•Current models integrate hydrodynamic pressure and debris impacts.•LWD impacts vary with flow velocity and span length.•LWD impact increase the risk of deck-unseating. During extreme flooding events, bridges could experience large lateral displacements or even collapse due to either strong hydrauli...
