[H-CG37_30PM1] Interdisciplinary approach to earth's changing surface

Wed. Apr 30, 2014 2:15 PM - 4:00 PM 421 (4F)

Convener:*Naofumi Yamaguchi(Center for Water Environment Studies, Ibaraki University), Hajime Naruse(Department of Geology and Mineralogy, Graduate School of Science, Kyoto University), Shigehiro Fujino(Faculty of Life and Environmental Sciences, University of Tsukuba), Koji Seike(Atmosphere and Ocean Research Institute, University of Tokyo), Chair:Shigehiro Fujino(Faculty of Life and Environmental Sciences, University of Tsukuba)

To understand landscape evolution and dynamics of erosion, transport and sedimentation of earth-surface materials, the latest results of multiple research fields including engineering and earth sciences will be presented. As well as any researches of sedimentology and sedimentary petrology, interaction between fluid, sediments and geomorphology is focused. Interdisciplinary discussions of science, disaster prevention and resource exploration will be expected.
