The dependence of the plume flow on turbulent mixing is first investigated. Wind effect is then added in order to reproduce real conditions encountered during a field campaign performed by the LSEET. Numerical results concerning the suspended matter are than compared with experimental data and this confrontation reveals itself encouraging.<P>
