Quantum impurity models (QIMs) are ubiquitous throughout physics. Assimplified toy models they provide crucial insights for understanding morecomplicated strongly correlated systems, while in their own right are accuratedescriptions of many experimental platforms. In equilibrium, their physics iswell understood and have proven a testing ground for many powerful theoreticaltools, both numerical and analytical, in use today. Their non-equilibriumphysics is much less studied and understood. However, the recent advancementsin non equilibrium integrable quantum systems through the development ofgeneralized hydrodynamics (GHD) coupled with the fact that many archetypal QIMsare in fact integrable presents an enticing opportunity to enhance ourunderstanding of these systems. We take a step towards this by expanding theframework of GHD to incorporate integrable interacting QIMs. We present a setof Bethe-Boltzmann type equations which incorporate the effects of impurityscattering and discuss the new aspects which include entropy production. Theseimpurity GHD equations are then used to study a bipartioning quench wherein arelevant backscattering impurity is included at the location of thebipartition. The density and current profiles are studied as a function of theimpurity strength and expressions for the entanglement entropy and fullcounting statistics are derived.
