[A-HW27] Water and material transport and cycle in watersheds: from headwater to coastal area

Sun. May 24, 2015 4:15 PM - 6:00 PM 301B (3F)

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

We focus on water and material transport and cycle in watersheds. 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 watershed 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, and sediment analysis etc.
