Convey water beneath roads and away from sites.
Culverts convey streams under roads: inlet or outlet control, headwater depth, barrel size, and fish passage. Stormwater drainage uses inlets, pipes, manholes, and detention. Sustainable drainage (SuDS) emphasises infiltration and storage.
A box culvert is sized for the 50-year storm with limited headwater.
Culverts and drainage pipes carry water under roads and away from sites, and their undersizing causes flooding and road damage.

Culverts and drainage pipes carry water under roads and away from sites, and their undersizing causes flooding and road damage.
Debris, sediment and poor inlet design can reduce capacity, so inlets and screens need regular checks.
A structure at the inlet or outlet of a culvert that protects the embankment and guides the flow.
Typical applications include sizing a culvert under a road to pass a design flood, designing a surface drain to collect runoff from a car park and checking the outlet of a pipe to avoid erosion at the discharge point.
Study "Open channel design" first (topic 76 of 112 in Civil & Structural). It covers the groundwork this topic builds on.
HW/D ratio. Energy dissipators. Pipe sizing by Manning.
A box culvert is sized for the 50-year storm with limited headwater.
The next topic is "Water supply engineering", which builds directly on this one.
It is classed as Advanced in Civil & Structural (topic 77 of 112). It is an advanced topic. It assumes you are comfortable with the intermediate topics in Civil & Structural.
