[A-GE46] Subsurface Mass Transport and Environmental Assessment

Mon. May 25, 2026 10:45 AM - 12:15 PM 104 (International Conference Hall, Makuhari Messe)

Chairperson:Yamaguchi Atsushi(Gifu University), Kojima Yuki(Department of Civil Engineering, Gifu University), Takahiro Tatsuno(Research faculty of Agriculture, Hokkaido University), Kato Chihiro(Faculty of Agriculture and Life Science, Hirosaki University), Tarolli Paolo(University of Padova)

This session covers the topic of fluid flow and mass transport in geological media consisting of soil or rock. 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 and energy transport in the vadose zone, and environmental assessment from any fields, such as earth science, engineering, and agriculture, are welcome.
