  We study the transport properties of long quantum wires by generalizing the
Luttinger liquid approach to allow for the finite lifetime of the bosonic
excitations. Our theory accounts for long-range disorder and strong electron
interactions, both of which are common features of experiments with quantum
wires. We obtain the electrical and thermal resistances and thermoelectric
properties of such quantum wires. We cast our results in terms of the thermal
conductivity and bulk viscosity of the electron liquid and give the temperature
scale above which the transport can be described by classical hydrodynamics.
