Geologists and geographers study how to develop how and where karst develops and how sinkholes form, but engineers must use this information to develop karst terrane. Over the past ten years, these multidisciplinary conferences on the applied aspects of karst hydrogeology and engineering have been successful in bringing together engineers, geologists, other scientists and government regulators who must safely establish human infrastructure on karst terrane whilst protecting the environment. The essences of these conferences has always been communciation between geologists and engineers with an emplasis on practical applications and case studies. This text contains the proceedings of the fifth conference on karst geohazards. It presents 65 papers that cover topics such as: groundwater contamination through sinkholes and the karst surface; stormwater drainage and flooding problems; and foundation considerations and improvements in karst.

Ground-penetrating radar (GPR) is a rapidly developing field that has seen tremendous progress over the past 15 years. The development of GPR spans aspects of geophysical science, technology, and a wide range of scientific and engineering applications. It is the breadth of applications that has made GPR such a valuable tool in the geophysical consulting and geotechnical engineering industries, has lead to its rapid development, and inspired new areas of research in academia. The topic of GPR has gone from not even being mentioned in geophysical texts ten years ago to being the focus of hundreds of research papers and special issues of journals dedicated to the topic. The explosion of primary literature devoted to GPR technology, theory and applications, has lead to a strong demand for an up-to-date synthesis and overview of this rapidly developing field. Because there are specifics in the utilization of GPR for different applications, a review of the current state of development of the applications along with the fundamental theory is required. This book will provide sufficient detail to allow both practitioners and newcomers to the area of GPR to use it as a handbook and primary research reference.*Review of GPR theory and applications by leaders in the field*Up-to-date information and references*Effective handbook and primary research reference for both experienced practitioners and newcomers
