Groundwater is a valuable source of freshwater in coastal areas. The groundwater flux in coastal aquifers generally occurs in two processes: seawater intrusion (SWI) and submarine groundwater discharge (SGD). SWI, the subsurface movement of seawater into freshwater aquifers, is a natural phenomenon in coastal areas. As a result of SWI, the salinity of groundwater in the aquifer increases, thereby reducing the availability of freshwater in coastal areas. The total efflux (including fresh groundwater and circulating seawater) to the sea is commonly referred to as SGD. SGD is an important source of freshwater, nutrients, metals, and carbon to the ocean, thereby affecting coastal water quality and ecosystems. The study of the hydrological behaviors of these two processes in coastal aquifers is beneficial for the sustainable management of marine and groundwater resources in coastal areas.
Groundwater Contamination in Coastal Aquifers: Assessment and Management first describes groundwater contamination in coastal aquifers and then delves into specific topics surrounding various hydrogeochemical processes. Next, the book covers case studies of groundwater quality assessment using recent techniques, explains the various pollutants and contaminants in coastal aquifers, and covers management and remediation methods to control contamination in coastal aquifers. This key reference encompasses various topics in broader perspectives on groundwater contamination in coastal aquifers, providing a significant contribution to the field of hydrogeology. - Presents global case studies that show the reader how this issue is affecting sites around the world - Includes a remediation plan that solves problems surrounding the management of groundwater, water treatment techniques, and the management of available groundwater resources - Provides advanced techniques that can be applied and used as methodologies for solving groundwater issues
GIS and Geostatistical Techniques for Groundwater Science provides a detailed synthesis of the application of GIS and geostatistics in groundwater studies. As the book illustrates, GIS can be a powerful tool for developing solutions for water resource problems, assessing water quality, and managing water resources. Beginning with an introduction to the history of GIS and geostatistical techniques in groundwater studies, the book then describes various spatial techniques, including case studies for various applications, from quality assessment, to resource management. This book assembles the most up-to-date techniques in GIS and geostatistics as they relate to groundwater, one of our most important natural resources. - Provides details on the application of GIS and statistics in groundwater studies - Includes practical coverage of the use of spatial analysis techniques in groundwater science - Bridges the gap between geostatistics and GIS as it relates to groundwater science and management - Offers worldwide case studies to illustrate various techniques and applications in addressing groundwater issues
