Difference between revisions of "Aeolian Sand Transport"

Of 358 river-corridor arch sites (RM 0-240), 74 (21%) are adjacent and upwind of sandbars receiving HFE sand (Type 1 and Type 2a) that don't have some sort of topographic barrier. Of these, 43 sites are currently blocked by vegetation from receiving aeolian sand.

Collin et al. 2016:

• Aeolian deposition was found at 4 sites (30%) where partial infilling occurred preventing further erosion.
• “Despite this promise for archaeological site preservation, our observations show that gully annealing can only occur under a specific set of conditions related to fluvial sand availability and wind transport direction.”
