The next sedimentation cycle starts with development of new creeks and gullies.
The cycle starts with minor creeks or gullies, which are formed to drain the excess rainwater on a widespread interfluve area.
Establish tree checks on boundaries to reclaim gullies.
The creeks and gullies are filled by fine sand available from local higher areas.
Species associations were relatively more frequent with the lower-elevation gullies.
Diverting run-off from gullies to perennial crops.
Observations of martian gullies and constraints on potential formation mechanisms.
The "gullies" located on such isolated structures are a separate class of features, though, and these geomorphic differences are most likely related to their process of formation.
