First I shall present a geometrical/topological theory of the structure and its transitions of 2D incompressible flows. This includes in particular a). structural and block stabilities, and b). structural bifurcation and boundary layer separations of 2D incompressible flows.

Then I shall discuss two applications. The first application is on the characterization and numerical simulation of boundary layer separations in driven cavity flows. The second application is on wind driven ocean circulation.
