Based on the analysis of the water and sediment characteristics of the Maliuzhou Waterway, this paper establishes a local physical model near the project and a mathematical model of two-dimensional tidal sediment with reasonable hydro-logical and sediment parameters of river scouring so as to simulate the river scouring under the extreme conditions of the Maliuzhou Waterway. Based on the calculation results, this paper divides the fracture surface and longitudinal section of the river near the project and analyzes its fracture surface, section and channel layout so as to explore the characteristics of the river scouring under the extreme conditions of the Maliuzhou Waterway. This study shows that under extreme conditions, the deepest scouring of the Maliuzhou Waterway is in the main channel, and the hydrodynamic axis and the talweg of the river channel show little change.
