Fig. 10. Comparison of particle dispersion (spray drift) model with data from Bird et al. (1996)(standard case) for three wind speeds u. Parameters: canopy height h_c = 0.15 m; leaf dimension d_c = 0.005 m; field length x_p = 274 m; spray release height h_s = 2.5 m; initial plume height _Z0 = 1 m; median particle diameter = 250 µm; particle size distribution is log-normal with standard deviation ln(1.7); atmospheric stability is neutral (D) or slightly unstable (C).
