Download or read book Groundwater Modelling in Arid and Semi Arid Areas written by Howard S. Wheater and published by Cambridge University Press. This book was released on 2010-09-09 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Arid and semi-arid regions face major challenges in the management of scarce freshwater resources under pressures of population, economic development, climate change, pollution and over-abstraction. Groundwater is commonly the most important water resource in these areas. Groundwater models are widely used globally to understand groundwater systems and to guide decisions on management. However, the hydrology of arid and semi-arid areas is very different from that of humid regions, and there is little guidance on the special challenges of groundwater modelling for these areas. This book brings together the experience of internationally leading experts to fill a gap in the scientific and technical literature. It introduces state-of-the-art methods for modelling groundwater resources, illustrated with a wide-ranging set of illustrative examples from around the world. The book is valuable for researchers, practitioners in developed and developing countries, and graduate students in hydrology, hydrogeology, water resources management, environmental engineering and geography.

Download or read book Groundwater Quality Protection written by Stephen S. D. Foster and published by World Bank Publications. This book was released on 2002 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater is an essential natural resource for the economic and secure provision of drinking water supplies. Pollution hazard assessment is an essential part of environmental best practice for water supply utilities, both in terms of protecting groundwater quality from future pollution and mitigating threats posed by existing activities. This book looks at the need for groundwater protection strategies, and provides a technical guide to methodological approaches including: mapping aquifer pollution vulnerability; the delineation of groundwater supply protection areas; developing an inventory of subsurface contaminant load; and the assessment and control of groundwater pollution hazards. The guide is particularly relevant for the Latin American and Caribbean region where many cities are highly dependent upon groundwater resources.

Download or read book Landscape Ecology Function and Management written by J Ludwig and published by CSIRO PUBLISHING. This book was released on 1996-11-01 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book encapsulates the extensive knowledge developed by CSIRO's National Rangelands Program on how rangeland landscapes function and the implications for management. It looks at the ecology of rangeland landscape processes and deals with what happens when things go wrong, when a landscape loses its ability to efficiently capture and store water and nutrients - a state the authors call dysfunctional.Ways of managing rangelands in response to understanding landscape function are also considered. The concluding Section looks to the future providing some scenarios for the way rangeland landscapes may be used in 2020.

Download or read book Ecological Heterogeneity written by Jurek Kolasa and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: An attractive, promising, and frustrating feature of ecology is its complex ity, both conceptual and observational. Increasing acknowledgment of the importance of scale testifies to the shifting focus in large areas of ecology. In the rush to explore problems of scale, another general aspect of ecolog ical systems has been given less attention. This aspect, equally important, is heterogeneity. Its importance lies in the ubiquity of heterogeneity as a feature of ecological systems and in the number of questions it raises questions to which answers are not readily available. What is heterogeneity? Does it differ from complexity? What dimensions need be considered to evaluate heterogeneity ade quately? Can heterogeneity be measured at various scales? Is heterogeneity apart of organization of ecological systems? How does it change in time and space? What are the causes of heterogeneity and causes of its change? This volume attempts to answer these questions. It is devoted to iden tification of the meaning, range of applications, problems, and methodol ogy associated with the study of heterogeneity. The coverage is thus broad and rich, and the contributing authors have been encouraged to range widely in discussions and reflections. vi Preface The chapters are grouped into themes. The first group focuses on the conceptual foundations (Chapters 1-5). These papers exarnine the meaning of the term, historical developments, and relations to scale. The second theme is modeling population and interspecific interactions in hetero geneous environments (Chapters 6 and 7).

This book was released on 2013 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le bassin versant de l'Oued Amzaz, occupe une position mediane a l'interieur de l'Ouergha (Maroc). il s'etale sur une superficie de 38 720 hectars et il connait continuellement une erosion extreme. Cela est lie a l'interaction de plusieurs facteurs naturels tels que la quantite et l'agressivite des precipitations, la presence des pentes fortes, la densite faible du couvert vegetal et surtout la dominance des roches tendres. Le bassin versant de l'Oued Amzaz n'a pas echappe a l'intervention humaine qui rend le milieu tres vulnerable a l'erosion par le defrichement et la degradation du couvert vegetal et par des techniques agricoles souvent inadequates. La methode PAP/CAR a ete choisie afin d'etudier le phenomene dans sa globalite. Elle constitue un ensemble de directives emises par le PNUD pour la formulation d'un programme de lutte antierosives, base sur trois approches. La premiere approche consiste a realiser les differentes cartes thematiques et definir les facteurs preponderants de l'erosion. La deuxieme se penche sur la description des formes et des processus de l'erosion, et la derniere porte sur l'integration et la definition des degres du risque de l'erosion.
