Submarine landslides are inherently difficult to detect, complicating the timely issuance of disaster warnings and rapid risk assessments. Understanding catastrophic evolution submarine under complex environmental conditions is fundamental marine landslide prevention mitigation. This study employs a simulation approach at model test scale, leveraging secondary development open-source programs, investigate multi-condition processes underwater gradually varying wave conditions. The research elucidates how different slope material types influence flow velocity changes on surface. It also examines impact loads toe baffle during sliding process, identifying density (ρ), viscosity (η), fluidity index (n) as primary parameters controlling movement energy process. Furthermore, reproduces in multi-stage environments, revealing progressive behavior staged accumulation characteristics double-slope surfaces. These findings provide valuable insights for safety protection reduction design nearshore landslides.
