Laboratory for Watershed Conservation Shinya HIRAMATSU Professor Hillslope stability Hydrologic properties in forest soil Landslides model Debris flow Sediment yield In Japan, sediment-related disasters occur frequently due to brisk sediment yield and sediment discharge. To prevent disasters affecting our lives and property, accurate prediction of such disasters is greatly needed. Therefore, for disaster prediction , it is necessary to understand and make clear mechanisms of sediment production and sediment yield , and all processes that affect slope stability , such as rainfall infiltration and runoff . In our laboratory, we conduct research on mechanisms of sediment-related disasters such as hillsides landslides and debris flow in mountainous areas, and rainfall-runoff processes, based on field measurements and experiments, from the viewpoint of disaster prevention and watershed conservation.

We manage the only herbarium in the Faculty of Agriculture where numerous taxonomic specimens are garnered.
