Abstract

Suspended poly disperse substance dispersion in a water body is simulated in the case when the spread area is considerably larger than the depth of the water body. The efficient two-dimensional methods is developed taking into account interactions between bottom and substance, substance faction index and vertical source position. Stochastic discrete clouds method is suggested taking into consideration «4/3 low». This method combines the advantages of stochastic discrete particles method and discrete clouds method. Stochastic discrete clouds method is tested by the comparison calculation results and analytical solution for the model problem oj pollutant dispersion from time-continuous point source.
