Numerical sedimentation simulation method based on natural provenance

The invention discloses a numerical sedimentation simulation method based on natural provenance, and belongs to the technical field of natural provenance simulation. The method comprises the steps ofconstructing an initial natural base according to geology and sedimentation background information of a natural provenance area to be studied, then simulating the sedimentation process of sediments ofthe initial natural base, obtaining the sedimentation thickness of the sediments in a sedimentation area, and taking the sedimentation area as a sedimentation base of the next moment, and repeating the last step till the simulation is finished to achieve the simulation of the natural provenance area to be studied. According to the method, by fully considering the hydrodynamic characteristics of the provenance area and the sedimentation area and adopting a hydrodynamic numerical simulation method to study the natural provenance, the simulation is closer to the actual sedimentation process; a computer is adopted for hyd
