| Zusammenfassung |
| The spatial variability of preferential pathways for water and chemical
transport in a field soil, as visualized through dye infiltration
experiments, was studied by applying multifractal and wavelet transform
analysis (WTA). After dye infiltration into a 4 m² plot located
on a Vertisol soil near College Station, Texas, horizontal planes in the
subsoil were exposed at 5 cm intervals, and dye stain patterns were
photographed. Box-counting methods and WTA were applied to all of the 16 digitalized
high-resolution dye images and to the dye-mass image obtained merging all sections.
The well-known Devil's staircase multifractal was also used to illustrate wavelet-based analysis. Our results suggest that
wavelet methods can complement box-counting analysis in the context of
multiscaling structure analysis. |
