Although many studies discussed channnel initiation based on models or field observations, analysis filling th gap between models and observations is required for the better understanding of channnel initiation mechanism. Many reserchers focused on the conditions of shallow landsliding in humid forested mountains, while few studies discussed the role of bedload transport　bellow channnel heads. The aim of the present study is to analuze the thresholds for channel initiaion by bedload transport based on the hydro-geomorphic observation in channnel heads. The investigated area is located in the eastern Ashio Moutains, eastern Japan (Awano Town, Tochigi Prefecture).
