Original Abstract

A numerical modelling based on the finite volume method is used for a detail study of the relation between a wind velocity above buildings roofs and a near-ground air velocity in the city area. To simulate traffic, an original model is used that takes into account traffic density, speed of cars and number of traffic lanes (Jicha at al., 2000). The predicted near-ground air threshold velocity of re-suspension at the studied street canyon is compared with two theoretical studies on particle re-suspension from horizontal surfaces. The wind threshold velocity of re-suspension is derived from a long-term measurement carried out in the city of Brno.
