Abstract:

Fluorescent particle tracer experiments were conducted to investigate the pollutant transport and dispersion in the north-alpine Loisach river valley. Experimental procedures are outlined. Analysis of data for a variety of meteorological conditions including inversion cases is presented. In all cases the dilution rates were greater than those obtained by the Gaussian plume model with a sigma scheme applying to flat terrain. Highest tracer concentrations were observed with a capping inversion layer. In the theoretical part of the straight channel model developed by Gotaas is reviewed. Author
