- Flow Characteristics in Channel with Vegetation
抄録
It is very important in river management works to take into account the influences of the vegetation to the flow during the flood. Logarithmic or parabolic law can be a good assumption for the vertical profile of downstream velocity distribution in open channel flow without vegetation. However, these assumptions cannot be applied to the flow through the vegetation because of the strong effect of the resistance caused by trees.<BR>In this paper, the vertical distribution of flow through the vegetation is predicted theoretically. The bed drag coefficient has to be changed in order to calculate the depth averaged downstream velocity accurately.
