Karst Cavity Forms and Their Radio Images Revealed by Comparative Physical Modelling
Main Article Content
Abstract
GPR surveys were conducted to select a safe location for the construction site in a limestone region. Using the theory of similarity of electromagnetic fields, the results of laboratory physical modelling were extended to field data. The survey data were interpreted with high accuracy for decoding underground objects.
The tasks set by the builders were solved on the basis of the geo-radar works: the less and most karst-damaged areas were identified.
