ABSTRACT
The first use of geophysical methods in karst dates back about 60 years. These methods have been included as an integral part of complex hydrogeological and geotechnical investigations for the past 40 years for the needs of electric energy development, for water supply, and for various other engineering projects [1-9]. In parallel to this general course of affirmation, geophysical methods’ adjustment to specific karst terranes has also been improved. During this period much outstanding geophysical work related to hydrogeological problems in Dinaric karst has been performed. The monograph Geophysics in the Karst, written by Arandjelovi in 1976 [4], has been handled in such a way as to provide insight into the possible uses to which geophysical methods can be put to solve diverse geological, hydrogeological, engineering geological, and geotechnical problems in karst. However, no geophysical method has been developed yet for reliably determining the spatial position of underground cavities and waterflows, especially in cases when these karst forms occur at considerable depths but are of no considerable size.
