Description :
This study considers changes occurring on a soil surface after exposure to simulated rainfall. The soil surface has a crop cover of artificial maize, and interest focuses specifically on the surface features produced by leaf drips. An analytical photogrammetric approach is used to examine surface morphological change at a small scale (1 mm). These topographical changes are then related to sub-surface crust development as observed by the use of impregnated polished blocks. The results reveal a cut and fill type process in which aggregate welding and breakdown operate in parallel.
