Principles of Karst Hydrogeology


Book Description

This book reviews the hydrogeology of karst systems, starting with the classifications from the applied point of view, and then the hydraulic parameters (porosity, permeability, and transmissivity). It also addresses the karstification process, its resulting forms, and their hydrogeological significance. Besides, the author describes possible models of karstic aquifers and their characterization. The book also explains the classical methods for analyzing hydrograms of karst springs and deepens the analysis of time series, as a preliminary phase to the mathematical simulation of karst aquifers. Finally, it introduces the hydrogeochemical characterization of karst, of the processes involved as well as the possible pollution and protection of karst aquifers. This book is intended to be of interest for professionals in hydrogeology as well as graduate and undergraduate students.







Enhanced Characterization and Representation of Flow Through Karst Aquifers


Book Description

This research report summaries and details the first year of work on a multi-year karst modeling project organized to develop enhanced groundwater modeling capabilities that can be used to effectively manage karst aquifers. Discussed are the three key considerations for modeling karst systems were identified: representation of conduits in flow models, representation of flow dynamics in conduits, and representation of partially filled conduits and the numerical experiments used to identify the limitations and advantages of the three general representations of conduits within groundwater models. A new dual-conductivity MODFLOW-2000 package (DCM) was developed for testing the dual-conductivity approach. A turbulence model was added, the software was validated using simple benchmark problems, and code documentation was completed. Simultaneous demonstrations showed that the modeling tool can be successfully applied in complex applications.




Karst Aquifers - Characterization and Engineering


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.




Frontiers of Karst Research

Karst Aquifer Modeling in North-Central Florida


Book Description

"The Civil and Coastal Engineering Department at the University of Florida was retained by the St. Johns River Water Management District (SJRWMD) to evaluate the dynamic hydraulic response of a karst aquifer in north-central Florida using innovative analyses and quantitative tools. This project was motivated by the need of the SJRWMD to manage water resource caution areas (i.e., areas where existing or future anticipated water resources are deemed insufficient to satisfy current or projected demands over a 20-year planning period) (St. Johns River Water Management District, 2005a, b; Kinser et al., 2006). The area of interest is the springshed that provides for Blue Spring in Volusia County in northeast Florida. The University of Florida retained Southwest Research Institute® in this investigative endeavor. The critical components of the assessment include an evaluation to determine whether MODFLOW-DCM Version 2.0 (Painter et al., 2007) improves existing models, whether the improvements adequately capture the hydraulic dynamics of the karst groundwater flow system, and whether these are useful in groundwater resource management. MODFLOW-DCM is an innovative numerical simulator designed to account for the dynamic interaction between diffuse and conduit flow inherent in karst aquifers. This evaluation also determined whether MODFLOW-DCM could simulate the hydraulic response of a karst aquifer in which conduits are poorly located and characterized."--Introduction.




Geotechnical and Environmental Applications of Karst Geology and Hydrology


Book Description

This text covers topics such as sinkhole formation and regional studies of sinkholes and karst. Issues addressed are taken from the 8th multidiscilinary conference on this subject and chart the characteristics of sinkholes and karst as well as their environmental repercussions.




Karst Hydrogeology, Geomorphology and Caves


Book Description

Karst Hydrogeology, Geomorphology and Caves A Comprehensive Resource Covering All Aspects of Karst Hydrogeology, Geomorphology, and Caves This essential book covers all physical, chemical, and geological aspects of karst science. It reviews current knowledge on hydrogeology, geomorphology and caves in karst, based on the vast existing literature and investigations carried out by the authors worldwide. The different topics are profusely illustrated with color figures and images from all continents and climates, showing the scientific and aesthetic appeal of karst environments. The book covers in a systematic way the significant features of karst rocks, the chemistry and kinetics of their dissolution, the rate and distribution of karst denudation, the unique hydrogeology of karst terrains, the landforms endemic to karst, the morphology of caves and their diverse sedimentary records, and the multiple processes that lead to the formation of underground voids. Overall, the work reflects the increasing recognition of karst as a fundamental part of the Earth’s dynamic systems, and helps readers understand this multidisciplinary field from a holistic and nuts-and-bolts perspective. Some of the ideas discussed within the book include: How karst is gaining importance for human development, because of its valuable resources (groundwater) and associated environmental problems (impacts and hazards) The enormous technological developments achieved in recent years Recent major breakthroughs in the field and their influence on other scientific disciplines The central role played by karst science for understanding and mitigating global environmental issues (global warming, depletion of resources, human-induced hazards) For all scientists working in karst, and for students and lecturers of karst-related programs, this book serves as a valuable all-in-one source. It is also a valuable resource for professional hydrogeologists, the petroleum industry, environmental geologists, and of course speleologists, the last true geographic explorers in the world.
