16. Abstract 

This report updates the Iowa Department of Transportation (DOT) design procedures for circular, slope-tapered concrete 

culverts. The current practice is to use the design coefficients for a square-edged, circular concrete culvert with a headwall that 

are found in Hydraulic Series No. 5 (HDS-5). New inlet control design constants and entrance loss coefficients were calculated

for the slope-tapered culverts and then compared with the HDS-5 coefficients (square edge). In addition, various reducer 

lengths and taper ratios were also studied to determine what impact, if any, they have on the design coefficients. All of the 

laboratory testing was done at the Federal Highway Administration’s Turner-Fairbank Highway Research Center located in 

McLean, Virginia.

1. INTRODUCTION 

 The purpose of this research report is to update the Iowa Department of Transportation 

(DOT) design procedures for circular, slope-tapered concrete culverts. The current practice is to 

use the design coefficients for a square-edged, circular concrete culvert with a headwall that are 

found in Hydraulic Series No. 5 (HDS-5). New inlet control design constants and entrance loss 

coefficients were calculated for the slope-tapered culverts and were then compared with the 

HDS-5 coefficients (square edge). In addition, various reducer lengths and taper ratios were also 

studied to determine what impact, if any, they have on the design coefficients. All of the 

laboratory testing was done at the Federal Highway Administration’s Turner-Fairbank Highway 

Research Center located in McLean, Virginia. 

2. EXPERIMENTAL SETUP 

 The experimental setup was constructed primarily of plywood and consisted of a 2.43-mlong by 2.43-m-wide headbox, and a 1.21-m-wide by 2.43-m-long tailbox, which was located 

4.5 m downstream of the headbox. The slope-tapered inlet and culvert barrel spanned the 4.5 m 

between the headbox and the tailbox. The test matrix included two Iowa DOT precast culvert 

inlets, a 20-degree elbow, 11 reducers, and 4 different culvert barrel diameters. Prototype-tomodel scaling ratios of 6.783 to 1.0 and 4.174 to 1.0 were used. 

 A sketch of the experimental setup is shown in figure 1. The elbows and culvert barrels 

were constructed of clear plexiglass. The two inlets and the reducers were fabricated out of 

galvanized sheet metal. For each test condition, an inlet was connected to the upstream end of 

the elbow and a reducer was attached to the downstream end. These three pieces formed the 

slope-tapered inlet. A 3.66-m-long pipe was attached to the downstream end of the reducer. A 

detailed drawing of the slope-tapered inlet is shown in figure 2. The dimensions for the two 

Iowa DOT precast inlets that were tested are shown in figures 3 and 4. The 20-degree elbow 

section is shown in figure 5. The 11 reducers that were tested are detailed in figures 6, 7, 8, and 

9. 

 Fourteen pressure ports were inserted along the bottom of the culvert setup to measure 

hydraulic depth. These depths were measured using a pressure transducer and the Labtech 

Notebook software package. Two in-line electro-magnetic flow tubes measured the discharge. 

 Water entered the headbox through two inflow pipes and flowed over a broad-crested 

weir. This helped produce a uniform flow field and reduced the upstream velocity to virtually 

zero. The flow entered the culvert inlet, passed through the elbow, reducer, and barrel, and was 

discharged into the tailbox. The tailbox had an adjustable tailgate that created a backwater effect 

that was used to study the culverts under outlet control conditions.

3. TEST MATRIX 

 The Iowa DOT guidelines, as shown in table 1, include the specifications for: (1) 

allowable diameter (D) reductions from the inlet pipe to the main barrel pipe and (2) minimum 

barrel slopes required to maintain supercritical flow at 0.8*D with an assumed Manning 

roughness coefficient (n) value of 0.012 for various design discharges. Iowa DOT also 

recommends a 4.0-ft (1.2-m) reducer length for each 6.0-in- (152.4-mm-) diameter reduction. 

Table 2 shows the test matrix that was set up to recommend modifications to the Iowa DOT 

guidelines for slope-tapered pipe culverts.

Notes: * The entries in bold reflect the Iowa DOT recommended design conditions for the diameter reductions. 

** The Barrel diameters are not exact model sizes, but are the closest plexiglass tube sizes that were 

available commercially. Exact models would have been 9.73 in (247.1 mm) for the 66-in barrel and 

8.846 in for the 60-in (1676.4-mm) barrel.

 Series 1 and 5 were intended to verify the minimum slope criteria and to determine how 

performance was affected by discharges other than the design discharges outlined in the Iowa 

DOT guidelines. Series 2, 3, and 6 were intended to check the reducer length criteria. Series 4 

and 7 were benchmark tests for the precast inlet by itself (without the bends and reducers) and 

were intended to derive new design coefficients to replace the HDS-5 chart 1, scale 1 (chart 1/1) 

coefficients that had been used previously for lack of better guidelines. 

 Another series of tests was conducted to model the HDS-5 chart 1/1 inlet, which is 

described as square edge with headwall for a circular concrete culvert. This series was 

performed primarily as a verification of the test procedures to determine if it was possible to 

duplicate the HDS-5 results. 

 Prototype-to-model scaling ratios were selected that would maximize the pumping 

capability of 5.0 ft3

/s (0.14 m3/s) and minimize model fabrication costs. Standard 12-in- 

(304.8-mm-) diameter acrylic tubing was used to model both the 78-in (1981-mm)and the 48-in 

(1219-mm) inlet diameters. The inside diameter of the plexiglass tubing was actually 11.5 in 

(292.01 mm), which resulted in length scaling ratios (Lr) of 6.783 for the 78-in (1981-mm) inlet 

and 4.174 for the 48-in (1981-mm) inlet. Using the dimensionless Froude number as a scaling 

parameter, the following scaling ratios can be derived: 

 Lr = LengthPrototype/ LengthModel = 6.783 for the 78-in inlet 

 = 4.174 for the 48-in inlet 

 Wr = wall thickness ratio = Lr

 Qr = Qprototype /Qmodel = Lr

2.5 

 = 119.8 for the 78-in inlet 

 = 35.6 for the 48-in inlet 

 nr = nPrototype/nModel = Lr

1/6 

 = 1.38 for the 78-in inlet 

 = 1.27 for the 48-in inlet 

The 5.0-ft3/s (0.14-m3/s) pump was capable of modeling 175 ft3/s (4.96 m3/s) for the 48-in 

(1219-mm) inlet and 600 ft3

/s (16.99 m3/s) for the 78-in (1981-mm) inlet. It was not feasible to 

model Manning’s n, but it was measured for the model to document whether it was above or 

below the value assumed for the Iowa DOT guideline design table. 

 After the model was set up, it was relatively easy to run several discharges for each test 

series. Some of the slopes were deleted after it was determined when and where the shift from 

inlet control (presumed for the Iowa DOT guideline table) to outlet control occurred. In all, there 

were 18 runs where the culverts were operating under inlet control, 17 runs under outlet control, 

8 benchmark runs for the precast inlets, and 4 runs for the special HDS-5 verification test. 
 15 

 The goals of the test matrix can be summarized as follows: 

 • Develop inlet control design coefficients for the Iowa DOT models. 

 • Develop inlet loss coefficients for the Iowa DOT models (to be used in outlet 

control 

 analysis). 

 • Study the effect of reducer length and taper ratio (D2/D1). 

 • Compare the performance of the HDS-5 benchmark inlets versus the Iowa DOT 

 models. 

The data for all of the runs are presented in Appendix B. 

4. CULVERT ANALYSIS AND RESULTS 

Inlet Control

 Current Iowa DOT practice is to use form 1 of the HDS-5 unsubmerged inlet control 

equations, which can be expressed as: 

S

AD

Q K

D

H

D

H m

w c 0.5

 

 = + (form 1 equation) 

Where: 

Hw = headwater depth, m 

D = culvert barrel height, m 

Hc = specific energy at critical depth = yc + Vc

2

 / 2g, m 

A = cross-sectional area of culvert barrel, m2

Q = discharge, m3/s. 

K1, m1 = design coefficients for the form 1 equation 

S = design coefficients for the form 1 equation 

The HDS-5 chart 1/1 design coefficients are based on the form 1 equation. The intention was to 

derive new design coefficients for the prefabricated inlet to improve the accuracy of the current 

design procedure. For many of the Iowa DOT tests, the measured Hw was nearly equal to the 

computed Hc value. The two terms tended to cancel each other out and as a result, the K1 and m1

terms were difficult to calculate. An attempt was made to estimate the average velocity in the 

headbox and to add a velocity head component to Hw, but it was not possible to consistently get 

positive differences between the Hw and Hc terms. The data suggest that the current Iowa 

procedure is conservative if any entrance loss is added to the computed specific head (Hc). 
 16 

 An alternative is to use the HDS-5 form 2 unsubmerged inlet control equation that 

incorporates Hc and the slope correction terms into the design coefficients. It is an easier form of 

the equation to use because there is no need to calculate Hc, which is a tedious calculation for 

circular culverts. The form 2 equation that was used to analyze the data can be written as:

Where 

c, Y = design coefficients 

 At higher discharges, the barrel of the culvert would fill up or flow full. This indicated 

that the culvert was no longer flowing under inlet control conditions but under outlet control 

conditions. Therefore, it was very difficult to obtain enough data to accurately calculate the 

submerged inlet control design coefficients. Slopes of up to 5 percent were tested, and it was 

noted that whenever the Hw/D ratio neared 1.2, the culvert barrel often began flowing full. 

Consequently, it was difficult to obtain accurate c and Y values. 

 Regression results for the form 2 unsubmerged inlet control equation and for the 

submerged inlet control equation are summarized in table 3. The results for each of the 

individual runs are tabulated in tables 5, 6, and 7, which can be found on pages 21, 22, and 23, 

respectively. 

Table 3. Inlet control design coefficients (English units). 

Unsubmerged Submerged Inlet Configuration 

K m c Y 

Iowa DOT slope-tapered inlet 0.477 0.533 0.025 0.6593 

Iowa DOT prefabricated inlet 0.510 0.550 0.021 0.823 

HDS-5 square edge w/headwall 0.574 0.543 0.038 0.734 
 17 

Note that the HDS-5 inlet control equations are not dimensionless throughout. The 

coefficients, listed in table 3 above are directly comparable with the HDS-5 coefficients. English 

units must be used for the table 3 coefficients to apply. The current version of HDS-5 

coefficients, are applicable only if English units are used. One remedy would be to include the 

acceleration of gravity in the discharge intensity term to make it dimensionless, but that would 

change all of the coefficients that have the acceleration of gravity built into them. The 

conversion of coefficients from one system to the other is as follows: 

 m = exponent is the same for either system of units (English or SI metric) 

 K = SI units = K (English units)*(0.3048)m/2

 c = SI units = c (English units)*(0.3048) 

 Y = constant is the same for either system of units 

Outlet Control

 When the culvert barrel begins to flow full, it is no longer just the inlet that exclusively 

governs the headwater depth. It is an accumulation of losses starting from the tailwater at the 

outlet, proceeding through the culvert barrel, and including the entrance losses at the inlet. 

Although a culvert flowing partially full could conceivably be in either inlet control or outlet 

control, a culvert flowing completely full throughout must be in outlet control. For many of the 

experiments involving the Iowa DOT slope-tapered inlets, the culvert barrel did fill up at the 

higher discharges, even when the barrel had a free outfall, i.e., no tailwater. Therefore, it was 

considered useful to document the entrance loss coefficients for outlet control as part of this 

study. For outlet control, the energy loss is expressed as a simple entrance loss coefficient (ke) 

multiplied by the culvert (or pipe) barrel velocity head to determine the energy loss through the 

entrance. This coefficient is dimensionless, is independent of the system of units, and is usually 

taken to be constant for a particular inlet. The experimental values varied slightly, but the 

highest values measured were reported for design purposes. The procedures used to determine 

the ke values are documented within this section. 

 The total entrance loss (Hetot) was measured for outlet control tests by projecting the 

energy grade line (EGL) in the headbox and the EGL for the culvert barrel to a common plane at 

the upstream end of the culvert barrel, as illustrated in figure 10. It was felt that there was 

enough overall length in the inlet to warrant rating the friction component separately from the 

minor losses attributed to the converging flows in the entrances, the flow direction changes in the 

bends, and the flow contraction in the reducer.

 The important thing to note is that the ke value reported does not include friction in the 

overall inlet, which could be more than 20 ft (6.1 m) long in the full-scale installation. For a 

circular pipe flowing full, R = D/4. 

 Manning’s n can be backcalculated by measuring the friction slope in the main culvert 

barrel for several full-flow tests and substituting it into the formula:

Where: 

Sf = friction slope, which can be measured by the slope of the EGL, m 

The calculated n values averaged 0.010, which is a reasonable value for the plexiglass piping. It 

was not possible to do the same for the reducers, which were fabricated from sheet metal, but it 

was assumed that the roughness of the metal was close enough to the plexiglass to use the 0.010 

value throughout.

 Figures 11 and 12 compare the unsubmerged and the submerged laboratory data for the 

Iowa DOT prefabricated inlet, the square-edge headwall inlet, and the HDS-5 chart 1/1 

coefficients. The laboratory results for the square-edge headwall correspond well with the HDS5 coefficients. The figures also show that the Iowa DOT prefabricated inlet is more efficient 

than the other two inlets. The results for each of the individual runs are shown in tables 5, 6, and 

7, which can be found on pages 21 through 23, respectively. 

5. DISCUSSION OF RESULTS 

The design coefficients and ke values listed in tables 3 and 4 would allow one to design 

the Iowa slope-tapered pipe culverts for a full range of discharges. Figures 11 and 12 show that 

the prefabricated inlet is more efficient than the HDS-5 chart 1/1 inlet. Iowa DOT had been 

using the HDS-5 inlet to represent both the unsubmerged and the submerged inlet control 

conditions. These figures also verify that the test procedures used in this study are consistent 

with previous research done for HDS-5. 

 Figures 13 through 16 show whether there is any advantage to using multiple reducer 

lengths to go from a large-diameter pipe to a smaller one. Figure 13 shows that there is no 

discernable advantage to using more than one reducer length for the 48-in- to 36-in- (1219-mmto 914-mm-) diameter reduction at the design discharge, which was modeled using 0.076 m3

/s. 

The Iowa DOT guideline is for two reducer lengths. Figure 14 shows some improvement by 

using two reducer lengths, but no additional improvement by using three reducer lengths for the 

78-in- to 60-in- (1981-mm- to 1524-mm-) diameter reduction at the design discharge, which was 

modeled at 0.070 m3

/s. Current Iowa DOT guidelines call for three reducer lengths at this 

discharge. Figure 15 seems to show a slight improvement by using two reducer lengths. 

However, the figure shows that there is no improvement by using three reducer lengths for the 

78-in- to 66-in- (1981-mm- to 1676-mm-) diameter reduction. The Iowa DOT guideline is two 

reducer lengths. Figure 16 shows no improvement by using two reducer lengths rather than one 

for the 48-in- to 42-in- (1219-mm- to 1067-mm-) diameter reduction. The Iowa DOT guideline 

is for one reducer. Based on these observations, it appears that the number of reducers 

recommended by Iowa DOT is slightly conservative, usually by one reducer.

6. CONCLUSIONS 

 Iowa DOT should use form 2 of the unsubmerged inlet control design equations found in 

HDS-5. Examination of the procedures for calculating Hc showed them to be valid. However, 

for slope-tapered inlets, form 2 of the unsubmerged inlet control equations works better. 

 The taper ratio and the number of reducers do not seem to affect the energy losses 

through the slope-tapered inlets, nor do they seem to affect the transition between inlet control 

and outlet control for smaller culvert slopes. Tables 5, 6, and 7 summarize the design and 

entrance loss coefficients. Note that the friction losses must be calculated and added to the He

values to yield the total head losses for each inlet.

7. ADDITIONAL STUDIES 

 The following is a list of future studies that Iowa DOT may wish to consider that could 

address outstanding technical issues: 

 Test the slope-tapered inlets without the reducers in order to isolate the head losses 

associated with just the reducers. 

 Test additional slopes for the inlet control runs. The culvert barrel was often filling up 

when Hw/D neared 1.2. Submerged inlet coefficients could be calculated with the 

additional data. 

 Perform more detailed inlet control tests that determine exactly where the flow translates 

from inlet control to outlet control. The effect of the number of reducers can also be 

examined to see if it has any effect on where the transition from inlet control to outlet 

control occurs.

APPENDIX A. 

CALCULATING SPECIFIC HEAD AT CRITICAL DEPTH 

 Form 1 of the inlet control equations found in HDS-5 includes the specific head at critical 

depth, which is defined as: 

g

V H y c

c c 2

2

= + (1) 

Where: 

 Hc = specific head at critical depth, m 

 yc = critical depth, m 

 Vc = critical velocity, m/s 

 g = gravity, m/s2 

 Critical velocity is calculated by applying the continuity equation over the cross-sectional 

area of the barrel. For rectangular cross-sections, the area is simply the depth times the width. 

However, for pipes flowing partially full, the calculations for cross-sectional area are more 

complicated. Figure 22 shows the parameters involved with such a calculation. The method for 

calculating the cross-sectional area in a partially full pipe is accomplished using the following 

geometric relationships:

 With the above relationships established, a relatively simple procedure can be used to

1. Plug Q and r into equation 9 and solve for 2. This can be accomplished by trial and 

error or by a direct solution using a computer program or a programmable calculator. 

2. Solve for yc using equation 3. 

3. Solve for AF using equation 2. 

4. Calculate Hc using equation 1 and substituting Q/AF for Vc.
