===Flows over 3D and 2D Hills===
==Sample Data Plots==


The plots below show profiles of the mean \(U\) velocity, rms velocities and Reynolds shear stress
at three locations along the flat plate.

The plots below show profiles of the mean \(U\) velocity, rms \(u'\) velocity and Reynolds shear stress
at selected streamwise locations in the axisymmetric hill and 2D ridge cases.

The plot below shows the distribution of non-dimensional surface concentration levels (\(\chi=CU_{\infty}h^2/Q\) where
\(Q\) is the tracer volumetric flow rate) for the flat plate case from a selection of tracer source stack heights.

\(Q\) is the tracer volumetric flow rate) for the axisymmetric hill and 2D ridge cases from a selection of tracer source stack 
locations and heights.
