oa Small scale correlation between the electrical and the hydraulic conductivity

There has been an ongoing discussion about the relationship between the hydraulic and the electrical conductivity. In order to test this relationship on a small scale a new method for in situ determination of the hydraulic conductivity has been developed at the Department of Earth Sciences. In a series of field tests in a sandy alluvium, estimates of the hydraulic conductivity were obtained in three closely spaced borings together with gamma and electrical logs. The results indicate that there is no evident relationship between the electrical conductivity and the hydraulic conductivity on a small scale.
