【Abstract】 The physical modeling is still a main approach to solve the sedimentation problems existing in the large stream training and hydraulic projects. In this paper, some key problems, usually found in the designing of physical model and conducting physical modeling, such as geometrical distortion, time distortion, and modeling of composition of bed load are discussed, and also the feasible solutions to them are proposed in this paper.更多还原
