Download or read book Water Management in New Zealand s Canterbury Region written by Bryan R. Jenkins and published by Springer. This book was released on 2018-01-06 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is designed to achieve two major purposes. The first is to describe the developments in water management policy in the Canterbury Region of New Zealand. The strategic approach, the collaborative engagement, and, the nested adaptive systems approach represent a paradigm shift in water management in New Zealand. The second is to delineate the sustainability framework that underpins the Canterbury approach. The framework is based on the concept of developing sustainability strategies to address critical failure pathways. While the focus of the book is on Canterbury, comparative applications of the framework to issues in other parts of New Zealand and international issues are proposed. The book can be used in at least two ways. The first is the application of a sustainability framework to the management of water in Canterbury region. The second is the exposition of a sustainability framework that can be applied to the management of water in a region with the application to Canterbury as an illustrative case study.

Download or read book A Structural Framework for Understanding the Spatial Distribution and Geochemical Variation of Natural Gas and Salt rich Groundwater in Shallow Aquifers of South central New York written by Rebecca Kreuzer and published by . This book was released on 2017 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This study examines the baseline water chemistry, evidence of fluid migration, and geo- structural patterns of methane and diluted brine components in 72 shallow groundwater wells and one "bore hole" brine sample from south-central NY. We hypothesize that fluid migration along faults, likely during Paleozoic tectonism, is the primary control on the spatial distribution and chemical variation of naturally migrated, exogenous hydrocarbon-brines in shallow Upper Devonian aquifers. To test this hypothesis we analyze groundwater samples from five south-central NY counties for a suite of geochemical tracers, including molecular and isotopic hydrocarbon, noble gas, and inorganic water chemistry, and apply numerical diffusion and Rayleigh solubility fractionation models to evaluate migration mechanisms. Sample locations are intentionally targeted for collection based on their association with a previously documented fault system. Our results indicate that there are significant correlations between the fault association of a groundwater well and the presence of migrated hydrocarbon-brines. Fault associated (FA) groundwater contains elevated radiogenic [4He], thermogenic [CH4], exogenous [20Ne], [Ba], and [Cl] first order indications of a thermogenic hydrocarbon-brine. In addition, fractionated hydrocarbon (i.e., elevated C1/C2 and decreasing ?13C-C1), crustal (i.e., 4He/CH4 > NY production gases) and atmospheric (i.e., elevated 20Ne/36Ar) gas ratios in methane- and salt- rich FA samples suggests an initial source, with a composition similar to the area's production gases, has undergone varying degrees of post-genetic alteration that likely occurred during a long-range, paired advective migration of hydrocarbon gases plus brines into overlying strata. We also identify differences in groundwater chemistry that relate to the type of fault association (e.g., thrust-FA vs. tear-FA); relative to thrust-FA samples, tear-FA samples have higher concentrations of thermogenic methane, radiogenic helium, and dissolved salts, as well as a distinctly higher Br/Cl and 4He/Ba. In addition, tear-FA samples show greater solubility-related fractionation of gas ratios (e.g., elevated 20Ne/36Ar and 4He/CH4), but less diffusion related mass fractionation (e.g., lower ?13C-C1). These results suggest tear faults and thrust faults have derived fluids from different stratigraphic horizons; specifically, tear-FA samples a chemical signature more consistent with a Marcellus source, while thrust-FA fluids are more likely to be sourced from the Upper Devonian. In turn, this suggests that there is a secondary detachment horizon in Upper Devonian strata; while the tear-faults sole into and derive fluids from the primary decollement (i.e., the Salina/Marcellus), the thrust faults sole into and derive fluids from the overlying Upper Devonian detachment. Through consideration of the tectonic, geological, and structural framework of the region, we suggest that geochemical evidence of fluid migration in shallow groundwater can be used to identify and geometrically constrain previously undocumented fault systems."--Pages viii-ix.

This book was released on 2018-11-28 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is an outcome of the collaboration between the Soil and Water Management & Crop Nutrition Section, Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, Department of Nuclear Sciences and Applications, International Atomic Energy Agency (IAEA), Vienna, Austria, and Dr. Shabbir A Shahid, Senior Salinity Management Expert, Freelancer based in United Arab Emirates.The objective of this book is to develop protocols for salinity and sodicity assessment and develop mitigation and adaptation measures to use saline and sodic soils sustainably. The focus is on important issues related to salinity and sodicity and to describe these in an easy and user friendly way. The information has been compiled from the latest published literature and from the authors’ publications specific to the subject matter. The book consists of six chapters. Chapter 1 introduces the terms salinity and sodicity and describes various salinity classification systems commonly used around the world. Chapter 2 reviews global distribution of salinization and socioeconomic aspects related to salinity and crop production. Chapters 3 covers comprehensively salinity and sodicity adaptation and mitigation options including physical, chemical, hydrological and biological methods. Chapter 4 discusses the efforts that have been made to demonstrate the development of soil salinity zones under different irrigation systems. Chapter 5 discusses the quality of irrigation water, boron toxicity and relative tolerance to boron, the effects of chlorides on crops. Chapter 6 introduces the role of nuclear techniques in saline agriculture.

Download or read book Climate Change and Water written by Intergovernmental Panel on Climate Change / Working Group Technical Support Unit and published by . This book was released on 2008 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Technical Paper addresses the issue of freshwater. Sealevel rise is dealt with only insofar as it can lead to impacts on freshwater in coastal areas and beyond. Climate, freshwater, biophysical and socio-economic systems are interconnected in complex ways. Hence, a change in any one of these can induce a change in any other. Freshwater-related issues are critical in determining key regional and sectoral vulnerabilities. Therefore, the relationship between climate change and freshwater resources is of primary concern to human society and also has implications for all living species. -- page vii.
