This book presents a comprehensive guide on the applications of isotopic methods in hydrology. The book covers applications of water isotopes in freshwater spring hydrology, groundwater investigations in arid regions across desertic Rajasthan, and evolving spring rejuvenation studies across the Himalaya, including Nepal, Jammu, and Kashmir.

This book presents a comprehensive guide on the applications of isotopic methods in hydrology. It covers key isotopic techniques for tracing and analysing water in various hydrological systems. The inclusion of studies from different terrains, including mountainous, arid, coastal, and wetland regions, demonstrates the practical applications of these methods. The book covers applications of water isotopes in freshwater spring hydrology, groundwater investigations in arid regions across desertic Rajasthan, and evolving spring rejuvenation studies across the Himalaya, including Nepal, Jammu, and Kashmir. The book also includes methodology-focused chapters that discuss partitioning evapotranspiration using oxygen and hydrogen isotopes, highlighting key methodological challenges and practical insights. The volume also presents integrated numerical and isotope-based approaches for submarine groundwater discharge studies. It is designed for graduate students, researchers, and practitioners seeking to understand the role of isotopes in hydrology and water resource management.
