[A-HW25_2AM2] Isotope Hydrology 2014

Fri. May 2, 2014 11:00 AM - 12:45 PM 414 (4F)

Convener:*Masaya Yasuhara(Geological Survey of Japan, AIST), Kohei Kazahaya(Geological Survey of Japan, AIST), Shinji Ohsawa(Institute for Geothermal Sciences, Graduate School of Science, Kyoto University), Masaaki Takahashi(Geological Survey of Japan (GSJ), National Institute of Advanced Industrial Science and Technology (AIST)), YUICHI SUZUKI(Faculty of Geo-Environmental Sience,Rissho University), Futaba Kazama(Social Cystem Engineering, Division of Engineering, Interdiciplinary Graduate School of Medical and Engineering, University of Yamanashi), Kazuyoshi Asai(Geo Science Laboratory), Chair:Kazuyoshi Asai(Geo Science Laboratory), Kazuhiro Amita(Department of Earth Science & Technology Faculty of Engineering and Resource Science Akita University)

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.
