Abstract An incompressible‐smoothed particle hydrodynamics (I‐SPH) formulation is presented to simulate impulsive waves generated by landslides. The governing equations, Navier–Stokes are solved in a Lagrangian form using two‐step fractional method. Landslides this paper simulated submerged mass sliding along an inclined plane. During sliding, both rigid and deformable landslides considered. present numerical method examined for wedge into water In addition solitary wave heavy box falling inside water, known as Scott Russell generator, which example simulating rock avalanche artificial natural reservoirs, compared with experimental results. model also validated gravel approximately behaves like non‐Newtonian fluid. A rheological model, implemented combination of the Bingham general Cross models, utilized simulation landslide behaviour. order match data computed profiles landslides, parameters adjusted results effectively prove efficiency applicability I‐SPH these kinds complex free surface problems.
