Physical description of peculiarities of such flow is given in terms of the model of a penetrable roughness (PR). The experimental setup and obtained results are discussed. Measurements were made for the smooth boundary, the boundary with the single obstacle, and the PR-boundary. Comparison of the data allowed to distinguish the parameters characterizing the, so called, canopy vorticity. %8 2002-08-01
