Five different colors of fluorescent pigments were used successfully to index the movement of soil particles quantitatively and qualitatively. Sediment was collected from 32 micro-runoff collectors over the w inter and snowmelt period of 1968, and over the summer period of the same year. Rates and patterns of actual soil particle movement were obtained from 15 transects (each about 15 meters long), representing the different site characteristics. Results indicated that creep erosion was the most important mechanism of soil movement in the alpine. On sites exposed to wind action, wind erosion was responsible for movement of soil particles less than 2 mm in size. Snow deposition, frost, rain-drops, wind, grazing, slope, vegetation and microtopography were the most important factors in accounting for surface soil movement in this alpine area.doctoral dissertationsengCopyright and other restrictions may apply.
