Based on the models of such as flow gravity similarity, flow resistance similarity, similarity of sediment incipient motion, similarity of sediment-carrying capacity, similarity of river-bed deformation, similarity of flow movement time, etc. , 4 flood discharge processes of Yongdinghe River are simulated for testing the effect of the flood process on the river-channel scour of the river, so as to determine the protection measures for the Inverted Siphon across Yongdinghe River.
