    Abstract

    This study will be providing an insight into soil surface roughness and whether the addition of sodium chloride hinders or helps the process of soil surface smoothing during rainfall. A rainfall simulator was used for half an hour over 8 samples, four containing sodium chloride and four containing distilled water. Digital photos were taken through the rainfall simulation. And the samples digitally scanned before and after the experiment. Analysis took form of analysing data in the form of variograms, wireframes, boxplots and histograms. The study showed that there did not appear to be a relationship between salt and the effect of the soil surface smoothing. Modifications could have been used to make it a better study; these improvements will be taken into account in further studies of this kind.
