by Viewlog Systems, Ltd., which implements the GRM, and the program SeisOpt by Optim LLC for data modeling. Or use it to find and download high-quality how-to PowerPoint ppt presentations with illustrated or animated slides that will teach you how to do something new, also for free. So the travel time curve of this ray is a hyperbola! Explosive seismic source. A seismic source is a device that generates controlled seismic energy used to perform both reflection and refraction seismic surveys. ... test pits, trenches, outcrops, and other geological information. SEISMIC METHODS Introduction: Seismic techniques are commonly used to determine site geology, stratigraphy, and rock quality.
