N2 - The Weakly-Compressible Moving Particle Semi-implicit (WC-MPS) approach is applied to investigate the wave propagation and the flow fields induced by sliding blocks. Since there are already studies focusing on an inclination slope of 45°, two slope angles, 40° and 50°, are used to obtain the additional experimental results. Sliding blocks are released under water, where the top edges are parallel to the water surface. The simulation results are compared to the experimental measurements both on the water surface and the velocity distribution at specific locations. To analyze the flow fields, contour and vector plots illustrate the flow characteristics for the entire velocity distribution in the simulation domain along with the vortex movements from the sliding block. Two case scenarios are presented to investigate the velocity distribution of the sliding block. For the first case scenario, seven cross-sections, including the front edge, the top edge, and the back edge of the sliding block were selected to further identify the characteristics of the horizontal and vertical velocity distributions. The second case scenario has five specific locations at the front, top and back edge of the block. A good agreement was obtained between the WC-MPS simulated results to the experimental data.
