Discussion of the results of experiments using simulated rainfall. It is shown that, because film thickness increases, the direct impact of rainfall on sediment transport decreases with slope length.

Flow detachment, sediment transport and interactions between flow characteristics and sediment load are discussed here. Descriptions of the interactions between sediment load and flow characteristics, namely mean flow velocity, obtained through
the proposed algorithm agree with the empirical trends. Also transport capacity seems to be adequately described.

In this paper travel distance will be used to refer to horizontal distances. A particle movement such as rainsplash or fluvial bedload transport shows at least the potential for variations in travel distance with grain size. Experimental data also
show a considerable dispersion in the travel distances within each grain size class. This behaviour also contrasts strongly with that for a mass movement. Transporting capacity cannot generally be measured directly, but must be derived from
