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.

A definitive guide, this book focuses on the design and construction of water infrastructure projects within karst formations and provides engineering approaches for preventing and mitigating their environmental problems. It features 200 figures, investigative techniques, practical design solutions, case studies with failure analysis, criteria prop
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. To improve 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.
Developments in Geotechnical Engineering 6: Dams, Dam Foundations, and Reservoir Sites explores the design and construction of dams and reservoirs, and the foundations on which they rest. It discusses the theory and practice of geology and geophysics as they are applied to the study of proposed sites on which to build dams and reservoirs, the measures taken to ensure the continued safety of a dam during construction, and geological processes and features of foundations. Comprised of 10 chapters, this volume begins with an overview of the geotechnical aspects of planning and construction of dams and reservoirs, along with the origin, nature, and magnitude of problems associated with the foundation materials to be used. It then looks at the geological classification of natural substances and the strengths of these substances in terms of their origin, fabric, and mineralogy; excavation and filling of valleys; the influence of geologic structure in the development of erosional and depositional features in valleys; and the flow of water (seepage) beneath dams and around abutments. The reader is also introduced to groundwater hydrology as it relates to the movement of water through anisotropic materials beneath standing or running bodies of water at the Earth's surface and beneath dams; the mechanics of dam foundations; and excavations and dam construction in unconsolidated deposits. This book will be of interest to geologists, geophysicists, and engineers, as well as those involved in hydrology, geosciences, and rock and soil mechanics.
The area of Eastern Herzegovina is one of the most karstified regions in the world. Deep karst, sinking rivers, underground flows, temporary flooded karst poljes and lack of arable land is main natural property of the region. Due to two kinds of misfortune, flood and drought, people have emigrated from this region searching for a better life. The book contains new scientific data and engineering experience collected during more than 100 years of investigations and construction. To provide optimum water management and economic development, thousands of new data are collected and presented in the book. Necessity for balance between regional development and preservation of nature was one of the important request.
Focusing specifically on the management of karst environments, this volume draws together the world’s leading karst experts to provide a vital source for the study and management of this unique physical setting. Although karst landscapes cover 12% of the Earth’s terrain and provide 25% of the world’s drinking water, the resource management of karst environments has only previously received indirect attention. Through a comprehensive approach, Karst Management focuses on engineering issues associated with surface karst such as quarries, dams, and agriculture, subsurface topics such as the management of groundwater, show caves, cave biota, and geo-archaeology projects. Chapters that focus on karst as an integrated system look at IUCN World Heritage sites, national parks, policy and regulation, measuring systematic disturbance, information management, and public environmental education. The text incorporates the most up-to-date research from leading karst scientists. This volume provides important perspectives for university students, educators, geoengineers, resource managers, and planners who are interested in or work with this unique physical landscape.
This book covers advances in the field of karst from a variety of perspectives to facilitate knowledge and promote interaction between disciplines. New methods are addressed that advance data collection, analysis, and interpretation in a wide range of karst contexts. Case studies are presented to provide examples of advancing science. Issues addressed include karst hydrogeology (water resources assessment, groundwater pollution and protection), methods to study karst aquifers (based on hydrodynamic, hydrochemistry, isotopes, dye tracing, geophysical surveys, and modeling techniques), karst geomorphology and landscape, mining and engineering in karst media (tunnels, dams, etc.), and karst cavities (touristic caves, natural heritage). This book is a resource for scientists around the world to compare problems, results, and solutions. Likewise, the examples included are used in policy decision making in karst regions. Finally, the contributions are used as a tool for university teaching.
