Seismic velocity and rock properties

appliedgeophysics.berkeley.edu

It is observed that seismic waves decrease in amplitude due to spherical spreading and due to mechanical or other loss mechanisms in the rock units that the wave passes through. The attenuation for a sinusoidal propagating wave is defined formally as the energy loss per cycle (wave length) ∆ E/E where E is the energy content of the wave.

ated with water currents and wave attack. Slope face erosion may create rills and gullies, and result in surface sloughing and possibly deep-seated failure (Berg.1993). Erosion control and re-vegetation measures must, therefore, be an integral part of all reinforced soil slope system designs. The type of erosion control
