Culvert Headwalls, Wing Walls & Scour Aprons - Terra Aqua Inc.
Wing walls can be classified according to their position in plan with respect to banks and abutments. The classification is as follows: 1.

Their top width is 0.5 m, face Websection in the culvert is located either at the control section or at the outlet section of the culvert. The control section is the section where the flow changes from subcritical to supercritical flow. Webwing wall to simulate scour conditions. Results Results for the culvert with a 3.7 m wing wall height are presented in Fig. 6. Additional observations include: • in most of the models, the wing wall has a similar trend of movement and stress development (Fig. 7). At the first stage, it tends to stay in design position without much of movement. diana wedding cake
