Short summary
Different geophysical methods such as electrical resistivity tomography (ERT), seismic refraction tomography (SRT) and multichannel analysis of surface waves (MASW) were jointly used to characterize the internal structure of the Flüela rock glacier, Switzerland. We show that the MASW method can efficiently resolve an ice-rich layer even in presence of a supra-permafrost water flow and noisy data, a situation when SRT may fail. Our results are corroborated by seismic synthetic modelling.
