        In this case the PLANT option allows to predict the
        sedimentation of the different size particles from
        the cloud driven by the wind. It is done by the model
        involving the drift-flux principles. The dependent
        variables include the staedy sedimentation velocities
        and the concentration of two group of particles with
        40 mcm and 120 mcm. The wind is directed SOUTH-WEST
        with the velocity equaled  5 m/s.
