The development and practical implementation of isotope methodologies in water resources assessment and management have been proved to be useful. Isotope techniques can be applied to a wide spectrum of hydrological problems related to both surface and groundwater resources as well as environmental studies in hydro-ecological systems. The main aim of this book is to provide a review of basic theoretical concepts and principles of isotope hydrology methodologies and their practical applications to the researchers, field engineers, managers and academicians involved in research, development,...
