Webadditional testing to measure the scour potential. Moreover, ER surveys may be used to determine which existing bridges should be closed or closely monitored for scour potential during a flood event. Project Results Preliminary analytical models to predict soil critical shear stress using ER and other soil parameters were constructed. WebIn addition, direct resistivity tests of the soil using the “Wenner four-pin” method indicated a resistivity value of 1800 W-cm, putting the soil in a corrosive category. The analysis of the corrosion deposits on the outside of the pipe by Energy Dispersive X-ray (EDX) showed a high concentration of sulfur in addition to smaller amounts of chlorine.

The most common methods for testing are the Wenner and Schlumberger methods, which measure an apparent resistance with multiple variations in the spacing of the test probes. The figure below ... cowboys grand final winSoil resistivity is a measure of how much the soil resists or conducts electric current. It is a critical factor in design of systems that rely on passing current through the Earth's surface. It is a very important parameter for finding the best location of a transmitter working on low frequiencies (VLF, LF, MF and lower shortwave) as such radio stations usually use ground as counterpole.
