The Resilience Research Center in Hiroshima University (HRRC) has launched a new project, named "Gagara-Yama Demonstration Experiment of Sediment-related Disasters," aimed at elucidating the mechanism behind slope failures and debris flows to protect lives from sediment-related dis-asters. The Gagara-Yama mountain, located inside the HU campus, is composed of weathered granite, which is at risk of collapsing during heavy rainfall.

Measurement equipment for groundwater level, water pres-sure, and temperature have been installed in the area. A satellite positioning, navigation, and timing system will be set up to collect basic data, such as changes in the ground-surface topography. We welcome research collaborators and appreciate all the support from abroad for our unique activities.
