Temperature dependence of the electrical resistivity of water-saturated rocks : Llera, F J; Sato, M; Nakatsuka, K; Yokoyama, H GeophysicsV55, N5, May 1990,... Temperature dependence of the electrical resistivity of water-saturated rocks; discussion and replyPerhaps I missed something in this ...
Caves formed in hard limestone due to groundwater erosion and rainwater infiltration may cause damages of buildings. The electrical resistivity tomography (ERT) with high lateral resolution and low economic cost is a good way to detect the caves, as the electrical resistivity of water-bearing caves...

The main objective of this study is to identify the shallow aquifer and salt/fresh water zone distribution in the study area using geophysical technique represented by electrical resistivity method. As, the electrical resistivity method is considered as one of the most powerful techniques in the ...
ρ is the resistivity in ohms-meter (Ω×m)l is the length of the conductor in meter (m)A is the cross sectional area of the conductor in square meters (m2) It is easy to understand this formula with water pipes analogy:when the pipe is longer, the length is bigger and the ...
Electrical resistivity has been demonstrated to be an effective predictor of various soil hydraulic properties including water content, degree of saturation, and hydraulic conductivity. Standardized laboratory procedures for measuring soil electrical resistivity are based on the use of the Miller soil box ...
