dc.description.abstract Determines the areas of potential wind erosion in the Cape Province through the use of two different models. The models were developed and applied in semi-arid areas and thus are considered applicable in South Africa. They are the Wind Erosion Equation developed by Chepil, Woodruff and Siddoway, and Lynch and Edward's Model for the Analysis of Limited Climatic Data. There are two aspects to soil erosion by wind - the erodibility of the soil and soil erosivity. Methods to control wind erosion are based on decreasing erosivity through the establishment of shelterbelts and decreasing erodibility by improving plant cover, aggregate stability and moisture retention properties. A number of models have been developed to overcome the difficulties of wind erosion measurement and to predict soil loss. Two of these models are applied to conditions in the Cape Province. It is, however, concluded that neither of these models can be directly applied to conditions in the Cape Province. The seasonal rainfall distribution and the uneven distribution of the data points contribute to the ineffectiveness of the models. The greatest problem, however, is the importance of management in determining whether or not wind erosion occurs. As a result, although the models illustrate the general climatic trends affecting the susceptibility of an area to wind erosion, the lack of a management factor accounts for the lack of detail. en
