Granular solid hydodynamics (GSH) is generalized to account for segregation. The necessary change is minimal, and consists in introducing the concentration c as an additional variable. There is no need for the stress and velocity of every population. GSH’s functionality with respect to all other granular phenomena – from elasto-plastic motion and shear band to the μ(I)-rheology – is preserved.
