Subsurface Exploration: Engineering Geophysics. 7 components parallel and perpendicular to the surface of the ground, which are known respectively as SH and SV waves. The maximum velocity of an S wave is about 70% of the P wave velocity through the same medium. 3. Rayleigh waves. Abstract. Groundwater is an invisible natural resource.

Confined aquifer Impervious layer. • Recharged by infiltration either Impervious layer. directly on the land surface or in the beds of streams, lakes & oceans. The strength of the field is directly proportional to the average conductivity of the subsurface materials. The system can sound the depth, thickness and conductivity of layers down to m below surface. For applications such as mapping the thickness of aquifers, clay layers and assessing water quality. Chapter 31 Groundwater Investigations Groundwater investigations (a) Introduction The intensity of groundwater investigations depends on project purposes and scope, complexity of site conditions, and availability and accuracy of existing information and records.
