How is sediment supply to watershed controlled through debris flow fan?

Insight from studies on the Ohya landslide

Abstract

The Ohya landslide in Shizuoka Prefecture is situated in the headwaters of the Abekawa watershed, contributing a significant amount of sediment to the watershed. Intensive studies on debris flows have been conducted in the Ohya landslide area due to the frequent occurrence of such events. This presentation focuses on discussing the connectivity of sediment discharge, drawing insights from the previous studies in the Ohya landslide.
