Abstract : The study of the turbulent diffusion over a rough surface in the wind tunnel was utilized with the concept of momentum defect super-position in the wakes of an array of roughness elements. Based on this concept, the characteristics of each factor of turbulent diffusion are analyzed and the results are confirmed experimentally. From agreement between theory and experiment, the concept, the turbulent shear flow consists of the combination of the individual wake flows, is confirmed. (Author)
