Reflection Seismilogy entails the use of generated parcels of elastic strain energy in rocks measuring the travel time through the rock body from a given seismic source to receivers. This parcels of energy travel as P - and S - waves propagated by compressionaldilational uniaxial strain and pure shear strain respectively. Reflections are caused by the propagation of seismic waves from one earth layer to another of significant Acoustic Impedance Contrast with reflection strength increasing with increasing contrast. Recorded Reflection Seismic Data are received and processed to improve the Signal-Noise Ratio (SNR) of the recorded data by attenuating coherent and incoherent noise and provides information about the nature of the subsurface. Ability to detect shallow faults, bedrock depth mapping, saturated zone mapping and cavity detection makes the shallow seismic reflwction method suitable for groundwater/environmental studies and geotechnical investigation.
