Entrance losses are computed as a function of the velocity head inside the culvert at the upstream end. The entrance loss for the culvert is computed as: The velocity head is multiplied by...

Culverts are structures used to convey surface runoff from one side of the road to another and are usually covered with an embankment composed of structural material around the entire …

The entrance loss coefficient is a function of the flow. Coefficients are often supplied by culvert manufacturers and are for relative depths (headwater depth/culvert rise) of about 1.2, well …

Some end sections, incorporating a closed taper in their design have a superior hydraulic performance. These latter sections can be designed using the information given for the …

2023年9月21日 · Many different types of culvert flow have been observed and classified. However for the purpose of design, only two types of flow are recognized. These are termed inlet control …

For inlet control, the discharge capacity is controlled at the upstream or inlet end. Factors that have an effect on the culvert performance under this condition are the headwater elevation, …
