Isotope hydrology 2011
Scope
The purpose of the session is to review the present state of knowledge of isotope hydrology, by bringing together hydrologists, geologists, volcanologists, geochemists and so on, to exchange current ideas and information. Papers, which are not based on isotopes for the present, are also welcome, if application of isotope techniques are scheduled in the future for the progress of the research.
