Sandy braided rivers can create extensive oil and gas reservoirs, with channel bars representing predominant sedimentary features. These bars, including compound middle channel bars and compound sidebars, exhibit complex internal architectural patterns resulting from multiple episodes of erosion, cutting, and redeposition during formation. To address these complexities, numerical simulations of sedimentation were employed to replicate the growth and evolution of the bars, enabling the analysis of repetitive sedimentation and erosion-cutting processes shaping their architecture. The results indicate the following:
