Karst features discovered during motorway construction in Slovenia

 Major motorway construction is taking place in Slovenia. Almost half the country is karst and many of the new roads are in such terrain. Karst specialists are involved in road design. They explore underground karst systems and suggest how best to preserve the most important ones. These experts also provide advice on ways of protecting karst groundwater and on aspects of road construction in karst. The karst features encountered during construction provide valuable information about the development of karst systems. Received: 8 April 1996 · Accepted: 4 February 1997
