Abstract

Measurements of streaming potentials were carried out on rock glaciers and talus slopes in a test site of the southern Swiss Alps. After some theoretical considerations and a brief description of the measurement technique, a method of data treatment in high declivity topography is presented. The results of self-potential prospecting measurements are generally in accordance with the geomorphological observations. In particular, the groundwater runoff is influenced by the occurrence of permafrost, which creates surfaces of water migration partially independent from ground porosity.
