Tracers in Hydrology and Water Research is a comprehensive overview of the application of natural and artificial tracers in hydrology and environmental research. Taking a unique approach by providing the reader with a systematic and state of the art description of natural and artificial tracers, the book also covers key analytical techniques and applications, and modern tracer methods in the context of systematic hydrology. Tracers have become a primary tool for process investigation, qualitative and quantitative system analysis and integrated resource management. This book will outline the fundamentals of the subject, and examine the latest research findings, clearly showing the entire process of tracer application through the inclusion of numerous integrated case studies. As many techniques derive from different scientific disciplines (chemistry, biology, physics), the effort of compilation and integration into modern hydrology and environmental science research and application requires substantial continuity and experience, which certifies this group of authors. This book will be an invaluable reference not only for students and researchers within the field of Hydrology and Hydrogeology but also for engineers and other tracer techniques applying users.

Water is an essential element in maintaining life and is needed for all social and economic endeavours. It is impossible to overstate the importance of water in our daily lives. It is a vital element of nearly all aspects of human existence from sustenance, sanitation, and health, to basic human security. However, the increase in world population and rapid socio-economic development amongst other reasons impose high pressure on water resources around the world. Therefore, water security is a global concern today. Water for All: A Tribute to Prof. Dr. Ismail Abustan, presents an adaptive approach on various aspects on water and its management. In Malaysia’s context, this approach is very useful in trying to achieve and promote economic and social development without jeopardizing the sustainability of the ecosystem. This book highlights various studies and perspectives by a group of researchers on water and its management within the context of Integrated Water Resources Management (IWRM) that they have worked on with the late Prof. Dr. Ismail Abustan.
