Culvert Design:
|
|
Culvert Design |
|
Culvert Selection - Box |
- Calculate the initial trial culvert size for the design of a box
culvert.
|
|
|
Culvert Selection - Round |
- Calculate the initial trial culvert size for
the design of a round shaped culvert.
|
|
Culvert Selection - Other |
- Calculate the initial trial culvert size for
any shape culvert, inculding culvert shapes other than box and round.
|
|
HW - Submerged Inlet - IC |
- Calculate the headwater depth (HW) for a
culvert under inlet control (IC) with a submerged inlet.
|
|
HW - Unsubmerged Inlet - IC |
- Calculate the headwater depth (HW) for a culvert under inlet
control (IC) with and unsubmerged inlet.
|
|
Round Culvert - Head - OC |
- Calculate the head (H) for a round culvert
under outlet control (OC).
|
|
Arch Pipe - Head - OC |
- Calculate the head (H) for an arch pipe
culvert under outlet control (OC).
|
|
Square Box - Head - OC |
- Calculate the head (H) for square box culvert
under outlet control (OC).
|
|
Rectangle Box - Head - OC |
- Calculate the head (H) for
rectangle box culvert
under outlet control (OC).
|
|
Any Shape - Head - OChape - Head - OC |
- Calculate the head (H) for any culvert with
any cross section shape under outlet control (OC).
|
|
Tailwater Depth (ho) |
- Calculate the tailwater depth below the top of outlet barrel for a culvert.
|
|
HW Depth - Outlet Control |
- Calculate the headwater depth (HW) of a culvert under outlet
control (OC). Requires that the head (H) be calculated first by one of the
above calculations.
|
|
Culvert Outlet Velocity |
- Calculate the outlet velocity of a culvert.
|
|
Culvert Design Problem 1 |
- Size a concrete culvert pipe crossing under a county road for the following design conditions: Q = 35 cfs; maximum headwater elevation is 104.6; upstream flowline elevation is 100.1; downstream flowline elevation is 99.7; culvert length is 58 ft and the culvert will project from fill with no headwalls.
