[H-GM04] Geomorphology

Mon. May 25, 2026 3:30 PM - 5:00 PM Exhibition Hall Special Setting (4) (Exhibition Hall 7&8, Makuhari Messe)

Chairperson:Hattanji Tsuyoshi(Institute of Life and Environmental Sciences, University of Tsukuba), Iwahashi Junko(GSI of Japan), Malatesta Claude Luca(GFZ Helmholtz Centre for Geosciences)

This session covers a wide range of themes in geomorphology, the study of landforms and Earth surface processes including slope, fluvial, coastal, glacial/periglacial processes and weathering especially in monsoonal, tectonically active landscapes. Applied topics such as geomorphological hazards and their mitigation as well as advances in geomorphological theory, techniques, modeling, field measurement, laboratory experiments, large-data analysis are also included.
