According to Wikipedia, a culvert is a structure that allows water to flow beneath a road, railway, trail, or similar obstacle. Culverts are typically made from materials such as reinforced concrete, steel, plastic, or corrugated metal and are surrounded by soil to support the overlying roadway.
Culverts play a critical role in drainage systems by conveying stormwater or natural stream flow beneath transportation infrastructure. They help prevent flooding, reduce erosion, and maintain the natural movement of water while ensuring roads remain safe and accessible. Depending on project requirements, culverts are available in various shapes and sizes, including circular, elliptical, box, arch, and pipe-arch configurations.
The selection of a culvert depends on several engineering factors, including hydraulic capacity, expected flow rates, roadway embankment height, soil conditions, and maintenance requirements. Proper design and installation are essential to ensure adequate water conveyance, structural stability, and long-term performance.
In modern civil engineering, culverts are an essential component of stormwater management systems, protecting infrastructure from water damage while supporting sustainable drainage practices
