Definition

1. Noun:
   • A transverse and totally enclosed drain under a road or railway: A culvert is a structure, typically a pipe or a channel, that allows water to flow under a road, railway, trail, or similar obstruction from one side to the other. It is completely enclosed to support the weight above it.

Usage

• Culverts are essential civil engineering structures for drainage and preventing water from eroding or flooding transportation routes.

Advanced Usage

• "Culvert hydraulics": The study of water flow through culverts, important for engineering design to prevent flooding.
  • Proper culvert hydraulics ensure the structure can handle a 50-year storm event.
• "Box culvert": A culvert with a rectangular cross-section, often made of concrete.
