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.
