In this study, the effect of visitations on resistance characteristics in open composite straight channel is investigated experimentally. Two kind of modeled vegetations are used. One is made of polyvinyl chloride and has permeability and the other is made of acryl plates and has no permeability. We conducted the experiments by varying setting location and width of the modeled vegetations. To set the modeled vegetations made of polyvinyl chloride on the flood plain makes the water depth deep. On the other hand, the water depth does not increase for the modeled vegetations made of the acryl plate. Location and width of the modeled vegetation does not affect the water depth or the resistance characteristic remarkably.
