Short summary
In the last decades, geochemical investigations at the springs of rock glaciers have been used to estimate their drainage processes, and the frozen layer is typically considered to act as an aquiclude or aquitard. In this work, we evaluated the hydraulic behavior of a mountain permafrost site by executing a geophysical monitoring experiment. Several hundred liters of salt water have been injected into the subsurface, and geoelectrical measurements have been performed to define the water flow.
