摘要：This paper focuses in particular on clastic sediment
fluxes on talus slopes. Using orthophoto interpretation,
field measurements and GIS-techniques, a quantification of areas and volumes of active sediment transfer
related to specific landform units was achieved for different spatial scales. Closer investigation of a single
landform complex, more specifically a talus sheet/
debris cone-complex, brought to light that remobilisation can overbalance sediment input by a factor of 57.
This could be an indication of what may be expected in
the whole catchment. At present. approximately 9% of
the research area (3 km2), comprising talus slopes and
valley bottom, is characterised by sediment transfer
mainly through gravilational and fluvial processes. A
comparison of the vast volumes (117.174 m3) derived
from these active areas of recent sediment transfer
and the volume of the entire valley fill (0.07 km3) indicates, however, that the largest part must be related
to remobilised sediments and cannot be considered as
sediment input from the adjacent rockwalls. This conclusion is also supported by direct measurements of
sediment input.
