abstract wenner direct contact method is a method of estimating apparent electrical conductivity (eca) of agricultural soils in situ. this method can be affected by factors such as quality of electrodes in contact with soil, type of employed electric current, moisture content, clay content and compaction of soil. in this research, the effect of electrode type (rod and plate) and electric curren...

The study aimed at comparing the resolution and effectiveness of three-electrode arrays (Wenner-α, Wenner-β, Wenner-γ) in 2D Electrical resistivity method using Numerical analysis geological models. Three synthetic models that simulate block-one dyke water layer were generated RES2DMOD software. inversion used for was based on smoothness-constrained least-square which carried out with RES2DINV....

Linear Polarisation Resistance (LPR) can provide a direct evaluation of the instantaneous rate of corrosion. However it has the disadvantage of requiring a localised breakout of the concrete cover to provide an electrical connection to the steel reinforcement. This paper describes an adaptation of the LPR method and the four-point Wenner resistivity method to give an evaluation of the rate of s...
