The Urban Canopy Model that has been widely used as a practical methodology to estimate a friction force generated by a bulk ol building roughness, was precisely confirmed from the validation viewpoint. In three series of experiments, both disposition and height of building models were particularly concerned. In short, following three schemes for the models were intrigued; -Arrayed in both staggered and normal rectangular block consisting of same height models -Arrayed in both staggered and normal rectangular block consisting of models combined two heights -Random shaped model derived from a certain real city With respect to the space-averaged vertical wind profiles, good agreement between the experiments and calculations was obtained in any cases. That led to verify the fact that the Urban Canopy Model was deemed as one of the most effective procedures to predict the wind characteristics in urban canopy layer.
