## Abstract The response of the boundary layer wind profile and the surface shear to a large step change in surface roughness is predicted by three calculation methods and the predictions are compared with measurements by Bradley. The first method, which assumes that local equilibrium exists everyw

β¦ Synopsis
The testing of a simple correlation for the height of the internal layer, found from dimensional analysis, is described. It is shown that the internal layer is controlled by the larger of the upstream and downstream roughness length scales.

## Abstract A new approach using a curvilinear coordinate system that enables incorporation of a change of roughness with a zeroβplane displacement or elevation change in a boundaryβlayer model is presented. the effect of topography together with the rapid development of an internal boundary layer
Mean products of velocity fluctuations up to fourth order have been measured in a wind tunnel at the trailing edge of a flat plate, one side of which was covered with floor-sanding paper to produce a fully rough surface. This set-up permits easy comparison of structural parameters in smooth-wall and
