[A-HW18] Isotope Hydrology 2016

Wed. May 25, 2016 10:45 AM - 12:15 PM 202 (2F)

Convener:*Masaya Yasuhara(Rissho Univ.), Kohei Kazahaya(Geological Survey of Japan, AIST), Kazuyoshi Asai(Geo Science Laboratory), Shinji Ohsawa(Institute for Geothermal Sciences, Graduate School of Science, Kyoto University), Futaba Kazama(Social Cystem Engineering, Division of Engineering, Interdiciplinary Graduate School of Medical and Engineering, University of Yamanashi), Masaaki Takahashi(The National Institute of Advanced Industrial Science and Technology), YUICHI SUZUKI(Faculty of Geo-Environmental Sience,Rissho University), Chair:Takashi Nakamura(International Research Center for River Basin Environment, University of YAMANASHI)

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.
