This book was released on 2010 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies indicate that elevated nitrate accumulation has been occurring within the arid southwest, and this research focuses on investigating the occurrence of elevated soil nitrate in the mesic regions of northern Nevada, possible mechanics of nitrate accumulation and finally, remediation potential. Soil profiles in the Spanish Springs Valley, Nevada have indicated high concentration of nitrate 2-3 meters below the soil surface. The main vegetation of the area is sagebrush (Artemesia tridentata) and rabbitbrush (Chrysothamnus nauseosus) with groundwater depths varying from very deep (~ 28-30 m) to very shallow (~3 m). This research investigated the interaction of vegetative nitrate uptake, soil organic carbon, soil nitrate, and root growth with the elevated soil nitrate at these locations, as well as a possible nitrate accumulation mitigation technique, and the modeling of nitrate migration and microbial uptake within these locations. Soil and vegetative samples were collected from 4 different locations (three sites with deep groundwater and one with shallow groundwater), and previous data collected from monitor well installations were examined and analyzed. Laboratory experiments involving the migration and uptake of nitrate within carbon-augmented soil columns were conducted, and the modeling of these processes using Hydrus 1D was completed. The analyses indicate that the higher C:N in conjunction with shallow groundwater supports a higher root density with greater denitrification potential, precise irrigation of soil containing elevated nitrate layers can mitigate the transport of nitrate through microbial uptake, and Hydrus 1D modeling can, with accurate soil hydraulic properties, model the migration and uptake of nitrate within the soil columns. Also indicated from this research is the absence of distinction between sites in relation to the sagebrush (Artemesia tridentata) and rabbitbrush (Chrysothamnus nauseosus) plant leaf nitrate concentrations, as well as the capacity for microbial uptake from un-augmented soil. Conclusions indicate that nitrate levels in soil are directly influenced by groundwater levels which also appear to directly influence the C:N in the soil and the potential denitrification, and that soil within the Spanish springs Valley area contains sufficient carbon to promote the microbial uptake of almost half the nitrate contained within these elevated nitrate horizons when leaching may be initiated.

This book was released on 2004-01-09 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Water Science and Application Series, Volume 9. Groundwater recharge, the flux of water across the water table, is arguably the most difficult component of the hydrologic cycle to measure. In arid and semiarid regions the problem is exacerbated by extremely small recharge fluxes that are highly variable in space and time. --from the Preface Groundwater Recharge in a Desert Environment: The Southwestern United States speaks to these issues by presenting new interpretations and research after more than two decades of discipline-wide study.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers a broad and global level description of the current status of wastewater use in agriculture and then brings the readers to various places in the MENA Region and Europe to explain how some countries and regions have addressed the challenges during implementation. On a global scale, over 20 million hectares of agricultural land are irrigated using wastewater. This is one good, and perhaps the most prominent, example of the safe use potential of wastewater. Water scarcity and the cost of energy and fertilisers are among the main factors driving millions of farmers and other entrepreneurs to make use of wastewater. In order to address the technical, institutional, and policy challenges of safe water reuse, developing countries and countries in transition need clear institutional arrangements and more skilled human resources, with a sound understanding of the opportunities and potential risks of wastewater use. Stakeholders in wastewater irrigation who need to implement from scratch or improve current conditions, find it difficult to gather the necessary information on practical implementation aspects. The main objective of this book is to bridge that gap.

Download or read book Karst Hydrogeology and Geomorphology written by Derek Ford and published by John Wiley & Sons. This book was released on 2013-05-03 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1989, Karst Geomorphology and Hydrology became the leading textbook on karst studies. This new textbook has been substantially revised and updated. The first half of the book is a systematic presentation of the dissolution kinetics, chemical equilibria and physical flow laws relating to karst environments. It includes details of the many environmental factors that complicate their chemical evolution, with a critique of measurement of karst erosion rates. The second half of the book looks at the classification system for cave systems and the influence of climate and climatic change on karst development. The book ends with chapters on karst water resource management and a look at the important issues of environmental management, including environmental impact assessment, environmental rehabilitation, tourism impacts and conservation values. Practical application of karst studies are explained throughout the text. "This new edition strengthens the book's position as the essential reference in the field. Karst geoscientists will not dare to stray beyond arm's reach of this volume. It is certain to remain the professional standard for many decades." Journal of Cave and Karst Studies, August 2007
