Features

  • Shows how water resources systems in karst terrain can be planned to minimize negative and to maximize positive environmental impacts
  • Shows how dams and reservoirs in karst is risky task – reservoirs may fail to fill despite the best engineering practice was applied
  • Discusses modified and regulated natural surface and underground water flows, due to dam construction in karstic areas
  • Covers both rehabilitated and redesigned dams, reservoirs and grout curtains in karst
  • Shows how deep caverns and underground flows can be investigated and properly rehabilitated by application of specific and sophisticated investigation and sealing methods, only

Summary

Karst terrains have been modified and adapted through a range of human activities as the need for flood control, irrigation, food production, hydropower production and other resources has increased. Successful reclamation projects require construction of dams and reservoirs. Karst terrains present the most complex working conditions for dam foundation and realization of safe reservoir space. Practical engineering solutions are extremely complex and the need for successful solution requires serious investigations and the cooperation of a wide spectrum of scientists and engineers. A wealth of data on dam projects in karst has been collected and presented in this book. Since reservoirs in karst may fail to fill despite extensive investigations and remediation treatment the book includes a description of failures as well.
