Definition
A bedform is a depositional feature whose genesis is through the action of a forcing fluid (e.g., air or water) resulting in the movement of the granular material, manifesting into characteristic surface morphology indicative of the flow parameters in operation.
Description
Deposits of sand and granule-size particles transported principally in saltation in flowing fluids organized into a regularly repeated pattern which forms on a solid surface because of the shearing action of a fluid. Bedforms can be aeolian or subaqueous, erosional, or depositional surface features. Fluids in which they form can be wind, water stream, or dense mixtures of particles and gases (e.g., volcanic or impact-induced base surges) (Wilson 1972; Greeley et al. 2006).
Morphometry/Morphology
On Earth, 2D bedforms are defined as having straight crestlinesand constant crest-trough depths relative to surrounding surface level. In cross section, 2D bedforms have identical foresets and bounding surface...
