This geology image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.
It is recommended to name the SVG file “Bedforms under various flow regimes.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
Summary
DescriptionBedforms under various flow regimes.pdf
English: Bedforms formed in sand in channels under unidirectional flow. Numbers correspond broadly to increasing flow regime, i.e., increasing water flow velocity. Blue arrows show schematically flow lines in the water above the bed. Flow is always from left to right. Figure redrawn from http://www.fhwa.dot.gov/engineering/hydraulics/pubs/08090/04.cfm.
