Stormwater box culvert transition

Stormwater Box Culvert Transition

Stormwater box culvert physical model: This model shows a transition from a box culvert (4.5 x 2.1 m) into two twin culverts underneath a road (3 x 1.25 m) and we were interested in quantifying the head loss throughout the transition. In the video the tailwater condition is changed slightly to show the sensitivity of the system to blockage as well as the way the system transitions from free surface flow to pressurised flow.
