We investigate the correlation between various aspects of the initialgeometry of heavy ion collisions at the Relativistic Heavy Ion Colliderenergies and the final anisotropic flow, using v-USPhydro, a 2+1 event-by-eventviscous relativistic hydrodynamical model. We test the extent of which shearand bulk viscosity affect the prediction of the final flow harmonics, $v_n$,from the initial eccentricities, $\varepsilon_n$. We investigate in detail theflow harmonics $v_1$ through $v_5$ where we find that $v_1$, $v_4$, and $v_5$are dependent on more complicated aspects of the initial geometry that areespecially important for the description of peripheral collisions, including anon-linear dependence on eccentricities as well as a dependence onshorter-scale features of the initial density. Furthermore, we compare ourresults to previous results from NeXSPheRIO, a 3+1 relativistic idealhydrodynamical model that has a non-zero initial flow contribution, and findthat the combined contribution from 3+1 dynamics and non-zero, fluctuatinginitial flow decreases the predictive ability of the initial eccentricities, inparticular for very peripheral collisions, but also disproportionately incentral collisions.
