We present results for the elliptic and triangular flow coefficients v{sub 2} and v{sub 3} in Au+Au collisions at {radical}(s)=200 AGeV using event-by-event D=3+1 viscous hydrodynamic simulations. We study the effect of initial state fluctuations and finite viscosities on the flow coefficients v{sub 2} and v{sub 3} as functions of transverse momentum and pseudorapidity. Fluctuations are essential to reproduce the measured centrality dependence of elliptic flow. We argue that simultaneous measurements of v{sub 2} and v{sub 3} can determine {eta}/s more precisely.
