Abstract: We construct the conservation laws for a variable coefficient variant Boussinesq system, which is a third‐order system of two partial differential equations. This system does not have a Lagrangian and so we transform it to a system of fourth‐order, which admits a Lagrangian. Noether’s approach is then utilized to obtain the conservation laws. Lastly, the conservation laws are presented in terms of the original variables. Infinite numbers of both local and nonlocal conserved quantities are derived for the underlying system.
