Hydraulics of Circular Culverts

ACPA-Website-Icon-Hydraulics-Of-Circular-Culverts-DD10-1Design Data:  Hydraulics of Circular Culverts (54" - 90" diameter pipe)

The hydraulic design of culverts establishes the minimum pipe size which has the sufficient capacity to discharge a required flow within an allowable headwater depth. For circular culverts, one of the principal factors influencing hydraulic capacity is pipe length, slope, surface roughness and inlet geometry also influences capacity depending on whether the culvert is operating under inlet control or outlet control.
