Flow depth
Webd c = critical flow depth; H = head loss (m) Skimming flow regime. Under a skimming flow regime, water flows in a coherent stream down the step. Water skims the top of each step as it flows down the chute. Recirculating vortices are developed between each step which allow the water to flow over the top of the vortices and skim over each step.
