Download or read book Groundwater Chemical Methods for Recharge Studies Part 2 written by PG Cook and published by CSIRO PUBLISHING. This book was released on 1998-03-01 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: These notes are restricted to those geochemical methods which have been used to quantify rates of groundwater recharge. There have been two main approaches. The first involves the use of mass balances and mixing cell models, mainly using conservative (non-reacting) dissolved species. The methods range in complexity from simple back-of-the-envelope calculations (zero-dimensional chloride mass balance), to complex three-dimensional computer models. The second approach seeks to estimate the age or residence time of the groundwater by measuring compounds which are radioactive, or whose input to the aquifer has been changing over time (chlorofluorocarbons). In this report, the methodology and case examples are described. References to further information on the techniques are also provided.

Download or read book Ground Water Recharge Using Waters of Impaired Quality written by National Research Council and published by National Academies Press. This book was released on 1994-02-01 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: As demand for water increases, water managers and planners will need to look widely for ways to improve water management and augment water supplies. This book concludes that artificial recharge can be one option in an integrated strategy to optimize total water resource management and that in some cases impaired-quality water can be used effectively as a source for artificial recharge of ground water aquifers. Source water quality characteristics, pretreatment and recharge technologies, transformations during transport through the soil and aquifer, public health issues, economic feasibility, and legal and institutional considerations are addressed. The book evaluates three main types of impaired quality water sourcesâ€"treated municipal wastewater, stormwater runoff, and irrigation return flowâ€"and describes which is the most consistent in terms of quality and quantity. Also included are descriptions of seven recharge projects.

Download or read book Estimation of Natural Groundwater Recharge written by I. Simmers and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: In view of the rapidly expanding urban, industrial and agri cultural water requirements in many areas and the normally associated critical unreliability of surface water supplies in arid and semi-arid zones, groundwater exploration and use is of fundamental importance for logical economic development. Two interrelated facets should be evident in all such groundwater projects : (a) definition of groundwater recharge mechanisms and characteristics for identified geological formations, in order to determine whether exploitation in the long-term involves 'mining' of an es sentially 'fossil' resource or withdrawal from a dynamic supply. A solution to this aspect is essential for development of a re source management policy: (b) determination of recharge variability in time and space to thus enable determination of total aquifer input and to quantify such practical aspects as 'minimum risk' waste disposal locations and artificial recharge potential via (e.g.) devegetation or engi neering works. However, current international developments relating to natural recharge indicate the following 'problems' ; no single comprehensive estimation technique can yet be iden tified from the spectrum of methods available; all are reported to give suspect results.

Download or read book Integrated Groundwater Management written by Anthony J Jakeman and published by Springer. This book was released on 2016-08-05 with total page 756 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Artificial Recharge of Groundwater focuses on artificial recharge of groundwater basins as a means to increase the natural supply of groundwater, along with the technical issues involved. Special emphasis is placed on the use of reclaimed municipal wastewater as a source for artificial recharge of groundwater. This book is comprised of 26 chapters organized into five sections. After reviewing the state of the art of artificial recharge of groundwater, the discussion turns to the fundamental aspects of groundwater recharge, including the role of artificial recharge in groundwater basin management, recharge methods, hydraulics, monitoring, and modeling. The next section considers pretreatment processes for wastewater and renovation of wastewater with rapid-infiltration land treatment systems and describes the health effects of wastewater reuse in groundwater recharge. A number of artificial recharge operations using reclaimed wastewater are then highlighted, focusing on cases in various countries including Israel, Germany, Poland, Japan, the Netherlands, and the United States. The remaining chapters look at the extent of contaminant removal by the soil system and the fate of micropollutants during groundwater recharge as well as the legal and economic aspects of groundwater recharge. Research needs for groundwater quality management are also explored. This monograph is written for civil and sanitary engineers, agricultural engineers, hydrologists, environmental scientists, and research scientists as well as public works officials, consulting engineers, agriculturalists, industrialists, and students at colleges and universities.
