Preliminary field tests to determine the soil water content using resistivity measurements

摘要

Preliminary field tests were carried out in the protected area of Langen Erlen in Basel in order to find a correlation between variations of soil resistivity and variations of the soil water content. The experimental set up is described and the accuracy of the data is evaluated. Data are interpreted using a conceptual physical model in order to determine the infiltration patterns. An inverse relationship between the variations of soil resistivity and the variations of soil water content is used.
