The bottom image is from a shallow water simulation ( http://youtu.be/ifxFbez2u-U ), performed using Firedrake-Fluids ( http://www.geosci-model-dev-discuss.net/7/5699/2014/gmdd-7-5699-2014.html ). The rectangle represents the position of a tidal turbine.

This looks extremely nice! What are the simulations (bottom two plots)?
The sphere one is the nonlinear shallow water flow past a mountain test case (aka Williamson 5) [Williamson, D. L., Drake, J. B., Hack, J. J., Jakob, R., and Swarz- trauber, P. N.: A standard test set for numerical approximations to the shallow water equations in spherical geometry, J. Computat. Phys., 102, 211–224, 1992] I guess the bottom one is N-S flow past a rectangle?
