  We study the transport properties of a relativistic fluid affected by chiral
and gauge-gravitational anomalies. The computation is performed in the
framework of the fluid/gravity correspondence for a 5 dim holographic model
with Chern-Simons terms in the action. We find new anomalous and non anomalous
transport coefficients, as well as new contributions to the existing ones
coming from the mixed gauge-gravitational anomaly. Consequences for the shear
waves dispersion relation are analyzed.
