Description
Seismic Refraction investigations are commonly used to determine bedrock depth & rippability.

Seismic Reflection surveys are used to map, detect, & delineate geologic conditions including the bedrock surface, voids, water table and layer geometry (folds).

The Seismic Refraction & Reflection (SRR) system is designed to allow for either seismic refraction or seismic reflection data acquisition. The SRR system, which is designed for shallow surveys, can also be used for detecting voids in large civil structures such as dams (seismic reflection).

Seismic Refraction surveys are used for excavation purposes to map the bedrock depth and evaluation rock rippability. Seismic refraction measurements are applicable in mapping subsurface conditions for various uses including geologic, geotechnical, hydrologic, environmental, mineral exploration, petroleum exploration, and archaeological investigations. Seismic Refraction investigations are commonly used to determine layer thickness and/or the subsurface compressional wave velocity of the overburden and underlying bedrock or to water table, stratigraphy, lithology, structure, and fractures. This inherently shallow technique requires that compressional seismic wave velocities increase with depth so wave refraction occurs.

Seismic Reflection surveys are used to map, detect, and delineate geologic conditions including the bedrock surface, confining layers (aquitards), faults, lithologic stratigraphy, voids, water table, fracture systems, and layer geometry (folds). This methodology requires that the target be sufficiently deep, so that the incoming reflected wave arrives after the surface wave generated from the impact. Near-surface seismic-reflection data are generally high-resolution (dominant frequency above 80 Hz) and image depths from around 20 ft (6 m) to as much as several hundred feet (100+ meters).
