This book was released on 2006 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years water quality issues have become apparent in coastal areas of the Lower Burdekin. Longer term, steadily rising groundwater salinity levels have been reported in bores in the Airdmillan Road area of the North Burdekin Water Board (NBWB). The Airdmillan Road area is close to the coast and the environment surrounding the area is a complex mix of hydrological features. Groundwater and surface water are used for irrigation of sugarcane. Lack of pumping volumes is a severe impediment to allow both whole-of scheme and on-farm water management. The current level of available data on groundwater & surface water pumping and crop water requirements is not sufficient to show how each of these factors contribute to the overall hydrology and salinity in the area. This report briefly describes the extent and cause of the problem to help support development of a management plan for sustainable groundwater resources in the area. Despite the lack of data it is believed that the main cause of increasing groundwater salinity is the volume of water extracted from bores in the area resulting in upwelling / upconig (i.e. movement of saline water from deeper in the aquifer to shallower depths). A fine balance between pump location, pumping volume, and pump depth must exist to ensure water quality is not degraded. We strongly recommend that further work be undertaken to measure the amount of groundwater pumped and surface water applied for irrigation. This work could then be used to identify the major drivers of water quality deterioration in the area and ultimately support development of a regional management plan built on more robust knowledge of the local hydrology.

Download or read book Saline Groundwater Surface Water Interaction in Coastal Lowlands written by J.R. Delsman and published by IOS Press. This book was released on 2015-05-07 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Coastal aquifers serve as major sources for freshwater supply in many countries around the world, especially in arid and semi-arid zones. Many coastal areas are also heavily urbanized, a fact that makes the need for freshwater even more acute. Coastal aquifers are highly sensitive to disturbances. Inappropriate management of a coastal aquifer may lead to its destruction as a source for freshwater much earlier than other aquifers which are not connected to the sea. The reason is the threat of seawater intrusion. In many coastal aquifers, intrusion of seawater has become one of the major constraints imposed on groundwater utilization. As sea water intrusion progresses, existing pumping wells, especially those close to the coast, become saline and have to be abandoned. Also, the area above the intruding seawater wedge is lost as a source of natural replenishment to the aquifer. Despite the importance of this subject, so far there does not exist a book that integrates our present knowledge of seawater intrusion, its occurrences, physical mechanism, chemistry, exploration by geo physical and geochemical techniques, conceptual and mathematical modeling, analytical and numerical solution methods, engineering measures of combating seawater intrusion, management strategies, and experience learned from case studies. By presenting this fairly comprehensive volume on the state-of-the-art of knowledge and ex perience on saltwater intrusion, we hoped to transfer this body of knowledge to the geologists, hydrologists, hydraulic engineers, water resources planners, managers, and governmental policy makers, who are engaged in the sustainable development of coastal fresh ground water resources.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM). Groundwater management is a formidable challenge, one that remains one of humanity’s foremost priorities. It has become a largely non-renewable resource that is overexploited in many parts of the world. In the 21st century, the issue moves from how to simply obtain the water we need to how we manage it sustainably for future generations, future economies, and future ecosystems. The focus then becomes one of understanding the drivers and current state of the groundwater resource, and restoring equilibrium to at-risk aquifers. Many interrelated dimensions, however, come to bear when trying to manage groundwater effectively. An integrated approach to groundwater necessarily involves many factors beyond the aquifer itself, such as surface water, water use, water quality, and ecohydrology. Moreover, the science by itself can only define the fundamental bounds of what is possible; effective IGM must also engage the wider community of stakeholders to develop and support policy and other socioeconomic tools needed to realize effective IGM. In order to demonstrate IGM, this book covers theory and principles, embracing: 1) an overview of the dimensions and requirements of groundwater management from an international perspective; 2) the scale of groundwater issues internationally and its links with other sectors, principally energy and climate change; 3) groundwater governance with regard to principles, instruments and institutions available for IGM; 4) biophysical constraints and the capacity and role of hydroecological and hydrogeological science including water quality concerns; and 5) necessary tools including models, data infrastructures, decision support systems and the management of uncertainty. Examples of effective, and failed, IGM are given. Throughout, the importance of the socioeconomic context that connects all effective IGM is emphasized. Taken as a whole, this work relates the many facets of effective IGM, from the catchment to global perspective.

Download or read book Coastal Management in Australia written by Nick Harvey and published by University of Adelaide Press. This book was released on 2010 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: The coast is one of our most valuable assets but how is it being treated and what is being done to look after it? COASTAL MANAGEMENT IN AUSTRALIA is the first book to provide a comprehensive overview of this important subject. Interesting case studies are used to illustrate human impact on coastal processes as well as demonstrating the global significance of the coast and the international imperative to manage it properly. COASTAL MANAGEMENT IN AUSTRALIA introduces the background to the various coastal management systems operating in Australia and illustrates these with 'real world' examples from the different states and territories. Since this book was first published yet another parliamentary inquiry has been added to some 30 years of national inquiries into coastal management, with further calls for national co-ordination. In addition, the Australian government has focused attention on the potential risks of climate change for the Australian coast. Both authors have national and international coastal expertise; significant academic teaching experience in coastal processes and coastal management; coastal planning and policy skills; and have extensive government expertise in coastal management.

Download or read book Groundwater Resources of the World and Their Use written by Igorʹ Semenovich Zekt︠s︡er and published by . This book was released on 2004 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph represents many years of groundwater data accumulation by a large number of noted hydrogeologists located throughout the world. It represents a multicultural approach to groundwater resources and their use. As a result, many of the fundamental concepts in hydrogeology are interpreted slightly differently in other countries. In fact, there are a number of hydrogeologic phenomena introduced that for the most part have not been presented internationally. Since various cultures review the science of hydrogeology with their own nuances, a substantial effort was made to provide classic references in the science of hydrogeology. The focus of the monograph was to present data and scientific principals, which are relevant to groundwater use in each of the countries. This monograph represents a major undertaking by hydrologists and hydrogeologists around the world. Although the fundamental groundwater resource data may change slowly over time, the groundwater use data is rapidly changing. Consulting hydrogeologists, engineers, chemists, geologists, biologists, health officials, and government environmental administrators will find this baseline document of substantial value. It is fully anticipated that this book will serve as the first addition of a series on groundwater resources of the world and their use.
