📊 ASTM G57 / IEEE 81 (Apparent Resistivity ρ = 2π a R, Multi-Layer Soil Modeling)

Wenner 4-Pin Soil Resistivity Calculator

Calculate apparent soil resistivity from field 4-pin Wenner electrode array testing under ASTM G57 & IEEE 81: calculate Apparent Resistivity (ρ = 2π a R ohm-meters across pin spacings a = 1 to 30 meters to penetrate deep earth layers), invert apparent readings into 2-layer soil models (top layer thickness h, ρ1, and ρ2), and geotechnical electrical profits.
