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.

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.

Coastal areas face increasing pressures from land use change, developmental activities, shoreline erosion, biodiversity losses and natural calamities. This volume addresses these issues facilitating the integrated analysis of the sustainability of coastal zones. The contributors have tried to focus their respective works on the problems that need urgent attention relevant to present day issues. Coastal Zone Management and its sustainability strategy should safeguard ecological security of the coastal areas, avoid pollution as well as exploitation of living and non living aquatic resources, protecting also the agrarian community and avian population and other floral and faunal breeding grounds. Articles have been selected on the basis of sound scientific findings hoping that it will help in developing meaningful regulations for future sustainable coastal management zone.

Coastal zones are among the world's most densely populated and economically important areas, but these factors put pressure on the often limited available freshwater resources. Global change will undoubtedly increase this pressure through the combined effects of increased population, economic development, rising sea levels, increased evapotranspiration, over-extraction and the salinization of coastal aquifers, decreasing river discharges, and accelerating land subsidence. Saline groundwater exfiltration is a common problem in the coastal zone of the Netherlands, but the hydrological processes and physiographic factors that affect this are not fully understood. The research presented in this book aims to identify the processes and physiographic factors controlling the spatial variability and temporal dynamics of the exfiltration of saline groundwater to surface water, and hence the contribution of saline groundwater to surface water salinity. Topics covered include a paleo-hydrogeological model simulation of the Holocene evolution of groundwater salinity as a result of paleo-geographic changes; surface water salinity dynamics in a densely-drained lowland catchment; hydrograph separation in an agricultural catchment; observations of heads, flow, solute concentration and temperature to constrain a detailed, variable-density groundwater flow and transport model; and a model to simulate the salinity dynamics of exfiltrating groundwater to support operational water management of freshwater resources in coastal lowlands. The book further outlines the implications of these findings for freshwater management in the Netherlands. The book demonstrates that the salinity of groundwater exfiltrating in polders in the Netherlands, and hence surface water salinity, varies on a wide range of spatial and temporal scales.
