流れの横断・平面特性を指標とした 持続可能な樹木管理方策に関する検討

抄録

In this study, to clarify the possible sustainability of vegetation management, we focus on the crossing and plane characteristics of flow by setting relative water depth and sinuosity as the new management indexes. Through the arrangement of crossing and plane characteristics and vegetation in the real river, the validity of new indexes is verified. And the influence to flow and river bed variation under relative water depth is confirmed by simulation which is numerical simulation of 2-D river bed transport model.

Based on the above analysis, the measure about vegetation management considered crossing and plane characteristics of flow is investigated. The effectiveness, efficiency and implementation of the measure has also been investigated.
