Central Blvd, Seismic... Case Study: Delta Geophysics is Selected for One Day Bedrock Seismic Refraction Survey Customer: Default Size: Single 800-foot seismic line Purpose...: Determine rock excavation quantity along a proposed sewer line. The Method: Seismic Refraction The Scope: Single profile using delay-time data reduction. Delta Geophysics contributes... alternative costs for force main versus gravity sewer installation. The Approach Delta Geophysics team opted to use the seismic refraction method. Seismic refraction is one...

Seismic GPR Electrical Resistivy Electromagnetic Seismic Magnetics VLF Micro-Gravity Subbottom Profiling Geophysical Survey Method Seismic OVERVIEW Seismic methods are based upon... the transmission of seismic (acoustic) waves into the subsurface and recording the resulting waveforms at a distance after traveling through the earth. Seismic refraction... two main types of seismic surveys are Refraction and Reflection. The seismic refraction method is based on the measurement of the travel time of seismic waves refracted...

Water Design/Retention Basin Placement The Method: Resistivity & Seismic Profiling The Scope: Bedrock/Sinkhole Characterization Developer benefits from Delta Geophysics ability... sinkholes were found at the Site. The Approach Delta Geophysics team opted to conduct the survey using resistivity profiling rather than seismic methods. Seismic refraction... was selected for the survey because velocity data that has geotechnical meaning would be a by-product of the bedrock/sinkhole survey; additionally seismic was the most cost-effective method...
