  We obtain the constitutive relations for the stress tensor and gauge current
in $(1+1)$ dimensional hydrodynamics in the presence of both gauge and
gravitational (conformal as well as diffeomorphism) anomalies. The relations
between response parameters and anomaly coefficients are also found. The role
of the Israel-Hartle-Hawking vacuum is emphasized. Finally, in the absence of
gauge fields, earlier results obtained by a hydrodynamic expansion are
reproduced.
