Results of applying the georadiolocation method to estimate snow volume in small avalanche assemblages on Sakhalin Island

Abstract

In this paper, the authors present the results of snow volume estimation in small avalanche accumulations on Sakhalin Island using GPR. Sakhalin Island using GPR. As a result of using the GPR method, data on snow cover height, snow volume and density on the slope were obtained. The values obtained using GPR correlate well with data from pits and observations from the Nevelsk weather station, which is located at a close altitude. GPR was modified to complete the study. We used metal markers in the control points to clarify the height of layers when linking them to radarograms. GeoScan32 software was used to determine the dielectric permittivity of the snow cover. The application of the georadiolocation method allows to safely and accurately estimate the snow volume in avalanche accumulation.
