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.
  • The term is used specifically for structures that pass a man-made barrier, distinguishing it from a simple ditch or open channel.
Examples
  • Noun:
    • The heavy rain washed debris into the culvert, causing a blockage.
    • The county is replacing the old metal culvert under the country road with a larger concrete one.
    • A family of otters has made its home in the large culvert beneath the highway.
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.
    • The new bridge project includes the installation of a three-cell box culvert.
Variants and Related Words
  • Culverting (gerund/noun): The action or process of installing culverts.
    • The culverting of the stream was necessary for the new housing development.
  • Arch culvert: A culvert with an arched top, often made of stone or brick.
  • Pipe culvert: A common type of culvert made from a large-diameter pipe, usually of corrugated metal or plastic.
Synonyms
  • Conduit: A channel for conveying water or other fluid. (More general; a culvert is a type of conduit.)
  • Drain: A channel or pipe for carrying off surplus water. (A drain can be open or enclosed, while a culvert is specifically enclosed and passes under an obstruction.)
  • Storm drain: A system for draining excess rain and ground water. (A culvert can be part of a storm drain system.)
Related Phrases
  • "Culvert outfall": The point where the water exits a culvert.
    • Erosion control mats were placed at the culvert outfall.
  • "Culvert inlet": The point where water enters a culvert.
    • A grate was installed at the culvert inlet to catch large debris.
