Detection of Water Caused Channels and Voids in Loos Soils
2014
2010 was a wet year in Hungary. The heavy rains caused serious damages, especially in loose soils. Two case studies are introduced, how geophysical investigations are supplementing the geotechnical studies to detect water damages. In the first case the influence of successive rainwater on loess area was investigated, secondly the geological structures susceptible to river jetting were looked for alongside the River Danube. The research tool primarily was GPR to look for near surface water caused channels and sinkholes and carefully planned 3D resistivity measurement was used to find sandy aquiferous structures on water jet area.
