Section Summary

This section discusses subsurface electrical properties. This is done in three pages. In the first page a brief discussion is given of electrical properties of rocks and soils and current conduction mechanisms in rocks and soils. On the second page the dependency of electrical properties on some common soil properties is discussed and on the last page a table is presented with typical ranges of electrical properties in soils .
