Air pollution problems in hill-basin regions become increasingly urgent along with the development of industries in such areas. One of the salient features of the pollution problems of this kind is the significant effects of the lee eddies upon the dynamic behaviours of chimney plumes. In the present article, detailed descriptions of laboratory experiments conducted in a towing tank are given. Under neutral and stable stratification conditions, various lee eddy flow patterns and corresponding dynamic characteristics of plume movement weie obtained in the laboratory simulations. Based on the experimental relationship between the plume-releasing high and the distance of plume's reattachment to the ground, criteria are proposed for chimney height designing and location choosing. Many of the laboratory measurements were compared with field data. The agreement seems quite satisfactory.
