Computational fluid dynamics models of Rio Grande bends fitted with rock vanes or bendway weirs

Seth Siefken, Colorado State University

  • An analysis of several rock vane and bendway weir configurations on the flow through two river bends shows that rock vanes are more effective than bendway weirs at reducing flow velocity along the outer bank.
  • Velocity reduction was found to vary considerably across different geometry configurations, and an optimal configuration range for rock vanes was established.
Siefken (2019): flows around bendway weir (fig. 46) and rock vane (fig. 47)

The difference in flow field between rock vanes and bendway weirs can be explained by their geometries. Bendway weirs are built with a horizontal crest, which is completely submerged at the design flow. The submerged crest allows a relatively large portion of the flow to pass over the crest of the bendway weir. In contrast, rock vanes have a sloped crest that extends up to the waterline elevation. As a result, rock vanes block more flow area near the waterline, helping to direct flow around the tip of the structure rather than over the crest. The result is a lower unit discharge and lower velocity along the bank compared to a similarly designed bendway weir.”
