Abstract

This paper deals with hydraulic characteristics of two lane flow in a steep channel composed of large bed materials. After the recognition of the regime, field investigation and also numerical experiment were made in the case of kinu-river. As results of the study, the regime of this meandering system was found to be one of the stable condition of meandering system and also discussed about the disturbing factors.
