The Multidisciplinary Conference on Sinkholes and the Engineering and Environmental Impacts of Karst, generally called “The Sinkhole Conference,” is the longest-running international conference of its type. Since 1984, engineers, geologists, hydrologists, land managers, biologists, and many others have gathered at these meetings to exchange cutting-edge information on karst and its many benefits and challenges. Abstracts may be submitted until 15 August 2017, after which will be the time to submit your papers to accompany your abstracts. The papers of past Sinkhole Conferences have made those proceedings highly sought and widely cited. We expect the proceedings of the upcoming meeting will be the best yet.
