Submitted: Remote sensing of river discharge based on critical flow theory

  • Standing waves in rivers indicate unique hydraulic conditions that allow depth and velocity to be inferred from the spacing of the waves.
  • Critical flow theory can be used to calculate discharge based on measurements of wavelength and width made using readily available images.
  • Discharges estimated via the critical flow approach for 82 images agreed closely with discharges recorded at gaging stations (R2 = 0.98).
