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( )

2 editions published in 1992 in English and held by 363 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

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 105 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 104 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.

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)
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 95 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

Type 19 flood insurance study : tsunami predictions for southern California by James R Houston( Book )

3 editions published in 1980 in English and held by 90 WorldCat member libraries worldwide

Calculations of shoreline elevations due to tsunamis of distant origin were made for the southern California region. Elevations were determined that were expected to be equaled or exceeded on the average of once per 100 or once per 500 yr. In addition, exceedance frequency distributions for arbitrary frequencies of occurrence were presented. Historical data of tsunami activity in distant generation regions were used in the investigation in conjunction with numerical models that generated tsunamis and propagated them across the deep-ocean and nearshore region. The combined effects of the astronomical tides and tsunamis were incorporated in the analysis. Numerical simulations of the 1964 Alaskan tsunami in southern California were performed and comparisons with historical tide gage recordings were presented. Tsunami elevation predictions based upon the methods presented in the investigation were shown to be in good agreement with predictions based solely upon historical data of tsunami activity (at the limited number of locations in southern California with sufficient historical data to allow reasonable predictions to be made)
Evaluation of vertical motion sensors for potential application to heave correction in Corps hydrographic surveys by George C Downing( Book )

7 editions published in 1987 in English and held by 90 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
Jefferson Barracks Bridge : movable-bed model study by James E Foster( Book )

2 editions published in 1988 in English and held by 90 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.
