[A-HW22] Hydrological Cycle and Water Environment

Thu. May 24, 2018 3:30 PM - 5:00 PM 104 (1F International Conference Hall, Makuhari Messe)

convener:Seiya Nagao(Institute of Nature and Environmental Technology, Kanazawa University), Isao Machida(Geological Survey of Japan), Shin'ichi Iida(国立研究開発法人森林研究・整備機構森林総合研究所森林研究部門森林防災研究領域水保全研究室, 共同), Takeshi Hayashi(Faculty of Education and Human Studies, Akita University), Chairperson:Machida Isao(Geological Survey of Japan, AIST), Nagao Seiya(Institute of Nature and Environmental Technology, Kanazawa University), Hayashi Takeshi(Faculty of Education and Human Studies, Akita University), Iida Shin'ichi(Forestry and Forest Products Research Institute)

We focus on various issues of water cycle and environment and aim to answer questions of hydrological and earth system sciences including 1) surface, subsurface and evapotranspiration processes of water cycle; 2) natural and anthropogenic hydrothermal systems, 3) environments issues and studies on a watershed or global scale, 4) water-related issues with ecological, environmental, and geochemical aspects, and 5) other issues in hydrological sciences. This session welcomes presentations regarding various kinds of approaches and techniques such as field survey, remote sensing, isotope tracers, numerical simulation, and theoretical analysis.
