Particle size distributions of bed sediments along the thalweg of the Mississippi River, Cairo, Illinois, to Head of Passes, September 1989 : Potomology Program (P-1), report 7 by Carl F Nordin( Book )

2 editions published in 1992 in English and held by 143 WorldCat member libraries worldwide

Changes in Mississippi River bed material gradations between Cairo, IL, and head of Passes, LA, between 1932 and 1989 were determined. In September 1989, bed material samples were collected from the thalweg of the river along the 955-mile reach. In all, 504 samples were collected at 417 locations. Results were compared to a similar sampling program conducted in 1932. In general, the 1989 bed contained less coarse sand and gravel and less very fine sand than the 1932 lied. Upstream of the Old River Structure near river mile 300 the bed was generally finer in 1989 than in 1932. Downstream from river mile 300 the median grain size was about the same, but the distribution was more uniform, with less very fine sand

Practical riprap design by Stephen T Maynord( Book )

6 editions published in 1978 in English and held by 95 WorldCat member libraries worldwide

Determination of stable riprap size is a problem that has been studied extensively but not yet solved. Existing design methods are based on the shear stress exerted by the flowing water on the channel boundaries. The various methods available for computing the shear stress do not agree. Determination of the amount of shear stress a given size riprap can withstand depends upon which investigator's coefficient is used in the Shields' equation. The objective of this investigation was to develop a riprap design procedure based on known or easily calculated variables that properly describes riprap stability. Model tests or riprap stability were used in this investigation to insure that the proposed design procedure is applicable to the higher turbulence levels found in decelerating flow in open channels. Design curves for bottom riprap and side slope riprap in straight channels are presented. Tentative criteria for riprap in channel bends are discussed. (Author)

Jefferson Barracks Bridge : movable-bed model study by James E Foster( Book )

2 editions published in 1988 in English and held by 88 WorldCat member libraries worldwide

In July 1977, the Illinois Department of Transportation awarded a contract to construct piers for Interstate Highway 255 Bridge across the Mississippi River at mile 168.7. As of March 1979, the contractor had constructed a work trestle across Jefferson Barracks Slough and a work trestle from the island to a point past pier 10. The contractor also had constructed cofferdams for the construction of piers 5-10, 12, and 13. In the spring of 1979, the discharge in the river increased, and debris accumulated upstream of the work trestle. On 21 March 1979, the portion of the work trestle between cofferdams at piers 9 and 10 failed. It is not known exactly when the cofferdam at pier 10 failed, but it is assumed that it failed about the same time as the trestle between cofferdams at piers 9 and 10 failed. By 19 April 1979, the cofferdam at pier 9 and the portion of the work trestle between cofferdams at piers 8 and 9 had failed. This study was conducted to investigate the relationship of the existence of the work trestle, the cofferdams, and the accumulation of debris that occurred upstream of the work trestle to the riverbed movement that occurred before, during, and after the failure of the work trestle and cofferdams.

Old River low-sill control structure : dynamic hydraulic forces acting on the stilling basin, survey boat safety, and debris passage : hydraulic model investigation by Bobby P Fletcher( Book )

5 editions published in 1988 in English and held by 87 WorldCat member libraries worldwide

Tests were conducted in 1:36-scale section models of the high and low bays to develop guidance for rehabilitation of the existing stilling basin, to develop guidance for the safety of survey boats operating in the approach to the structure, and to evaluate characteristics of debris passage through the structure. The portion of the basin between the baffles and end still was protected with sloping modules constructed of steel and grout, and tests were conducted to determine the hydraulic forces acting on the modules. A flow spoiler design to reduce uplift forces on the modules and not increase the sliding and uplift forces on the modules and not increase the sliding and uplift forces acting on the stilling basin was also investigated. Survey boat safety tests indicated that a typical survey boat operating upstream of the gate bays should be safe with gate openings equal to or less than 30% of the head on the crest. Debris passage tests indicated that debris up to 35 ft long and 3.0 ft thick would pass through the structure with gate openings equal to or greater than about 30 -40% of the head on the crest
Lake Darling Spillway, Souris River, North Dakota : hydraulic model investigation by Deborah R Cooper( Book )

6 editions published in 1988 in English and held by 87 WorldCat member libraries worldwide

The concrete gravity ogee spillway for the Lake Darling Dam will contain five 22-ft-high by 43-ft-wide gate bays separated by 10-ft-wide pairs. Outlet works consisting of four sluices within the piers will discharge into the spillway stilling basin. A hydraulic-jump-type stilling basin will provide satisfactory dissipation of the spillway and sluice flows. A 1:36-scale model of the spillway, sluices, stilling basin, approach area, and exit channel was used to study the overall hydraulic performance of the structure. Tests indicated that flow conditions in the approach to the spillway with both uncontrolled and controlled flows were satisfactory for the full range of anticipated discharges. Eddies developed on either side of the stilling basin. Constricting the channel flare to a uniform width eliminated the eddies. The size and extent of stone protection required on the dam embankment, side slopes and bottom of the approach channel, and side slopes and bottom of the exit channel were determined by model investigations.

Evaluation of vertical motion sensors for potential application to heave correction in Corps hydrographic surveys by George C Downing( Book )

6 editions published in 1987 in English and held by 86 WorldCat member libraries worldwide

This report describes techniques and equipment that can help surveyors obtain the best practical vertical reference for hydrographic surveys in the face of adverse tide, river stage, and wave conditions. USAWES efforts involved evaluating a heave compensation system (HIPPY 120) and exploring the possibility of using Doppler equipment for measuring vertical boat motion. Some specific measurement techniques for monitoring vertical references for hydrographic surveys under given field conditions are addressed. Depth transducer draft, boat flotation plane, shore references and dynamic vertical motions of the boat hull are discussed. Vertical displacement measurement equipment using automatic electrooptical tracking systems, video-type optical tracking systems, laser leveling systems, and satellites is assessed and found to have potential for future consideration and application in improving survey accuracy. Evaluation of a heave compensation unit based on a pendulum-stabilized accelerometer platform (HIPPY 120) was attempted on a survey boat. Protracted difficulties with the system prevented a quantitative evaluation. These results lead to the conclusion that for this system to be successfully used during actual survey operations, there must be a higher-than-average level of technical skill among the personnel on the survey boat

Sweetwater River Channel Improvement Project, San Diego County, California : hydraulic model investigation by Herman O Turner( Book )

3 editions published in 1988 in English and held by 86 WorldCat member libraries worldwide

In the area of proposed improvement, the Sweetwater River is a poorly defined channel varying from 1,200 to 2,000 ft wide in a relatively broad floodplain. An entrenched trapezoidal channel with a base width of 320 ft has been excavated ending just upstream of a freeway bridge. This channel has a radius of 1,000 ft and turns approximately 80 deg in relation to the proposed channel alignment through the freeway bridge. A drop structure is to be located in the radius of the curve at the beginning of the project. A study of the proposed project was conducted using a fixed-bed constructed at a scale of 1:40 to study the effect of downstream waves and disturbances caused by the curvilinear flow conditions. The main objectives of the study were to obtain quantitative information on flow patterns, flow distribution, waves, and disturbances throughout the curved reach of channel, as well as to determine the effects of sediment buildup on water-surface elevations. The model study revealed that certain refinements are needed to the Sweetwater River project to eliminate potential problems. Keywords: Curved waterway channels; Curvilinear flow; Sediment wedge
Safe navigation speeds and clearance at lower sill, temporary Lock 52, Ohio River by Stephen T Maynord( Book )

5 editions published in 1987 in English and held by 86 WorldCat member libraries worldwide

This investigation has identified four possible mechanisms for producing tow squat, the vertical drop of the tow due to motion, measured from the still water level, in the temporary lock at Locks and Dam 52. Based on tests with tows either self-propelled or pulled with a towing apparatus, this investigation shows that squat for entering tows is determined by different parameters from those for exiting tows. The maximum squat for almost every self-propelled test (entering or exiting) was located at the stern of the towboat. For loaded tows entering the lock, the primary mechanism producing squat was propeller squat. Because tests involving entering tows using the towing apparatus produced very little squat for entering tows. For loaded tows exiting the lock, propeller squat is still an important mechanism for producing sqat. This importance was illustrated by the acceleration tests, during which all the tows approached the sill at the same speed. Squat increased for increased propeller speed. The towing tests show tow speed to be another significant factor in defining squat for existing loaded tows. It was not determined whether this squat was displacement or piston squat. Unloaded exiting tows also have the potential for enough squat to strike the lower sill when operating at high propeller and potential for enough squat to strike the lower sill when operating at high propeller and tow speed. It is likely that displacement, propeller, and moment squat all contribute to the total squat for unloaded exiting tows. The downstream gates for the emptying flume should remain open during tow entry/exit. Entry/exit speeds were higher with the values open. For equal tow speeds, squat is considerably less with the valves open
Lock design, bottom longitudinal filling and emptying system by Thomas E Murphy( Book )

5 editions published in 1980 in English and held by 85 WorldCat member libraries worldwide

This report presents and summarizes directions for design of bottom longitudinal filling and emptying systems for navigation locks. Even though additional refinements to the system are desirable, the bottom longitudinal filling and emptying system unquestionably is the best system for intermediate- and high-lift locks used to date by the Corps of Engineers. It not only is superior when operated as planned but also is inherently safer than other systems in that it is not sensitive to faulty operation of the valves
Old River overbank structure outlet modifications : hydraulic model investigation by Ronald R Copeland( Book )

4 editions published in 1980 in English and held by 84 WorldCat member libraries worldwide

Six different outlet modification designs for the Old River Overbank Control Structure were evaluated. Model tests were conducted on five of the designs and design variations. A 1:24-scale section model was used to simulate discharges up to 550,000 cfs. Type 5 outlet modification design, utilizing gabions placed parallel to the flow on a 1V on 10H slope, was deemed the best of the six designs tested. Recommendations were also made to increase gabion effectiveness by improved construction and placement methods
Prototype evaluation of sluiceway aeration system, Libby Dam, Kootenai River, Montana by Richard G McGee( Book )

5 editions published in 1984 in English and held by 79 WorldCat member libraries worldwide

Tests were conducted to make a comprehensive prototype evaluation of the postmodification (i.e., aerator installation and air vent streamlining) operating conditions of the project. Prototype measurements included air vent discharges, center sluice aerator slot pressures, and invert pressures acting along the center line of the center sluice. Pressure drops from the atmosphere to the right and center sluice gate chambers were measured along with the pressure acting on the modified wall separating the center sluice gate chamber from the lower service gallery. In addition, vertical, transverse, and longitudinal structure accelerations were measured in the vicinity of the center sluice gate and on the sluice emergency gate during an emergency gate lowering operation
