Comparisons of Sidewall Correction of Bed Shear Stress in Open-channel Flows

  title={Comparisons of Sidewall Correction of Bed Shear Stress in Open-channel Flows},
  author={Nian-sheng Cheng and Lloyd Hock Chye Chua},
When investigating sediment transport in laboratory open-channel flows, it is often necessary to remove sidewall effects for computing effective bed shear stress. Previous sidewall correction methods include some assumptions that have not been completely verified, and therefore different values of the bed shear stress may be obtained, depending on the approach used in making sidewall corrections. This study provides a quantitative assessment of the existing correction procedures by comparing… CONTINUE READING
