Abstract
The distribution of surface roughness in the city area can be estimated by the GIS data. And, the characteristics of the drag coefficient have been investigated based on the data obtained from a series of wind-tunnel measurements in a simulated urban roughness. Consideration is focused on the standard-deviation height of roughness. A model formula for the drag coefficient is proposed as a function of the roughness parameters, i.e. the roughness density, the mean and the standard-deviation of roughness height. This model is used for estimating the exponent of the power law.
