Box 100 A-1400 Vienna, Austria MANUAL ON MATHEMATICAL MODELS IN ISOTOPE HYDROGEOLOGY IAEA, VIENNA, 1996 IAEA-TECDOC-910 ISSN 1011-4289 © IAEA, 1996 Printed by the IAEA in Austria October 1996 FOREWORD Methodologies based on the use of naturally occurring isotopes are, at present, an integral part of studies being undertaken for water resources assessment and management. Applications of isotope methods aim at providing an improved understanding of the overall hydrological system as well as estimating physical parameters of the system related to flow dynamics. Quantitative evaluations based on the temporal and/or spatial distribution of different isotopic species in hydrological systems require conceptual mathematical formulations. Different types of model can be employed depending on the nature of the hydrological system under investigation, the amount and type of data available, and the required accuracy of the parameter to be estimated. Water resources assessment and management requires a multidisciplinary approach involving chemists, physicists, hydrologists and geologists. Existing model
