* h/r<sub>i</sub> -- Ratio of roughness element height divided by hydraulic radius taken about the top of the roughness element.
* Height of the roughened section (h)
 
 
The following figure shows the flow regimes and variables for an increased resistance energy dissipator implemented in a circular culvert.

Variables from the figure
 
* L -- Length from beginning of one roughness element  to the beginning of the next roughness element.
* h -- height of roughness element
* D<sub>i</sub> -- diameter of roughened section (opening)
