[A-HW27_1AM1] Hydrological Cycle and Water Environment

Thu. May 1, 2014 9:00 AM - 10:45 AM 424 (4F)

Convener:*Takeshi Hayashi(Faculty of Education and Human Studies, Akita University), Youhei Uchida(Geological Survey of Japan, AIST), Atsushi Higuchi(Center for Environmental Remote Sensing (CEReS), Chiba University, Japan), Seiya Nagao(Institute of Nature and Environmental Technology, Kanazawa University), Chair:Takeshi Hayashi(Faculty of Education and Human Studies, Akita University), Youhei Uchida(Geological Survey of Japan, AIST), Atsushi Higuchi(Center for Environmental Remote Sensing (CEReS), Chiba University, Japan), Seiya Nagao(Institute of Nature and Environmental Technology, Kanazawa University)

We discuss on hydrological cycle and water environment in various scales in views of earth sciences. This session involves issues such as hydrological processes in surface and subsurface water including evapotranspiration, natural and anthropogenic hydrothermal system, issues in environmental studies in watershed or global scale, issues of water related with ecological environment or geochemical aspects, and other issues in hydrological sciences.
