The system is an extension of the well known shallow-water system to the situation where the waves are long, but not so long that dispersive effects can be neglected.\n  In the current work, the focus is on deriving mass, momentum and energy densities and fluxes associated with the Serre-Green-Naghdi system. These quantities arise from imposing balance equations of the same asymptotic order as the evolution equations.
