WebA gravel that is infilled with sand, silt and clay will have a lower hydraulic conductivity than and open framework gravel found in a river bar. Though both are classified as gravel deposits, their hydraulic conductivity may differ by orders of magnitude. WebOct 1, 1998 · Soil type. Black dirt, or soils with high organic content, are usually good conductors because they retain higher moisture levels and have a higher electrolyte level: leading to low soil resistivity. Sandy soils, which drain faster, have a much lower moisture content and electrolyte level. Therefore, they have a higher impedance.
