  It is possible to formulate fluid dynamics in terms of group-valued
variables. This is particularly suited to the cases where the fluid has
nonabelian charges and is coupled to nonabelian gauge fields. We explore this
formulation further in this paper. An action for a fluid of relativistic
particles (with and without spin) is given in terms of the Lorentz and Poincare
(or de Sitter) groups. Considering the case of particles with flavor
symmetries, a general fluid action which also incorporates all flavor anomalies
is given. The chiral magnetic and chiral vorticity effects as well as the
consequences of the mixed gauge-gravity anomaly are discussed.
