2D Resistivity

The resistivity of the ground is related to diverse geological parameters including the rock type, overburden thickness, porosity, fluid content and mineral content.  Determining the ground resistivity is an important tool that assists with shallow geological / hydrogeological modelling.  By designing a survey program that utilises varying geometrical arrays, BRG can map the resistivity changes in the vertical direction, as well as the horizontal direction and generate a 2-dimensional profile of the subsurface.  This technique is very accurate and versatile for mapping complex geology.

 

Temporal Resistivity surveys are also useful for delineating aquifer location and pollution plume mapping, and for archaeological prospection.
