The Aquares Resistivity System, as an exploration tool for rock dredging applications

Aquares resistivity surveys are proving invaluable to dredging companies and particularly those involved with high risk dredging projects that require the removal of rock in ports, access channels and pipe line trenches throughout the world. The unique ability of the Aquares Resistivity System (ARS) to distinguish different types of rock and clearly define thickness and depth of each of the present geological units is very useful in these applications. This paper provides an insight to the theory of the ARS, a brief comparison between acoustic and geo-electric methods as well a number of case studies of dredging projects involving the use of explosives to remove very hard rock.
