SUMMARY

Flow through Old River low-sill control structure will be regulated in eleven 44-ft-wide gate bays. The sill for the three center bays will be at elevation -5 ft msl while the sill for the other eight bays will be at elevation 10ft msl. Flow will be controlled by multiple-leaf, . vertical-lift gates, providing a damming height to elevation 67 ft msl. Each gate in the side bays will consist of three 19-ft-high leaves, while each of the three center bays will require three 19-ft-high leaves plus a 15-ft-high leaf. Model tests were made to determine the vertical forces to which the gate leaves will be subjected by the extreme range of headwater and tailwater elevations that may occur at the structure.

A 1:36-scale model of the low-sill structure was tested first and showed that both the 15- and 19-ft gate leaves would bounce violently under normal operating conditions, producing such destructive forces in the suspension system that the elimination of the conditions causing the bouncing assumed primary importance. A 1:60-scale model of one gate leaf was then installed in a glass-sided flume so that flow patterns around the leaf could be observed. These observations established that the bouncing was being caused by periodically fluctuating pressures as evidenced by the alternate formation of vortices off the top and bottom lips of the leaf. Operation of the lower two leaves in each gate bay fastened together and relocation of the air vents eliminated the bouncing. However, the necessity of operating two gate leaves fastened together imposed considerably increased loading on the hoisting apparatus since each leaf will weigh about 80,000 or 90,000 lb. The maximum applied downpull was found to be about 190,000 lb, which, when added to the dry weight of the two gate leaves, would result in a total hoist load of about 370,000 lb. In the model the maximum downpull was reduced by about 100,000 lb by installing a projecting cover plate over the upper horizontal girder, thereby preventing the nappe from impinging upon the lower girders. Wind effects and other unpredictables, however, justify the use of the higher downpull value in selecting the prototype design hoist load.

A brief series of tests performed in a 1:60-scale section model indicated that the maximum pressure differential between the upstream and downstream sides of the gates would be 38 ft of water for a design pool of 54 ft msl and a tailwater of 20 ft msl. If a cover plate is installed over the top girder a minimum pressure of -2 ft of water on the plate may be expected.

Hydraulic Model Investigation

PART I: INTRODUCTION

1. The Atchafalaya River, a distributary of the Mississippi

through the short connecting channel of Old River, has been increasing

in capacity to such an extent as to threaten to divert the Mississippi

River through its much shorter and therefore steeper route to the Gulf

of Mexico. The following measures are proposed to control flow from the

Mississippi and prevent its capture by the Atchafalaya River: closing

off the existing Old River channel with a dam and navigation lockj con

necting the existing Mississippi River levees above and below Old Riverj

and constructing control structures in the existing Mississippi River

levee at a point about 10 miles above the mouth of Old River. The ele

ments of the control plan are shown on fig. 1. The proposed control

structures include a low-sill structure 548.5 ft long for the regulation

of normal flows and an overbank structure approximately 3393 ft long

having a sill elevation of 52 ft* for operation during flood flows. The

tests reported herein were concerned with the control gates for the low

sill structure, and constitute one phase of the model studies of this

structure.

Description of Prototype

2. The low-sill control structure will consist of eleven 44-ft

wide bays, numbered 1 to 11 from left to right looking downstream.

The center three bays will have a sill elevation of -5 ftj the four

bays on each side of the low center section will have a sill elevation

of +10ft (figs. 2 and 3). Flow through the structure is to be

controlled by multiple- leaf, vertical-lift gates . The gate leaves will

be of plate girder construction with a skinplate on the upstream side .

The skinplate will extend beyond the upper and lower girders to prevent

impingement of flow on the structural members of the gate (see fig . 4) .

3. The arrangement of the gate leaves is shown on fig . 5. One

15-ft leaf is at the bottom position in the low· section of the weir with

three 19-ft leaves above it . The arrangement is the same for the higher

weir section except that the bottom 15-ft leaf is eliminated. It is

anticipated that any individual bay either will be operated with all

leaves removed or will be completely closed . Individual gate leaves

will be raised or lowered by means of a gantry crane on tracks on top

of the piers and as each leaf is removed it will be stored in slots

provided on top of the piers . It may be necessary to open or close

the gates under any of the possible flow conditions up to and including

a pool elevation of 67 ft . This means that it will be possible for all

except the top gate leaves to have water flowing both over and under

them during their removal .

Purpose of Study

4. The gate downpull tests were initiated for the purpose of

determining the vertical forces to which the gate leaves will be sub

jected during severe operating conditions so that the suspension system

and hoist machinery can be designed for the maximum loading. Since the

possible range of headwater and tailwater elevations is extreme, it was

deemed necessary to explore this subject with a degree of accuracy that

could be obtained only by model tests.

PART II: THE MODELS AND TEST PROCEDURE

Description of the Models

5. A 1:36-scale comprehensive model of the low-sill control struc

ture, a 1:60-scale model of one gate leaf, and a 1:60-scale reproduction

of a gate bay, the two adjacent piers, and two gate leaves were used in

the study. True similarity between the models and the prototype was ob

tained by preserving geometric similarity in accordance with the Freudian

relationship which assumes gravity as the dominant flow factor. The re

sulting scale relationships are as follow:

6. All of the gate downpull tests were performed in the 1:36-scale

comprehensive model. Bay 6, the center bay in the low section of the

weir, and bay 9 in the high section of the weir were used for all of the

tests. Machined aluminum gate slots were installed in the sides of the

wooden piers flanking bays 6 and 9 so that the gate rollers would en

counter a negligible amount of friction. In these tests pool and tail

water elevations were set by means of staff gages on the abutments and

no effort was made to measure discharge.

7. The downpull measuring apparatus (fig. 6) consisted of two

pulleys mounted above the gate slots, two flexible brass cables supporting

the gate and passing up over the pulleys, a Hunter type spring scale

graduated to 0.1 lb at which the two cables terminated, and a hand winch

attached to the Hunter gage by means of a single cable of flexible brass

wire . A miniature turnbuckle was mounted in one of the cables support

ing the gate leaf so that the leaf could be leveled accurately when in

stalled in the slots . The pulleys, which were ball-bearing mounted, were

adjustable for both height and alignment so that they would be in line

with the hoisting cables and so that the two cables would subtend a min

imum angle where they were connected to the Hunter gage .

8. The 1 :60-scale model of a single l eaf was installed in an ex

isting glass -sided flume for visual study of flow patterns . ~is gate

leaf consisted of a block of wood equal in thickness and height to the

over-all dimensions of the gate leaf . The portions of the skinplate ex

tending beyond the upper and lower girders forming the gate lips were

fabricated of sheet metal. The model was one foot wide (60ft prototype)

and of uniform cross section; therefore it was not an exact reproduction

of a gate leaf but only of the cross section of the center portion of the

l eaf . This installation is shown on fig . 7.

Method of Operation - Downpull Tests

10. When a gate leaf was installed in the slots for testing it

was checked immediately for levelness and freedom from binding throughout

the range of operation. All tests were conducted with the gate leaves

closing and an initial downpull reading was taken either just as the

lower lip of the leaf came in contact with the nappe or with the leaf at

its highest position if the pool elevation was too high for the leaf to

clear the surface. Normally, downpull readings were taken at each 5-ft

interval of elevation thereafter except that an additional reading was

always taken at the point where the nappe just overtopped the leaf.

This was usually the position of maximum downpull and was caused by the

very thin nappe clinging to the edge of the top girder and falling on

the lower girders.

11. The openings at which bouncing occurred were noted and

operation was discontinued at those points. The term "bouncing" indi

cates rapid and destructive alternating vertical movement of the leaf

of up to 40 ft prototype. Frequently there was a tendency to bounce,

that is the leaf would bounce if initial oscillations were set up by

jiggling the supporting cables. Under certain flow conditions the down

pull readings fluctuated widely and rather rapidly at some particular

gate opening but the leaf could not be induced to bounce. In those

cases, maximum, minimum, and observed average readings were recorded.

Since it was very difficult to take these readings accurately, the data

recorded in such cases should be considered as approximate. The gate

leaves were always tested to the fully closed position except in those

cases where the weight of the leaf was not sufficient to cause complete

closure.

10

PART III: TESTS AND RESULTS

12. A series of 84 complete downpull tests was performed; the re

sults obtained are summarized in table 1. The program involved the

testing of a number of gate designs, operation of from one to three gate

bays, operation of individual as well as attached gate leaves, and opera

tion with a wide variety of headwater-tailwater combinations. Features

of the different designs are shown on plate 1. All of these tests were

performed with the air vents at the original elevations of 8, 21, 34,

and 47 ft.

13. Initial tests with gate leaves 3 and 4 in their normal posi

tions in bay 6 {see plates 2-17) revealed that, under certain river

stages, leaf 4 would bounce violently. Leaf 3 exhibited a tendency to

bounce at a tailwater of 40 ft and a headwater of 55 or 60 ft. The

magnitude of the cable stress induced by this bouncing was such as to

cause the small brass wire hooks, by which the cables were affixed to

the leaf, to straighten out. In order to avoid further damage to the

gate a model operator caught the leaf as soon as bouncing started. Under

these conditions it was impossible to measure the maximum downpull that

occurred; however, it is known that the downpull exceeded five times the

weight of the gate leaf at times. The degree of elasticity of the sus

pension seemed to have little effect since bouncing occurred even with

the spring scale removed from the system.

14. At this point testing of the 1:60-scale section model of the

outline of the 15-ft gate leaf was initiated so that flow patterns could

be observed. Violent flow conditions ensued with headwater and tail

water elevations comparable to those which had caused bouncing in the

1:36-scale model. The nappe just downstream from the gate oscillated

up and down rapidly, thereby creating an audible slapping sound. At

the same time vortices could be seen forming alternately at the upper

and lower lips of the gate leaf in resonance with the flapping action of

the nappe. A length of hollow glass tubing was held so that the lower

end was adjacent to the lower lip of the gate leaf. The water column in

this tube fluctuated with the same frequency as the formation of the

11

vortices. Air introduced under the nappe increased the fre~uency of vortex

formation and apparently reduced the amplitude but did not eliminate pres

sure fluctuations, thus indicating that modifications to the air vents

alone would not guarantee freedom from bouncing. The air vent size was

varied (see fig. 8) but no noticeable change in flow conditions resulted;

thus the original 15-in.-diameter vents were considered to be ade~uate for

all air demands. Honeycombing the skinplate with holes above the top

girder failed to prevent formation of the vortices. High-speed motion

pictures were taken which show the vortex formation clearly; one vor-

tex can be seen forming at the top lip of the gate leaf on fig. 7. 15. The phenomenon of alternate vortex formation at the sides

of a cylinder immersed in flowing water was first described by Strouhal*

in the formula:

where:

fD s = v

S = dimensionless "Strouhal number"

f freq_uency

D = diameter of cylinder

V velocity of fluid past cylinder.

This formula was derived from observations only. Some years later,

von Karman* made a theoretical analysis of the subject which led to the

development of a formula for the magnitude of the alternating force

associated with the vortex formation:

where:

FK =Karman force (normal to flow)

CK = Karman coefficient (approximately 1)

p = density of fluid

V = velocity of fluid past cylinder

A =projected area of obstacle (normal to flow).

* J. P. den Hartog, "Recent technical manifestations of von Karman's vortex wake," Proc., Nat. Acad. of Sc. of U.S.A., vol 40, No. 3, 1954•

12

Application of the latter formula to the case of the Old River vertical

lift gate results in an alternating force considerably less than the dry

weight of the gate except for the condition of maximum headwater

tailwater combination. Den Hartog* states that the Karman force is

greater for a cylinder that is vibrating at the Strouhal fre~uency than

for one that is at rest, and it is believed that this principle applied

in the bouncing of the gate. Apparently the alternating Karman force was

large enough to set the gate in motion, since the cable suspension was

somewhat elastic; and once motion had begun, the magnitude of the alter

nating force and the amplitude of the bounce each increased in a manner

of mutual excitation.

16. Rouse** states that the Strouhal number for a flat plate im

mersed in flowing water with the plane of the plate normal to the direc

tion of flow is approximately 1/7. Since the Old River gate installation

was analagous to this situation (see fig. 9), the Strouhal formula was

used to compute the theoretical vortex formation fre~uencies for gate

leaf heights of 15, 25, and 35 ft (see fig. 10). Actual observations of

the 1:60-scale model showed that the vortices were forming at the

frequencies shown by the dashed curves of fig. 10 for 15- and 25-ft leaf

heights. Since model operation was at Reynolds numbers for which the

Strouhal formula should apply, it is believed that external factors and

nonsymmetrical velocity distribution around the gate were responsible

for the rather wide divergence from theoretical frequencies.

17. Since no way had been found to eliminate the vortices in the

small-scale section rr.odel, the first revisions to be tried in the 1:36-

scale comprehensive model were directed toward reducing the alternating

force effect upon the gate leaf. Types 1-A and 1-B gates (see plate 1)

incorporated 1.5- and 3.0-ft extensions to the upper and lower lips of

the leaves but failed to eliminate bouncing as shown on plates 18-23.

When the leaf was reversed in the slots so that the skinplate was on the

downstream side, it either bounced as in the case of type 1-R or failed

to close of its own weight as with types 1-A-R and 1-B-R (see plates

24-31). A skinplate from the top lip to the back of the top girder

(type 2) did not eliminate bouncing (see plates 32-34).

18. The fact that the gate leaf bounce was being caused by cir

culation around the leaf led to the belief that if the leaf height were

increased, damping effects might be increased and bouncing eliminated.

Leaf 3, which was 19 ft high, was first tried in the No. 4 position but

the tendency to bounce persisted. The next step was to fasten leaves 3

and 4 together and to operate them as a single 34-ft-high leaf. This

arrangement eliminated bouncing throughout the range of operation and a

tendency to bounce occurred only at the 54-ft-pool and 40-ft-tailwater

combination with the three center bays in operation. The results of

this series of tests are shown on plates 35-60. All of these tests were

performed using gate leaves of the original design.

19. When installed in gate bay 9 in the high section of the weir,

gate leaf 3, which occupieu the bottom position, bounced at tailwater

elevations above 25 ft. Gate leaves 3 and 4 operating as a single 34-

ft-high leaf (installed in the positions of leaves 2 and 3, respectively)

eliminated bouncing just as they had done in bay 6. Since the gate will

be 38 ft high with leaves 2 and 3 fastened together, these test results

are on the safe side (see plates 61-80).

15

20. Throughout the tests just described the maximum downpull force

for most test conditions had been about 100,000 to 190,000 lb with two

gates leaves of original design joined together. A few additional tests

were performed to determine whether or not this force could be reduced

by extending the bottom lip or by placing a cover plate over the top

girder of the top gate leaf. Type 1-C incorporating the lower lip ex

tension and type 2-C which utilized a plate extending only as far down

stream as the edge of the girder did not reduce downpull but types 2-A

and 2-B with overhanging cover plates were quite effective. Since the

effect of the overhanging plates was to prevent the jet from falling

back in on the lower girders, and since this condition probably would

not occur in the prototype except in high winds, the value of the cover

plate is questionable (see plates 81-84).

21. The addition of cover plates caused the gate to bounce under

certain conditions for the 67-ft-pool and 40-ft-tailwater combination.

This led to the opinion that the gate of original design might also be

somewhat susceptible to bouncing under the same conditions. For this

reason the original test, the results of which are shown on plate 50,

was rerun and the results are shown on plate 85. It was found that the

gate would bounce at a 15-ft opening if it were allowed to stay in that

position for a sufficient length of time. Deaeration of the nappe caused

the bouncing to startj consequently the air vents, originally located at

el 8, 21, 34, and 47 ft, were relocated at el 28, 34, 40, and 47 ft so as

to be more effective, and the bouncing was eliminated for all designs and

stages with the two bottom leaves operating together.

22. A short series of tests was performed on the 1:60-scale sec

tion model to determine the maximum pressure differential between the

upstream and downstream sides of the gate and the maximum negative

pressures on a cover plate with a 6-in. overhang on the downstream side

of the gate. Details of the installation are shown on fig. 8. It was

found that the maximum differential between piezometers 1 and 2 for de

sign conditions was 38 ft of water. The maximum negative pressure read

ing on piezometer 3 was -2.0 ft of water and on piezometer 4, -1.3 ft.

These negative pressures were read at a head just low enough to prevent

the jet from springing free of the cover plate.

16

PART Dl: CONCLUSIONS

23. The proposed design of the vertical lift gates is entirely

satisfactory provided the two bottom gate leaves are fastened together

and are operated as one unit. The air vents in the three center bays

should be relocated at el 28, 34, 40, and 47 ft to insure elimination

of the tendency of the gate leaves to bounce. Under these conditions,

the maximum hoist load per bay will be about 370,000 lb.
