  We prove the existence and uniqueness of Stochastic Lagrangian Flows and
almost everywhere Stochastic Flows for non-degenearted SDEs with rough
coefficients. As an application of our main result, we show that there exists a
unique Stochastic Flow corresponding to each Leray-Hopf solution of 3D
Navier-Stokes equation in the DiPerna-Lions sense.
