oa Geophysical measurements as efficient tools for hydrogeological investigations

In a number of regions the endangering of groundwater reservoirs has been increased considerably by emerging of extensive residential areas in the neighbourhood of big cities or by means of accidents during the transport of dangerous goods. By this for water supply of a region hydrogeological investigations of water resources have become much more significant in recent years. Detailed knowledge of hydrogeological conditions is not only important for estimation of aquifer capacity but also an essential requirement for effective measures of protection and redevelopment.
