河床の力学的平衡状態に基づく樹林化回避地形の推定

抄録

In this study, we tried to estimate forestation avoidance topography from vertical agitation to horizontal agitation of riverbed based on dynamic equilibrium state of riverbed, and suggested effectiveness of the method. Discussions on forestation in previous studies have mainly focused on destruction mechanisms such as forest runoff in forested rivers. On the other hand, for two rivers of the forested river and the non-forested river, we extracted the feature quantity of the forestation topography and the forestation avoidance topography from the difference of vertical agitation and horizontal agitation of riverbed.
