AR-based Dynamic Sandbox for Hydraulic Earth-rock Dam Break

VRiAR-based hydraulic scenes holds significant value for geological disaster display. However, the river dynamics and dam break models prevalent in computational fluid dynamics (CFD) and hydraulics rely largely on pure numerical simulations, lacking intuitive visual representation. In contrast, current AR-based physical simulation methods often fail to incorporate hydraulic parameters adequately, falling short of the accuracy needed for real hydraulic models. To bridge this gap, this paper proposes integrating a precise numerical river dynamics model into a visual fluid-solid interaction simulation framework, which achieves a balance between a realistic visual simulation of dam breaks and the numerical accuracy aligned with river dynamics models, while maintaining high computational efficiency.
