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.

Book Synopsis Using Groundwater Responses to Infer Recharge - Part 5 by : D Armstrong
Download or read book Using Groundwater Responses to Infer Recharge - Part 5 written by D Armstrong and published by CSIRO PUBLISHING. This book was released on 1998-01-01 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical methods of assessing the response of groundwater levels to a range of factors, including elastic (barometric and tidal) influences in confined aquifers and recharge to unconfined aquifers due to infiltration of rain and other surface water, are presented. Responses in a confined aquifer to distant recharge events and the associated time lag is discussed. Also covered are responses to changes in storage volume resulting from direct recharge at the outcrop of an unconfined aquifer system both seasonally and on a single recharge event basis. Worked examples and case histories are used to illustrate methods of estimating the amount of recharge at different sites within a catchment. The application of vertical cross-sectional flow nets to the estimation of recharge is presented in the context of recharge/discharge profiles.
Book Synopsis An Integrated Approach to Estimating Groundwater Recharge and Storage Variability in Southern Mali, Africa by : Chris M. Henry
Download or read book An Integrated Approach to Estimating Groundwater Recharge and Storage Variability in Southern Mali, Africa written by Chris M. Henry and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater recharge in southern Mali is investigated using a variety of methods. The aquifer system comprises a surficial unconfined aquifer in laterite that is hydraulically connected by vertical fractures through a sedimentary rock layer to a deep fractured semi-confined aquifer. Observed groundwater storage fluctuations from historical water level data correlate with GRACE satellite terrestrial water storage (TWS) variations, with peaks in September and lows in May; however, soil-moisture corrected GRACE data peaked in November due to the GLDAS model poorly predicting the timing of soil-water storage changes. Recharge modeling using HELP gave an average annual net recharge of 132.2 mm (12.6% of rainfall), comparing well with estimates from historical water level (149.1 mm; 16.4%) and GRACE (149.7 mm; 14.8%) data. Major ion chemistry suggests groundwater is fresh (average TDS of 205 mg/L) and rapidly recharged. d18O and d2H concentrations in groundwater and precipitation indicate July-September rainfall as the recharge source.
Book Synopsis Groundwater Recharge from Run-off, Infiltration and Percolation by : K.-P. Seiler
Download or read book Groundwater Recharge from Run-off, Infiltration and Percolation written by K.-P. Seiler and published by Springer Science & Business Media. This book was released on 2007-09-26 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: To face the threats to the water supply and to maintain sustainable water management policies, detailed knowledge is needed on the surface-to-subsurface transformation link in the water cycle. Recharge flux is covered in this book as well as many other groundwater issues, including a comparison of the traditional and modern approaches to determine groundwater recharge. The authors also explain in detail the fate of groundwater recharge in the subsurface by hydraulic and geologic means, in order to stimulate adapted groundwater-management strategies.

Book Synopsis Groundwater and Society by : Pravat Kumar Shit
Download or read book Groundwater and Society written by Pravat Kumar Shit and published by Springer Nature. This book was released on 2021-03-12 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume advances the scientific understanding, development, and application of geospatial technologies related to groundwater resource management, mapping, monitoring, and modelling using up-to-date remote sensing and GIS techniques. The book further provides a critical analysis of the debates and discourses surrounding groundwater resources and society, illustrates the relationship between groundwater resources and precision agriculture for societal development, and describes novel, region-specific management strategies and techniques for sustainability with case studies. The book is organized into three parts: (I) Groundwater resources and societal development; (II) Groundwater availability, quality and pollution; and (III) Sustainable groundwater resources management. Each section begins with a short introduction that includes an overview of the papers in that section. Individual chapters focus on the core themes of research and knowledge along with some topics that have received lesser attention. The book will be of interest to water resource planners and decision-makers, academic researchers, policy makers, NGOs, and academic researchers and students in Geography, Geophysics, Hydrology, Remote Sensing & GIS, Agriculture, Soil Science, and Agronomy.

Book Synopsis Recharge of Phreatic Aquifers in (Semi-)Arid Areas by : Ian Simmers
Download or read book Recharge of Phreatic Aquifers in (Semi-)Arid Areas written by Ian Simmers and published by Routledge. This book was released on 2017-10-19 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater use is of fundamental importance to meet the rapidly expanding urban, industrial and agricultural water requirements in (semi) arid areas. Quantifying the current rate of groundwater recharge and define its variability in space and time are thus prerequesites for efficient groundwater resource managment in these regions, where such resources are often the key to economic development. Attention focuses on recharge of phreatic aquifers, often the most readily-available and affordable source of water in (semi) arid regions. These aquifers are also the most susceptible to contamination, with the recharge rate determining their level of vulnerability. (Semi) arid zone recharge can be highly variable, the greater the aridity, the smaller and potentially more variable the natural flux. Its determination is an iterative process, involving progressive data collection and resource evaluation; there is also a need to use more than one technique to verify results. Direct, localised and indirect recharge mechanisms from a spectrum of known sources are addressed in the framework of recharge from precipitation, intermittant flow and permanent water bodies. The approach taken for each of these reflects the nature and current understanding of the processes involved. The volume also reviews current recharge estimation challenges, outlines recent developments and offers guidance for potential solutions.
