GPR results for indicating layers of snow strata

The authors of this article describe the results GPR tests for indicating layers snow strata and determining their properties, allowing forecasting avalanche hazards. were carried out during winter season 2021/2022. Trenches dug in snow, wall which long metal rods (markers) installed, are reflectors make it possible to distinguish boundaries on radarogram. As a result conducting sounding cover, radarograms obtained, layered structure can be read. Using GeoScan32 software, dielectric permittivity values obtained 19 with different properties. Correlations between temperature, crystal diameter, layer density, water storage. resulting relationships reveal strongest correlations higher correlation coefficient dry than wet snow. from also compared calculated derived number empirical density.
