Book Description
In Karst areas, sinkholes are a major geohazard that creates damage and economic loss to building and civil infrastructure. The main goal of the proposed study is to develop a probabilistic spatio-magnitude sinkhole susceptibility model that predicts the potential of sinkhole occurrence on a regional scale. The dissertation presents statistical techniques such as frequency ratio (FR) and logistic regression (LR), and a machine learning technique such as artificial neural network (ANN) to develop the sinkhole hazard models. The study area was limited to the East Central Floria (ECF) region. Seven hydrogeological factors were identified as key contributing factors to sinkhole occurrence and they were used as input variables to the sinkhole hazard model. The seven factors include hydraulic head difference between surficial and upper Florida aquifers, groundwater recharge rate to the upper Floridan aquifer, soil permeability, overburden thickness, surficial aquifer system (SAS) thickness, intermediate aquifer system (IAS) thickness, and proximity to karst features. Both FR and LR were used to construct the spatial prediction models for sinkhole susceptibility mapping. In addition, ANN was employed to develop a probabilistic spatio-magnitude sinkhole hazard model. The prediction accuracy of all models was validated by area under the receiver operating characteristic (ROC) curve (AUC) analysis. Subsequently, the probabilities of location and size of the sinkhole are computed and mapped on a regional scale by Geographical Information System (GIS) techniques.

Book Description
"Sinkholes and Subsidence" provides a twenty-first century account of how the various subsidence features in carbonate and evaporite rocks cause problems in development and construction in our living environment. The authors explain the processes by which different types of sinkholes develop and mature in karst terrains. They consider the various methods used in site investigations, both direct and indirect, to locate the features associated with these hazards and risks, highlighting the value of hazard mapping. Various ground improvement techniques and the special types of foundation structures which deal with these problems are covered in the second half of the text. This book is supplemented with a wealth of actual case studies and solutions, written by invited experts.

Book Description
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.

Book Description
This practical training guidebook makes an important contribution to karst hydrogeology. It presents supporting material for academic courses worldwide that include this and similar topics. It is an excellent sourcebook for students and other attendees of the International Karst School: Characterization and Engineering of Karst Aquifers, which opened in Trebinje, Bosnia & Herzegovina in 2014 and which will be organized every year in early summer. As opposed to more theoretical works, this is a catalog of possible engineering interventions in karst and their implications. Although the majority of readers will be professionals with geology/hydrogeology backgrounds, the language is not purely technical making it accessible to a wider audience. This means that the methodology, case studies and experiences presented will also benefit water managers working in karst environments.

Book Description
The book presents an overview of the main hazards affecting karst, including collapse and subsidence phenomena, hydrological hazards and human-induced geohazards. Consideration is also given to the problems of geohazard management in karst. The geological and hydrological properties of karst terrains make them among the most fragile in the world and pose serious problems for land managers. Sustainable development in these terrains requires efforts to limit geohazards of anthropogenic origin and to recognize and mitigate against those of natural origin. Aimed at providing the reader with worldwide case studies, the contributions cover a range of geological and morphological settings. Geographically, the fourteen papers discuss very different karst areas, from North America, the Caribbean and Asia to several karst areas in Europe, including the British Isles, Spain, France and Italy.

Book Description
Below the live oaks, palm trees, cypress swamps, and springs, water is slowly wearing away the limestone bedrock of Florida. The erosion is often unseen, and over time it can result in shocking cave-ins like the destructive spectacle of the 1981 Winter Park sinkhole. Florida Sinkholes--the first comprehensive book on the subject--is an easy-to-follow guide to understanding how sinkholes form and what to do about Florida's sometimes pockmarked landscape. City planners, construction managers, developers, and homeowners alike will find this book invaluable because of the heavy impact and increasing frequency of sinkhole formation in the state. Amateur geologists will be fascinated by the subtle forces of nature that can make solid rock disappear. Tackling the problem of sinkholes in useful detail, this book packs an abundance of sound scientific fact into frank, readable language. Learn about the captivating workings of karst, a term for the swiss cheese-like formations of soluble rock that underlie the peninsula. Discover current state-of-the-art approaches to mapping sinkholes and subsurface voids. Review such practical concerns as structural damage, repairs, insurance problems, and management of karst lands. Examine case studies of several notable sinkholes and sinkhole events. Even before you've finished reading, you may find yourself itching to get out and visit these intriguing marvels of Florida geology for yourself.

Book Description
The limestone region of PR covers about 27% of the island1s surface and has karst features. The karst belt (KB), that part of the northern limestone with the most spectacular karst landforms, covering 65% of the northern limestone, is the focus here. Chapters: geography; features: geomorphological, hydrological, and ecological diversity; nat1l. resources; econ. importance: water, other minerals, ag., forestry, and environ. disturbances; history of intensive use; vulnerable to human activity: cutting vs. paved over forests, draining vs. filling wetlands, conversion vs. trans1n. of land uses, pumping vs. overdrafting aquifers, contaminating vs. poisoning ground water, and surface water pollution; and proposal for transferring KB to the public domain. Color photos.
