This book shares essential insights on evaporites and their effects on dams and reservoirs. The intensity of the solution and suffusion process in evaporites (gypsum and salt) is much greater than the solution of carbonates, and evaporites are particularly vulnerable at dam and reservoir sites.Moreover, the presence of evaporites in the vicinity of dams or reservoirs often leads to serious problems: numerous dams in countries around the world (e.g. China, Germany, Iran, Iraq, Peru, Russia, Spain, the Unites States, and Venezuela) have been affected by evaporite dissolution problems. Several of these dams were seriously endangered or ultimately abandoned, even though the best available engineering prevention and remediation practices were applied. Conventional geotechnical methods based on treating the underground (e.g. grout curtains) or surface (e.g. protective blankets) were not successful.This book presents and analyzes revealing case studies in this regard. Toimprove geotechnical remediation in connection with preventing seepage from reservoirs situated in evaporites, particularly in gypsum, it puts forward a new chemical solution that, after painstaking laboratory testing, was successfully applied in the field.

The book provides a characteristic of sulfate karst, the features of its distribution and development in the Perm region, based on their own research and generalization of data accumulated in recent years. An updated zoning of the territory is given, partly based on the use of GIS technologies. This book also offers a detailed description of areas with characteristics of geological and hydrogeological conditions for the development of karst and karst phenomena. Besides, it also provides a detailed description of a number of caves, information about specially protected natural areas associated with sulfate karst and new unique objects that need protection. The book describes the influence of karst on economic activity and the ecological situation.The publication is intended for geologists, geographers, ecologists, karst scientists, speleologists, local historians, teachers and students of specialties related to earth sciences, as well as a wide range of karst and cave enthusiasts.
