Culvert

/kˈʌlvɜːt/

/ˈkəɫvɝt/

Culvert

a structure, typically made of concrete or metal, that allows water to flow under a road, railway, or other obstruction, helping to prevent flooding and maintain the natural flow of water

Examples

1. In outlet control flow, conditions downstream of the culvert can affect the flow rate.

2. The culverts then emptied into large trenches, which just ran down the street even on major thoroughfares.

3. This one is a culvert with a submerged outlet flowing full.

4. So the culverts and plot will carry over into the next episode as well as Sherlock and Mycroft sisters.
