| Definitionskos:definition | The elongate mound (tail or shadow) deposited immediately downstream of an obstacle (crag) in the path of flow (tail length centimeter to decimeter). They begin to appear on muddy and sandy substrates in association with surface lineation (0.1–0.3 m/s). They become more prominent and widespread, and occur in association with comet scour and erosional pluck marks, at slightly higher velocities (<0.4 m/s). Mound and tail is the term used for similar structures where the obstacle is a biogenic (or other) mud mound. There may also be a genetic link with rhomboid ripples or rill marks, which develop on generally planar beds at flow velocities slightly greater than those required for surface lineation (Stow et al., 2009). |
