This paper computes the conservation laws of the Rosenau-KdV-RLW equation with power law nonlinearity by the aid of multiplier approach in Lie symmetry analysis. This equation models the dynamics of dispersive shallow water waves along lake shores and beaches. The usual conservation laws are reported earlier that are computed from basic mathematical principles. The conservation laws in this paper are extracted using Lie symmetry analysis. The corresponding conserved quantities are computed from their respective densities.
