solifluction

a slow movement of soil or rock debris down an incline, usually as a result of lubrication by its water content.

Clear evidence of climate-driven modifications of landforms, such as patterned ground or solifluction lobes, would, no doubt, require a much longer period of monitoring.

In the alpine area of the Southern Carpathians, the alpine geomorphological landscape is dominated by glacial landforms (glacial cirques, throughs, moraines, erratics and roches moutone) and periglacial features (rockglaciers, talus cones and scree slopes, block fields, rock streams, cryoplanation terraces, patterned ground, solifluction forms etc.
Radiocarbon dating evidence for the initiation of solifluction ca.
This rapid establishment of forest and reduction in solifluction resulted in a stabilization of the surrounding slopes, causing an abrupt drop in erosion and surface runoff, as indicated by the sharp decline in mineral influx at Splan Pond and the return to organic sediment evident at all three sites.
He has reconstructed the palaeoecological evolution in the present periglacial belt of this high semiarid Mediterranean massif studying two sedimentary records: solifluction lobes and mountain lakes.
The most typical processes were thawing of frozen soils, glaciokarst (in Poozerye), thermokarst, and solifluction (in periglacial areas) processes, and descent of periglacial water reservoirs.
The Early and Middle Pleistocene covers include a large proportion of angular clasts, pointing to the role of intensive solifluction within glacial stages.
However, the bowhead whale bones described by Atkinson and England (2004) are anomalously old compared with dated driftwood and marine shells collected from the same shoreline, suggesting that the animal either sank prior to being exposed by falling sea level, or experienced post-stranding redeposition, likely due to solifluction.
Coastal profiles and their Pleistocene evolution correspond to the slope-over-wall model (Bird, 2000), where the cliffs were degraded by periglacial processes during the Glacial period, with the altered mantle moving downslope by solifluction and translational landsliding.
There are no indications of mass movement or solifluction and the differing surface features appear to relate to natural variation in depositional conditions during ice retreat.
Wind erosion following salinization, solifluction, and deflation are greater for particles 0.
