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.

Questions

  • Does aeolian sand transport research support the use of sand bar building from HFEs as a means to provide a source of aeolian sands to preserve and protect archaeological sites?

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.”
  • "In this study, aeolian deposition, even with anthropogenic forcing via fluvial sand-bar building high flow dam releases, was found to be generally insufficient to offset the effects of precipitation-induced gullying."
