Description :
In this study, conducted in semi-arid Botswana and Tanzania, soil surface and subsoil characteristics were studied along transects. Factors such as surface seals, soil texture, vegetation cover, slope gradient and land use were observed. The infiltration capacity was measured by means of the double-ring method and the dropper method. It was shown that the occurence of surface seals was related to soil conditions, vegetation cover and microtopography. Therefore, aerial photographs can give easy access to factors which influence rainfall partitioning.
