A hydrodynamic theory of both isotropic and hexatic flux liquids in high-{Tc} superconductors is presented. Weak microscopic pinning centers are described within the flux-flow model of Bardeen and Stephen, while strong macroscopic pinning centers set the boundary conditions for the flow. This model is relevant for understanding recent transport measurements by Worthington {ital et} {ital al}. in bulk Y-Ba-Cu-O single crystals. Flux-line entanglement leads to a large intrinsic viscosity, which increases at the isotropic-to-hexatic transition.
