Summary The analytical equation of Rose was more successful than the models of Burns and Addiscott in predicting movement of chloride through a soil on Upper Chalk under irrigation and winter rainfall. The two models required water inputs to be divided into 5 mm increments. When this was done the model of Addiscott was more successful than that of Burns although both then gave predictions of acceptable accuracy for practical purposes. The analytical equation of Rose requires a value for solute dispersivity. This was obtained from the experimental measurements, but the value used (3 cm) was found not to be critical.
