Teardrop-shaped mesoscale landscape features in plan view, having a tapered downstream tail.
Streamlined forms are often semi-lemniscate in plan view and may be composed of layers (Burr 2005) and so can have terrace-like benches along their margins. Some islands may be rhomboid or diamond-like shaped.
None but see also yardangs in aeolian systems
Generally interpreted to represent a shape that is hydraulically streamlined by deposition and erosion of sediment and rock by fluid flow to minimize flow resistance.
Depositional: the channel-forming flows were ponded by local...
