Experiments and Numerical Calculations of Fluid Forces on Slope Protection Blocks of River Embankments in Subcritical and Supercritical Flow Conditions

Key Points

• The study aims to verify the effectiveness and accuracy of numerical calculations in assessing fluid forces on slope protection blocks.
• Conducted hydraulic model experiments and numerical calculations.
• Compared fluid forces on individual blocks in uniform and jet flow conditions.
• Applied a three-dimensional parallel computing method based on the multiphase flow theory (MICS).
• Numerical calculations aligned closely with hydraulic model experimental results for free water surfaces.
• Confirmed the validity of the three-dimensional computing method for determining hydraulics properties of single blocks.
