Practical Isotope Hydrology

In Indian context.

Isotope hydrology is a field of hydrology which is concerned with the utilization of isotope dating to estimate the age and origins of water. It also studies the movement of water within the hydrologic cycle. Water consists of water molecules carrying unique fingerprints located in part on different proportions of oxygen and hydrogen isotopes. Isotope hydrology helps in creating an elaborated picture of earth's water resources. It is primarily involved in using stable isotopes to determine the age of ice or snow. Its techniques are also used for conserving water supplies, controlling pollution and mapping aquifers. This book outlines the processes and applications of isotope hydrology in detail. It will also provide interesting topics for research which interested readers can take up. Those in search of information to further their knowledge will be greatly assisted by this book.

"Isotope Tracers in Catchment Hydrology" is the first synthesis of physical hydrology and isotope geochemistry with a catchment focus, and is a valuable reference for professionals and students alike in the fields of hydrology, hydrochemistry, and environmental science.

Environmental isotope and nuclear techniques provide unmatched insights into the processes governing the water cycle and its variability. This monograph presents state of the art applications and new developments of isotopes in hydrology, environmental disciplines and climate change studies. Coverage ranges from the assessment of groundwater resources in terms of recharge and flow regime to studies of the past and present global environmental and climate changes.

Groundwater is an increasingly important resource to human populations around the world, and the study and protection of groundwater is an essential part of hydrogeology - the subset of hydrology that concentrates on the subsurface. Environmental isotopes, naturally occurring nuclides in water and solutes, have become fundamental tools for tracing

The Handbook of Environmental Isotope Geochemistry comprises a series of books, each focussing on a selected environment, presenting in-depth reviews of all relevant studies and results obtained in specific research areas. Theoretical aspects as well as practical applications of isotope techniques are treated and extensive bibliographies are included. The handbook will cover the terrestrial, marine, and high temperature environments, and all will undoubtedly be welcomed by geologists, geochemists, hydrologists, climatologists and soil scientists. The complete Handbook will thus provide a valuable overview of the whole field of environmental isotope geochemistry, and will be suitable for graduate level instruction in isotope geology. Individual volumes will also be a valuable aid to study in hydrogeology, oceanography, economic geology, Quaternary geology and igneous metamorphic petrology.
