Description

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.

About the Editors

Dr Ian Simmers is Emeritus Professor of Geography at the Free University of Amsterdam. His research interests were in recharge and flow in porous media as applied to the management and protection of wetlands, on which he has published extensively. He is Editor in Chief of the publication series of IAH.

About the Series

IAH - International Contributions to Hydrogeology

The International Association of Hydrogeologists (IAH) serves scientists, engineers and other professionals working in the field of groundwater resource planning, management and protection. IAH has two book series which are produced under the imprint of CRC Press in the Netherlands, part of the Taylor and Francis Group. IAH books have the common purpose of spreading the science and knowledge of hydrogeology and are products arising from IAH’s congresses and meetings, its commissions and networks, as well as a variety of other sources. Information is gathered from highly respected sources and include case studies, regional descriptions, analyses of sub-disciplines and outputs from major international programmes.

International Contributions to Hydrogeology
The second series, International Contributions to Hydrogeology, the ‘blue books’, includes monographs on sub-disciplines of hydrogeology as well as outlets for major international investigatory programmes and collections of papers within a broad theme of international interest.

Selected Papers
The first series is the Selected Papers, often referred to as the ‘green books’. These are collections of papers derived from Congress and other meetings which normally, but not always, were sponsored by IAH. They may also be a collection of papers derived from a programme of investigation that again need not necessarily have enjoyed direct IAH involvement.
