The book provides a review of experimental methods and presents the worldwide newest literature regarding chemical substances fluxes via submarine groundwater discharge (SGD). Thus, the book characterizes both the distribution of chemicals in groundwater impacted areas in the Baltic Sea and their fluxes via SGD to the Baltic Sea. This book presents the state of art regarding the SGD and detailed studies on SGD characterization in the Baltic Sea. The Baltic Sea is an example of a region highly influenced by a variety of human activities that affect the ecosystem. It is shown that SGD has been proven to be one of the important sources introducing dissolved substances into the Baltic Sea. The loads of chemical substances delivered to the Baltic sea with SGD have not been quantified so far.

Groundwater management and conservation becomes a more and more important issue in the heavily urbanized coastal zones of the Asia-Pacific region. This volume presents a comprehensive overview of the status of coastal groundwater research in this diverse region. It includes latest methodologies and technologies to assess processes associated with coastal groundwater development. Case studies and local examples from a broad geographical range of continental shoreline and island settings give an understanding of the diversity of coastal aquifers and the groundwater recourses they harbour. Audience: By providing a clearer understanding of the hydrogeological and hydrochemical processes, this volume offers a critical tool to coastal researchers, geoscientists in related fields, water engineers, groundwater managers and decision makers as it illustrates the human and environmental impacts on coastal groundwater resources and the relationship to coastal zone management strategies and the development of sustainable management approaches.

In 2000, the IAEA and UNESCO jointly developed an initiative to assess methodologies and the environmental importance of submarine groundwater discharge (SGD) for coastal zone management. Under that mandate, a Coordinated Research Project was commissioned to test the application of recently developed nuclear and isotopic techniques suitable for quantitative estimation of various components of SGD. This publication highlights several methods of SGD assessment, carried out during a series of five intercomparison experiments in different hydrogeologic environments. It reviews the scientific and management significance of SGD as well as measurement approaches, and presents the results of the intercomparison experiments.

Historically, water has been treated as an inexhaustible resource. However, with the growth of population and development of industry and agriculture, freshwater demand has increased drastically, and its shortage felt in roughly 60% of the Earth. As early as 1931, renowned Russian scholar A.P. Karpansky wrote: "Water is not only a mineral resource, not only a means for developing agriculture. Water is a real culture bearer, it is a living blood, that creates life where there was none". Groundwater and the Environment: Remediation Applications and the Global Community covers one of the most important ecological problems - the impact on the environment of intensive groundwater pumping out. Drawing on more than a quarter century of study, Zektser analyses and makes conclusions about groundwater exploitation throughout the world. He focuses on the close connection of groundwater to the environment - its affect on surface water streams, reservoirs, seas, landscapes, and vegetation. The author demonstrates the importance of groundwater to the potable water supply, and its interaction with the environment. He stresses the significance of groundwater as a mineral resource. He provides techniques for assessing and mapping natural groundwater resources and develops these principles for studying water and hydrochemicals in coastal zones. In the last twenty years, the global awareness of groundwater as one of the most important natural resources has grown. Any changes in the groundwater causes changes in the environment. Groundwater and the Environment: Remediation Applications and the Global Community increases your ability to predict the possible changes to the environment and to follow the principle: "When using - protect, when protecting - use!"

Most large urban centres lie in coastal regions, which are home to about 25% of the world's population. The current coastal urban population of 200 million is projected to almost double in the next 20 to 30 years. This expanding human presence has dramatically changed the coastal natural environment. To meet the growing demand for more housing and other land uses, land has been reclaimed from the sea in coastal areas in many countries, including China, Britain, Korea, Japan, Malaysia, Saudi Arabia, Italy, the Netherlands, and the United States. Coastal areas are often the ultimate discharge zones of regional ground water flow systems. The direct impact of land reclamation on coastal engineering, environment and marine ecology is well recognised and widely studied. However, it has not been well recognised that reclamation may change the regional groundwater regime, including groundwater level, interface between seawater and fresh groundwater, and submarine groundwater discharge to the coast. This book first reviews the state of the art of the recent studies on the impact of coastal land reclamation on ground water level and the seawater interface. Steady-state analytical solutions based on Dupuit and Ghyben-Herzberg assumptions have been derived to describe the modification of water level and movement of the interface between fresh groundwater and saltwater in coastal hillside or island situations. These solutions show that land reclamation increases water level in the original aquifer and pushes the saltwater interface to move towards the sea. In the island situation, the water divide moves towards the reclaimed side, and ground water discharge to the sea on both sides of the island increases. After reclamation, the water resource is increased because both recharge and the size of aquifer are increased. This book then derives new analytical solutions to estimate groundwater travel time before and after reclamation. Hypothetical examples are used to examine the changes of groundwater travel time in response to land reclamation. After reclamation, groundwater flow in the original aquifer tends to be slower and the travel time of the groundwater from any position in the original aquifer to the sea becomes longer for the situation of coastal hillside. For the situation of an island, the water will flow faster on the unreclaimed side, but more slowly on the reclaimed side. The impact of reclamation on groundwater travel time on the reclaimed side is much more significant than that on the unreclaimed side. The degree of the modifications of the groundwater travel time mainly depends on the scale of land reclamation and the hydraulic conductivity of the fill materials.

Sustainable management of water resources is quickly increasing in importance on a global scale. An important piece of the puzzle is the characterization of marine water and determining its importance to geochemical budgets. To do this, submarine groundwater discharges must be carefully studied. Comprehensively exploring the subject, Submarine G
