[A-HW19] Hydrology & Water Environment

Wed. May 24, 2023 9:00 AM - 10:15 AM 105 (International Conference Hall, Makuhari Messe)

convener:Koichi Sakakibara(Department of Environmental Sciences, Faculty of Science, Shinshu University), Sho Iwagami(Forestry and Forest Products Research Institute, Forest Research and Management Organization, National Research and Development Agency), Takeshi Hayashi(Faculty of Education and Human Studies, Akita University), Keisuke Fukushi(Institute of Nature & Environmental Technology, Kanazawa University), Chairperson:Koichi Sakakibara(Department of Environmental Sciences, Faculty of Science, Shinshu University), Shin'ichi Iida(Department of Disaster Prevention, Meteorology and Hydrology, Forestry and Forest Products Research Institute), Sho Iwagami(Forestry and Forest Products Research Institute, Forest Research and Management Organization, National Research and Development Agency), Takeshi Hayashi(Faculty of Education and Human Studies, Akita University), Keisuke Fukushi(Institute of Nature & Environmental Technology, Kanazawa University)

We focus on various issues of water cycle and environment and aim to answer questions of hydrological and earth system sciences; 1) surface, subsurface and their boundary hydrological 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. We welcome presentations regarding various kinds of approaches and techniques such as field survey, remote sensing, chemical and isotope tracers, numerical simulation, and theoretical analysis. This session is jointly hosted by societies of water-related geoscience (Geochemical Society of Japan, Japanese Association of Groundwater Hydrology, Japanese Association of Hydrological Sciences, and Japan Society of Hydrology and Water Resources), and accepts wide-range research topics related to water cycle and environment described above.
