  The lecture notes cover the emergence of generalized hydrodynamics for the
classical and quantum Toda chain, the classical Calogero fluid, the
Ablowitz-Ladik discretization of the non-linear Schroedinger equation, and the
Lieb-Liniger delta-Bose gas. Such diverse models have structurally identical
hydrodynamic equations. Added is a comparison with conventional soliton gases.
