| Many surface processes, i.e. in_ltration, depressional storage, gas exchange, are a_ected by soil surface microrelief. Conversely, many surface processes, i.e. erosion, deposition also cause changes in soil surface roughness. Therefore, quanti_cation of surface roughness can enhance the understanding of these physical processes. Recent research has shown the usefulness of multifractal analysis in soil surface roughness characterization. We employed it to characterize topographical point elevation data sets acquired by high resolution laser scanning for assessing the e_ect of simulated rainfall on microrelief decay. Three soil surfaces with di_erent initial states or composition and rather smooth were prepared on microplots and subjected to successive events of simulated rainfall. Soil roughness was measured on a 2 _ 2 mm2 grid, initially, i.e. before rain, and after each simulated storm, yielding a total of thirteen data sets for three rainfall sequences. Here we analyze, to what extent the structure function in 2D of soil surface microrelief can describe the erosion process by heavy simulated rain and its interpretation. | |
