Abstract
The problems of the evaporation of liquid sprayed on a rough natural surface which may absorb the sprayed material in both the liquid and vapour phases and the subsequent atmopsheric diffusion of the vapour evolved, is discussed. A mathematical model for predicting vapour dosages downwind of contaminated areas of grassland is presented together with a description of numerical methods and the computer program employed to obtain solutions of the diffusion equations. Examples are given of calculations with the model from which approximate relations are deduced that can be used to develop simpler graphical methods of computation.
