Available in PDF, EPUB and Kindle. Book excerpt: This Special Issue "Applications of Stable Isotopes and Tritium in Hydrology" addresses the current state-of-the-art applications of stable isotopes and tritium in studies of hydrological process and the whole water cycle. The six scientific papers belonging to this SI show a wide variety of isotope applications in various studies performed locally or regionally, but the conclusions obtained may be valid worldwide. Precipitation, groundwater, and surface waters belong to classical water bodies, while evapotranspiration, effects of farming, and drip water in karst caves seldom present applications of water isotopes.

Book excerpt: Within the discipline of environmental sciences, the stable-isotope methodology is being increasingly used, especially in the study of the water cycle and of paleo-climatology. This book reviews the natural variability of stable isotopes in the hydrosphere, describing the physico-chemical basis of isotope fractionalism, and applying this knowledge to natural waters as they move through the hydrologic cycle from the ocean to the atmosphere, the biosphere and the lithosphere. It focuses on the processes at the surface-atmosphere and land-biosphere-atmosphere interfaces, since these are the sites of major changes in isotope composition. In response to the increasing awareness of our changing climate, a discussion on the global view of the changing water cycle, in the past and future, concludes up the presentation.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook is intended to confirm the necessity of applying in: Fretwell's Law: by which, Stable isotope data may cause severe and contagious stomach upset if taken alone. To prevent upsetting reviewers' stomachs and your own, take stable isotope data with a healthy dose of other hydrologic, geologic, and geochemical information. Then, you will find stable isotope data very beneficial. The main reason that render the use of the treated isotopic data illegal, incomparable and have thus lost some of its power as an effective tool is in the ignorance of both time and space variation in treating isotopic data. Accordingly, for any quantitative application of the stable isotopes labeling of waters a geo-hydrological tool, it is necessary to establish how well the isotopic composition of a groundwater source is defined in a supposedly homogenous geographic setting. Both time and space variations were not considered in most of isotopic data of major aquifer system.

Download or read book Use of Water Stable Isotopes in Hydrological Process written by Polona Vreča and published by . This book was released on 2020-10-12 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stable and radioactive isotopes in water are powerful tools in the tracking of the path of water molecules through the whole water cycle. In the last decade, a considerable number of studies have been published on the use of water isotopes, and their number is ever-growing. The main reason is the development of new measurement techniques (i.e., laser absorption spectroscopy) that allow measurements of stable isotope ratios at ever-higher resolutions. Therefore, this compilation of papers has been published to address the current state-of-the-art water isotope methods, applications, and interpretations of hydrological processes, and to contribute to the rapidly growing repository of isotope data, which is important for future water resource management. We are pleased to present here a book with new findings in thirteen original research papers and one review paper issued in the Water MDPI Special Issue (SI) "Use of Water Isotopes in Hydrological Processes". The authors report the use of water isotopes in hydrological processes worldwide, including studies at both local and regional scales related to either precipitation dynamics or to different applications of water isotopes in combination with other hydrochemical parameters in investigations of surface water, snowmelt, soil water, groundwater and xylem water to identify the hydrological and geochemical processes.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers the distribution, hydrochemistry and geophysics of the naturally occurring stable isotopes namely: hydrogen, oxygen and radioactive tritium, carbon and other cosmogenic and radiogenic isotopes of the uranium-thorium series, in the oceans and in atmosphere, the earth's surface and ground water. The use of environmental isotopes in the three main areas of natural waters is discussed: origin, dynamics and residence time in natural reservoirs. The origin of the hydrosphere is examined in the light of isotopic, new cosmochemical and recent theoretical results. The book will be of interest to scientists and researchers who use environmental isotopes in solving scientific and practical problems in hydrology, hydrogeology, oceanography, meteorology, hydrogeochemistry and cosmochemistry. Lecturers, students and postgraduates in these fields will also find it useful.
Download or read book Applied Isotope Hydrogeology written by F.J. Pearson and published by Elsevier. This book was released on 1991-04-16 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1980, Nagra, the Swiss National Cooperative for the Storage of Radioactive Waste, began a comprehensive field investigation programme to assess the feasibility and safety of a repository for the final disposal of high-level radioactive waste in northern Switzerland. An international team of scientists has carried out a comprehensive study on the isotope hydrogeology of deep groundwaters. One of the major implications of this work pertains to the storage of radioactive waste. The study goes far beyond an in-depth regional study as it draws together the results of diverse techniques, many of which have been re-evaluated or further developed.This book presents in great detail the results of one of the most comprehensive isotope hydrology studies ever undertaken.

This book was released on 1999 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous hydrological projects have been carried out using isotopic methods over the last two decades in the ESCWA region, which includes the Arabian Peninsula, the Arabian countries to the north, and Egypt. The large amount of data obtained from groundwater samples has been evaluated together with the hydrogeological, hydrochemical and water management data available for the area. Analyses of the stable isotopes of oxygen, hydrogen, and carbon in the groundwater samples, as well as the naturally occurring radioactive isotopes of hydrogen and carbon are used for the localization of groundwater recharge areas; determination and quantification of mixtures of groundwater from different sources; reconstruction of groundwater flow systems on regional and local scales; determination of the paleoclimatic effects on the geohydraulic conditions; determination of groundwater ages, i.e., residence times; and distinguishing between renewable and fossil groundwater resources. Extensive hydrological studies using isotopic methods have been conducted in the ESCWA region on the following aquifer systems and topics: isotopic composition of precipitation in Jordan and Syria; groundwater turnover in karst aquifers in the highlands of western Jordan, the mountains in western Syria and the West Bank; groundwater recharge from precipitation and surface water on the Damascus plain; origin and age of groundwater in the basalt aquifer system in Jordan and Syria; recently recharged freshwater lenses and fossil groundwater in Badiye and Hamad (steppe and desert regions in Syria and eastern Jordan and the adjacent areas in Iraq and Saudi Arabia); low of fossil groundwater and local, recently recharged groundwater in Paleogene carbonate aquifers in eastern Saudi Arabia, the Golf region, and southern Oman; groundwater recharge from flash floods in the aquifers in unconsolidated rock in wadis and coastal plains of the Arabian Peninsula; age and origin of groundwater in aquifers in consolidated rock in the mountains of Oman. The discussion of the hydrogeological significance of isotope data is supplemented by comments on the most important current hydrogeological problems in the ESCWA region that could be investigated using isotopic methods. These include problems of groundwater recharge, the provenance of groundwater, groundwater flow systems on regional and local scales, paleohydrological conditions, and groundwater quality, particularly contamination by human activities. All available publications on the isotope hydrology of the ESCWA region are listed in the bibliography, as well as basic publications on isotope hydrology in arid regions.
