Outlet Control

 

Culverts flowing with outlet control can flow either with the culvert cell full, or with the cell part full for all of the culvert length.

 

The following figures show different types of culverts flowing under outlet control as shown in Figure 7.2 (Figure 27.7 (MSMA,2000) or Figure 18.3 (MSMA,2011):

  1. Both inlet and outlet submerged
  2. Inlet submerged but not the outlet
  3. Inlet submerged and the cell part full over part of its length
  4. Inlet and outlet not submerged and flowing part full over its entire length.
