[A-HW16] Water and material transport and cycles in catchment ecosystems: from headwater to coastal area

Thu. May 26, 2016 1:45 PM - 3:15 PM 302 (3F)

Convener:*Seiko Yoshikawa(Narional Institute for Agro-Environmental Sciences), Masahiro Kobayashi(Forestry and Forest Products Research Institute), Noboru Okuda(Research Institute for Humanity and Nature), Shin-ichi Onodera(Graduate School of Integrated and Arts Sciences, Hiroshima University), Kazuhisa Chikita(Department of Earth and Planetary Sciences, Faculty of Science, Hokkaido University), Tomohisa Irino(Faculty of Environmental Earth Science, Hokkaido University), Shinji Nakaya(Department of Water Environment and Civil Engineering, Faculty of Engineering, Shinshu University), Mitsuyo Saito(Graduate School of Environmental and Life Science, Okayama University), Chair:Noboru Okuda(Research Institute for Humanity and Nature), Tomohisa Irino(Faculty of Environmental Earth Science, Hokkaido University)

We focus on water and material transport and cycle in catchment ecosystems. The area includes headwater to coastal or estuarine area. We welcome these new topics in various scales and fields. For example, material transport in soil, slope and catchment scale, suspended material transport interacting with dissolved material, groundwater flow system and material transport, heterogeneity and dynamics, scale up from soil to watershed, effect of human activity and climate change for long period, N and P cycles, contaminant transport from watershed to coastal and ocean areas and its effect, river - groundwater interaction, new tracer methods, catchment ecosystems, and sediment analysis etc.
