Abstract: In order to deeply study the development process and sedimentary model of the distal shallow-water braided river delta, based on the modern sedimentary hydrodynamic conditions, the initial model and boundary conditions of the hydrodynamic depositional numerical simulation were designed. The sedimentary process of the distal shallow-water braided river delta was numerically simulated. The characteristics of the sedimentary thickness and flow velocity were analyzed. The results of the hydrodynamic depositional numerical simulation and the modern sedimentary examples were compared and analyzed. The controlling effect of distributary channels of different levels on the proliferation of shallow-water braided river delta. The sedimentary model based on the classification of distributary channel were summarized. The results show that: 1) in a complete flood-interflood
