Convener Shin-ichi Onodera  / Shinji Nakaya  / Seiko Yoshikawa  / Masahiro Kobayashi 
Scope We focus on hydrogeology and material transport in watersheds. We welcome these new topics in various fields. For example, heterogeneity and dynamics of groundwater flow system and material transport, scale up of material transport in soil to watershed, effect of human activity and climate change, N and P cycles, contaminant transport, river - groundwater interaction, new tracer methods etc.
