Coastal Hydrogeology

Water resources are of enormous societal and ecological importance. In coastal areas, they are under ever greater pressure due to population growth, more affluent lifestyles, food production and the growing tourism industry. Changes to the coastal landscape, through urbanisation and land reclamation, and by natural processes such as climate change and sea level rise, modify the interaction between seawater and groundwater and put water resources at risk. This comprehensive volume covers both theory and practice of coastal hydrogeology. It discusses hydrochemistry; submarine groundwater discharge; groundwater management; palaeo-hydrology; land reclamation; climate change and sea level rise; and mathematical models of variable-density flow. With its up-to-date coverage and numerous case studies that illustrate practical implications, it is perfect for students, practitioners, managers and researchers who wish to develop an in-depth understanding of topics relevant to sustainably managing coastal groundwater resources.

Jimmy Jiao is a Professor of Hydrogeology in the Department of Earth Sciences at The University of Hong Kong and has over twenty years of teaching and research experience in various topics in coastal hydrogeology. He was the 2011 recipient of the John Hem Excellence in Science and Engineering Award from the National Groundwater Association for outstanding scientific or engineering contributions to the understanding of ground water. Dr Jiao is a Fellow of the Geological Society of London, the Geological Society of America, and the American Society of Civil Engineers. He has provided consultancy services to industry and government organizations regarding various coastal groundwater issues. Dr Jiao was an Associate Editor (2004–08) and Editor (2008–15) of the Hydrogeology Journal and Associate Editor (2002–08) for Groundwater. Vincent Post has nearly twenty years of professional experience in coastal hydrogeology. He completed his Ph.D. on groundwater salinization in the Netherlands, and then worked on projects in coastal zones around the world, including Portugal, Kiribati, and Australia. His expertise spans a broad range of topics, which include numerical modeling, hydrochemistry, measurement techniques and freshwater resource management. Dr Post has published extensively on coastal groundwater flow and chemical processes. He was an Editor of the Hydrogeology Journal (from 2010 to 2015) and is an Associate Editor for the Journal of Hydrology. He is also actively involved in the organization of the Salt Water Intrusion Meeting series that saw its fiftieth anniversary in 2018.

Review :
'This book presents a systematic and comprehensive approach to understanding coastal groundwater and gives readers a balanced examination of almost all important facets of coastal hydrogeology, ranging from palaeo groundwater issues in the recent geological past to future behaviour of coastal aquifers in response to climate change and sea level rise. Numerous international case studies from coastal aquifers cultivate reader understanding of the occurrence, movement and hydrochemistry of coastal groundwater in a variety of geologic settings. I am delighted to have this excellent book on my shelf and believe it will become a classic. I have no hesitation in recommending it as a 'must use' book to all those who work in any aspect of groundwater in the coastal environment.' John Cherry, University of Guelph 'The reader of Jiao and Post's book will find excellent chapters from the principles of hydrology and hydrodynamics to highly practical issues of coastal hydrogeology, complementary to the genetic knowledge of aquifers. The book provides the knowledge and background necessary for all researchers, engineers and practitioners dealing with coastal issues, including groundwater resources, land use, environmental values and ecological services.' Emilio Custodio, Polytechnic University of Catalonia, Barcelona 'At last - a readable and comprehensive compilation of the principles, analytical solutions and literature relevant to coastal groundwater. Jiao and Post have done an incredible job of summarising and discussing the diverse and voluminous literature on coastal hydrogeology in a highly readable book. Basic principles such as equivalent freshwater head and Darcy's law in variable density flow are clearly explained and illustrated. Topics covered range from salt water intrusion, submarine groundwater discharge, tidal dynamics and geochemistry to land reclamation, sea level change and relict (palaeo) salt water in coastal aquifers, with interesting historical insights included throughout. A final chapter pulls together many of the concepts in a discussion of coastal aquifer management and seawater intrusion control. This book is essential for anyone interested in groundwater in coastal areas.' Mary P. Anderson, University of Wisconsin, Madison 'Coastal groundwater presents unique challenges to hydrogeologists, both in its vulnerable position squeezed between land and sea and in the physical and chemical complexities created by variations in density, sources of contamination and characteristic coastal forcings. As pressures on coastal water resources rise with increasing demand, changes in climate and sea-level rise, careful management of coastal groundwater is a greater priority than ever. This book is a timely contribution that provides both a broad overview and a thorough dive into fundamental and emerging topics in the field. With a mix of theory and application, this will be a valuable resource for researchers, practitioners and managers looking to address the coastal water challenges of the coming decades. Holly Michael, University of Delaware 'A timely, unusual, and valuable resource … Figures illustrating important aspects of these concepts abound, and the authors keep advanced mathematics to a minimum, making the book accessible and readable. This volume will be helpful in the classroom and as a secondary resource for those interested in hydrogeology.' M. S. Field, Choice 'Coastal Hydrogeology is a well written and comprehensive monograph that is founded in deep understanding and practical experience …The book has a global feeling and is urban-aware; coastal megacities are often the locus of the problems.'
