    Various experiments and numerical simulations have demonstrated that distributed rough- ness exhibits a ‘shielding effect’ whereby transition due to large-amplitude roughness elements within the distribution occurs at a higher Rekk than if those elements were positioned on an otherwise flat surface. While this effect has been observed, it has not yet been captured in a theoretical model that could predict shielding effectiveness in new situations. As a first approximation, triple-deck asymptotic theory will be applied to simplified two-dimensional distributed roughness using a no-shear boundary condition applied at y = 0 over dips in the surface geometry. Results of this approach will be compared to equivalent no-slip conditions to assess the usefulness of this modeling approach.
