Abstract: The integration of deposition physical simulation and numerical simulation is an inevitable trend in the development of deposition simulation technology. Taking the shoal water delta as an example, the author explores the feasibility of integrating deposition physical simulation and numerical simulation. Three variables, namely sediment ratio, lake level change, and inlet discharge, were selected to simulate shoal water deltas using deposition physical and numerical simulation methods. Quantitative analysis was conducted using indicators such as the length-width ratio, area, and shoreline roughness. The analysis results indicate that there are differences in details between the physical simulation and numerical simulation of deposition in shoal water deltas, but they are consistent in macroscopic changes. And the similarity between the two simulation results is relatively high. This study is of great significance for the integrated exploration of deposition physical simulation and deposition numerical simulation.
