Figure 3. Locations used to determine channel depth.

(a) Illustration of step-pool morphology and location to determine channel depth (d). Depth is estimated at the step-pool break from the thalweg to the height of bankfull conditions. Note that D/Wb in this schematic is approximately equal to 0.3.
(b) Illustration of riffle-pool morphology and location to determine channel depth (d). Depth is estimated at the riffle-pool break from the thalweg to the height of bankfull conditions. Note that D/Wb in this schematic is <0.01.
