If you’re interested in the difficulties and challenges of living in karst, you can download the book below for free. It is well illustrated and includes the basics, for those who are not geologists or engineers, or generally not familiar with karst. The authors are from South Africa, so many of the examples are focused there, but the basic processes of how karst forms and is vulnerable to human activities apply internationally.

Book Summary: Large areas of the Earth’s surface are underlain by soluble rocks such as limestone and dolomite. Most of these areas also have concentrated human development because groundwater availability in the subsurface dissolution cavities. Karst processes may cause unstable surface conditions due to sinkholes and surface subsidence’s that develop naturally and also through anthropogenic disturbances such as groundwater lowering and disturbance of surface materials by infrastructure development. These features also connect the land surface to the groundwater in the karst aquifers resulting in groundwater recharge, discharge (springs), and also vulnerability of the aquifer that can result in groundwater pollution. These instability features pose a hazard to human lives and infrastructure and careful assessment of these risks followed by appropriate measures to reduce the risk are necessary to safely live on karst. This book aims to provide a background on karst theory with specific application to investigation methodology linked to different karst environments, hazard determination, and how to mitigate and rehabilitate hazard events.

 

Louis van Rooy retired as associate professor in Engineering Geology and Rock Mechanics at the University Pretoria which he joined in 1985. He started his career in the “dolomite section” of the then Geological Survey of South Africa. His research covers hazards in karst, engineering properties of basic igneous rock in civil engineering infrastructure, and prediction of flow mechanisms through rock masses based on engineering rock mass characterization.

 

Matthys Dippenaar is an associate professor in Engineering Geology and Hydrogeology at the University Pretoria. He joined the university in 2007 following six years working in industry. His research focus is the intermediate vadose zone where air and water fill the void space of intergranular, fractured, and karst systems. His projects incorporate societal and environmental matters as well as establishment of regional groundwater monitoring, and impacts of anthropogenic changes.
