oa Groundwater flow studies by EM and GPR methods for landslide zones prediction

The results of geophysical investigations within zone of development of landslide processes are given. The areas of underground water flows and increased soil moistening are effectively mapped by area survey by method of forming of short-pulsed electromagnetic field (FSPEF). The methods of vertical electric-resonance sounding (VERS) and GPR- sounding allow to determine the depths of bedding of moistening zones, underground water flows, suffusion cavities, karst cavities. This complex of geophysical methods can be used effectively for the operative monitoring and prediction for natural and man-caused dangerous phenomenon’s and processes, that are connected with landslides, karsts depressions, flashes and suffusion removal of grounds. At the site of work are detected and mapped zones of underground flows and increased soil moistening that allows the engineering team to develop effective solutions to prevent landslide processes in the area of the H9 highway (Lviv – Mukacheve).
