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
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
Therefore, CPTs were chosen for this study to understand how they can be implemented to assess risk of future sinkhole collapse, or other karst construction concerns, in Central Florida specific soils. By implementing the findings presented in this report, Geotechnical engineers and contractors in central Florida will be able to practically evaluate the size and severity of potential forming sinkhole without the use of additional subsurface geophysical testing. The results of this study hope to eliminate extraneous testing costs, as well as maximize the efficiency of estimating mitigation products and procedures required all while still ensuring a safe design in Central Florida's highly karst areas.
