Tue. May 24, 2022 10:45 AM - 12:15 PM Exhibition Hall Special Setting (2) (Exhibition Hall 8, Makuhari Messe)

convener:Yuki Kojima(Department of Civil Engineering, Gifu University), convener:Shoichiro Hamamoto(Department of Biological and Environmental Engineering, The University of Tokyo), Hirotaka Saito(Department of Ecoregion Science, Tokyo University of Agriculture and Technology), convener:Chihiro Kato(Faculty of Agriculture and Life Science, Hirosaki University), Chairperson:Yuki Kojima(Department of Civil Engineering, Gifu University), Shoichiro Hamamoto(Department of Biological and Environmental Engineering, The University of Tokyo), Hirotaka Saito(Department of Ecoregion Science, Tokyo University of Agriculture and Technology), Chihiro Kato(Faculty of Agriculture and Life Science, Hirosaki University)

This session covers the topics on fluid flow and mass transport in geological media. Subjects related to laboratory testing, subsurface characterization, theoretical analysis and numerical modeling will be discussed. Presentations on geo-pollution, remediation, geological disposal of hazardous wastes, mass transport in vadose zone, and environmental assessment from any fields, such as earth science, engineering, and agriculture, are welcome.
