The dynamics of rainsplash erosion and the role of soil aggregate stability

FARRES, P. J.

Description :
The work of a number of authors is integrated to reveal a sequence of events occurring during rainsplash erosion. The implication of this sequence is that aggregate stability plays a central regulatory role. Using 20 iron rich soils from Mozambique it is shown that their temporal dynamics as regards splash loss is consistent with this proposed sequence, and that in addition aggregate stability does directly relate to total splash loss over a 50 minute period of rain. By now considering the soil properties a statistical model is formulated. A model which seems to imply that the central regulatory role of aggregate breakdown is only a partial answer to erodibility, as important are the characteristics of the breakdown bi-products.
