Description
In the last decade deposition on lateral moraine embankments of glacier de Tsidjiore Nouve has been re-activated on a large scale. An attempt has been made to reconstrucl, from the dimensions of the embank­ments, average rates of debris accumulation on the moraincs during the Neoglacial period. These are compared with rates of deposition over the period 197 7-82, calculated from detailed changes in moraine profiles (sur­veyed by ground- and air-based photogrammetry) and measured rates of ice-margin ablation. At present total output of sediment, by marginal deposition and transport by melt-water streams, from glacier de Tsidjiore Nouve is in the order of 6 400- 9 500 m'/a; this suggests the possibility of a high average erosion rate within the glacier catchment of 1.55-2.29 mm/a.
