Landslide-generated　wave　(LGW)　events　are　particularly　dangerous　as　they　are　associated　with　a　high　risk　of　loss　of　life　and　severe　economic　damage.　The　lifecycle　of　a　LGW　can　be　decomposed　into　various　distinct　stages,　such　as　generation　and　propagation.　The　modeling　of　the　entire　LGW　lifecycle　through　the　use　of　a　single　model　is　difficult　as　the　hazard　characteristics　of　LGWs　differ　widely　across　spatial　and　temporal　scales.　Therefore,　this　study　proposed　a　Hybrid　Smoothed　Particle　Hydrodynamics　(SPH)　-　Boussinesq　model　to　overcome　the　limitations　of　individual　models　and　to　acquire　a　more　reliable　method　of　analyzing　LGWs.　An　SPH　two-layer　depth-integrated　model　was　combined　with　a　Boussinesq　model　(FUNWAVE)　through　the　implementation　of　a　transformation　zone.　The　proposed　hybrid　model　was　then　applied　within　the　evaluation　of　the　potential　risk　for　the　generation　of　LGWs　by　impulsive　waves　generated　by　the　Halaowo　Landslide　in　Jinsha　River,　China.　This　study　provides　a　discussion　of　the　process　for　predicting　waves　and　generated　a　risk　map　according　to　the　reference　emergency　response　plan.　©　2021　Elsevier　Ltd
