Several researches established theory on stable channel cross-section of straight gravel rivers. Yamamoto (1994) showed the response of river width which was expanded artificially. However these are not able to explain the formation of distributaries at the alluvial fan and near river mouth. In this paper, the formation of distributaries is considered based on the stability of transverse river bed forms. The stability analysis which is used on bar formation process, is applied on this phenomenon. The results of this theory expressed the validity of the rational regime theory., application/pdf}, pages = {739--744}, title = {安定解析に基づく川幅の自律形成機構}, volume = {53}, year = {2009} }
