Navigation conditions at Lock and Dam 53, Ohio River, Kentucky and Illinois : hydraulic model investigation by Louis J Shows( Book )

20 editions published in 1979 in English and held by 106 WorldCat member libraries worldwide

This study is concerned with navigation conditions in the upper approach to a temporary 110- by 1200-ft lock under construction at the existing Lock and Dam 53 on the Ohio River. It became apparent during construction that the intensity of the crosscurrents in the approach to the existing lock would be increased with the temporary lock making navigation conditions extremely difficult and hazardous. The study was undertaken to determine the conditions that would develop with the structure as planned and to develop modifications required to provide satisfactory navigation. In order to provide results before construction was completed on the original plan, a semifixed-bed model utilizing existing facilities was used for the study. The model reproduced to an undistorted scale of 1:120 the dam, upper portions of the locks, and about 2 miles of the river upstream. Results of the investigation indicated the hazardous condition that could be expected with the structures as planned. Satisfactory navigation conditions could be developed with the temporary lock by extending the upper guard wall and providing sufficient ports in the wall to pass most of the flow intercepted by the wall.

Navigation conditions at Aliceville Lock and Dam, Mississippi and Alabama, Tombigbee River : hydraulic model investigation : final report by Louis J Shows( Book )

12 editions published between 1977 and 1978 in English and held by 93 WorldCat member libraries worldwide

Aliceville Lock and Dam will be the second navigation structure proposed for the development of navigation on the Tennessee-Tombigbee Waterway. The lock will be along the left bank of the Tombigbee River about 333 miles above the mouth of the Mobile River, which is at the foot of Government Street in Mobile, Alabama, or approximately 67 miles above the proposed Gainesville Lock and Dam. The structures will include one lock with clear chamber dimensions of 110 by 600 ft and a dam consisting of a gated spillway and a fixed-crest overflow weir designed to maintain during low flows a minimum upper pool at el 136.0 extending upstream about 32 miles to the proposed Columbus Lock and Dam. Results of the investigation revealed the following: (a) satisfactory navigation conditions in the upper lock approach could be developed with modification of the excavation along the left bank of the approach channel and excavation of the right bank in the bend near the upper end of the approach channel; (b) navigation conditions in the lower lock approach could be improved considerably with a dike angled riverward along the right side of the approach channel; (c) two-way traffic in the second bend upstream of the upper lock approach would be difficult and hazardous during the higher flows; (d) recommended changes to the original plan would have little effect on water-surface elevations in the reach or on conditions that could be expected during construction of the lock and dam
Navigation conditions at McAlpine Locks and Dam, Ohio River : Hydraulic model investigation by Louis J Shows( Book )

15 editions published between 1966 and 1981 in English and held by 93 WorldCat member libraries worldwide

Model investigations of McAlpine Locks and Dam (formerly Locks and Dam No. 41) was concerned with the reconstruction and modernization of the existing locks and dam on the Ohio River at Louisville, Kentucky. The modernization plan included the construction of a new 110- by 1200-ft lock northwest of the existing 56- by 360-ft lock, modernization of an existing 110- by 600-ft lock, widening of the upper entrance canal, and reconstruction of the existing dam. An undistorted model, scale 1:120, reproducing approximately 6 miles of the Ohio River, the locks and dam, approach canal, hydroplant, and other structures that affect flow conditions, was used for the investigation. Results of the study were used to develop detail modifications in the various elements of the selected plan and in the development of a rating curve for the dam. (Author)

Summary report : model-prototype comparison study of dike systems, Mississippi River : potamology investigations by John J Franco( Book )

10 editions published in 1982 in English and held by 86 WorldCat member libraries worldwide

Movable-bed model studies were conducted of seven of the most complex and troublesome reaches of the Mississippi River to obtain some quick general indications of the effectiveness of plans proposed for the improvement and stabilization of those reaches. Because of the limited time available, the studies were conducted in an existing facility with little or no adjustment of the models and in some cases without a base test. Because of the limited size and shape of the facility, only a relatively short reach of the river including the problem could be reproduced in each model with little or no overbank areas. The horizontal scale varied with each reach depending on its size and shape and were much smaller with a higher distortion of the linear scales than was considered desirable for studies of this type. An analysis of the model results compared with developments in the river based on an evaluation of considerable prototype data indicated that the types of models used predicted, at least qualitatively, most of the principal trends that actually occurred in the river with the plans tested. The degree of accuracy of the models varied and depended to a considerable extent on the model adjustment, characteristics of the reach, flow conditions, and similarity between plan tested and actual construction. The analysis of model and prototype data permitted an evaluation of the performance of various types of dikes and dike systems and some of the principles involved in the developments within alluvial streams
Guidelines for the design, adjustment, and operation of models for the study of river sedimentation problems by John J Franco( Book )

7 editions published in 1978 in English and held by 85 WorldCat member libraries worldwide

Streams in which sedimentation problems are encountered are extremely complex and developments within these streams depend on many factors, most of which are interrelated. Few basic principles are available to the design engineer in the solution of problems concerned with channel improvement and stabilization, and many of the plans and types of structures used have been based on experience and general judgment. Because of the difficulties and costs involved in experimenting with the actual river and the impracticality of comparing the effectiveness of various concepts and designs under the same conditions, the development of new principles and procedures or the optimum solution to many problems have to depend to a considerable extent on river model investigations coordinated with results in the field. This report is a general guide for laboratory engineers and technicians concerned with model invesitgations of sedimentation problems in alluvial streams. The report describes many of the principles and procedures used in the design, adjustment, and operation of movable-bed models and the factors to be considered in the development of improvement plans and in the interpretation of model results. Appendices cover the characteristics of model bed material, slopes required, and check list for model design and operation

Shoaling conditions in Sawyer Bend and lower entrance to Chain of Rocks Canal, Mississippi River : hydraulic model investigation : final report by James E Foster( Book )

10 editions published in 1978 in English and held by 78 WorldCat member libraries worldwide

This investigation was concerned with the development of an adequate channel and access to the docking facilities along the right bank in Sawyer Bend and the reduction or elimination of shoaling in the lower entrance to the Chain of Rocks Canal. The alignment of the channel upstream of Mosenthien Island and the movement of sediment from the Missouri River along the right bank caused an increase in flow through the chute channel to the left of Mosenthien Island and shoaling in the channel along the industrial docking facilities in Sawyer Bend. Shoaling in the lower entrance to the canal during low flows has created a serious problem because of the amount of dredging required and the lack of suitable disposal areas. The purpose of the model study was to develop plans that would provide a satisfactory channel in Sawyer Bend and reduce or eliminate the need for dredging in the lower entrance and approach to the Chain of Rocks Canal. A movable-bed model, constructed to scales of 1:250 horizontally and 1:100 vertically, reproduced the Mississippi River and adjacent overbank areas between miles 191.0 and 180.5
Navigation conditions, Suck Bend Reach, Chattahoochee River, Alabama and Georgia : hydraulic model investigation by Bertrand K Melton( Book )

6 editions published in 1978 in English and held by 78 WorldCat member libraries worldwide

The Suck Bend Reach of the Chattahoochee River is in the upper end of Columbia Lock and Dam Pool about 1.5 miles downstream of the Walter F. George Lock and Dam. Suck Bend is essentially two adjacent and alternate bends in the form of a relatively flat 'S' curve. Shoaling that occurs in the bend during flood flows and at times during powerhouse operation has been a problem for navigation when there is little or no flow from upstream. A movable-bed model reproducing about 1.5 miles of the Chattahoochee River to an undistorted scale of 1:72, model-to-prototype, was used to develop plans that would eliminate or reduce shoaling sufficiently to permit uninterrupted navigation and to improve navigation conditions for larger tows through the bend and in the approach to the proposed State Highway 10 bridge
Navigation conditions in Alexandria Reach, Red River Navigation Project, Louisiana : hydraulic model investigation by Louis J Shows( Book )

7 editions published in 1978 in English and held by 75 WorldCat member libraries worldwide

Alexandria Reach is a section of the Red River approximately 87.3 miles upstream of the junction of the Red and Mississippi Rivers. The reach is included in the Red River Navigation Project and will be about 14 miles upstream of Lock and Dam No. 2. There are five bridges in the reach within a distance of less than 2 miles. A fixed-bed model reproducing about 3.5 miles of the river in the vicinity of Alexandria, Louisiana, to an undistorted scale of 1:100 was used to determine navigation conditions through the reach and to develop modifications required to eliminate any adverse conditions indicated. The model investigation was concerned principally with navigation conditions approaching and through the bridges. The high-velocity currents with the water-surface elevations anticipated in the reach indicate that some scouring of the channel bed and changes in channel cross section can be expected with the completed project. Navigation through the reach will tend to be hazardous because of the limited widths of spans divided by a center pier, alignment of the channel and bridge spans, and short distance between some of the spans. Satisfactory navigation conditions would require the use of tows with sufficient power and maneuverability to maintain control and alignment and widths of tows limited to 35 ft
Channel widths in bends and straight reaches between bends for push towing : hydraulic model investigation by Louis J Shows( Book )

6 editions published in 1982 in English and held by 75 WorldCat member libraries worldwide

This investigation was concerned with the development of parameters that could be used as a guide in the layout and design of shallow-draft waterways, particularly bends and straight reaches between bends. Results are based largely on model studies using different linear scales and some limited prototype tests. In negotiating a bend or making a turn, tows occupy a greater channel width than in straight reaches. The width of channel required depends on the deflection or drift angle which varies with the size of two, radius of the bend or tunr, length of the bend up to about 90 deg, alignment and velocity of currents, weather conditions, direction of travel (upstream or downstream) draft of two with respect to channel depth, alignment and location of the tow when entering the bend, and maneuverability of the tow. If the deflection angle assumed by a tow in negotiating a bend is known, the width of channel required can be computed using one of the equations from this study. Results include curves showing the deflection angle assumed by tows of various sizes in bends of different curvatures with and without currents. Also covered are bends consisting of compound curves, bends with irregular bank lines, and lengths of straight reaches required between alternate bends

Navigation conditions at the upstream approach to Lock and Dam No. 3, Mississippi River : hydraulic model investigation by Louis J Shows( Book )

5 editions published in 1979 in English and held by 72 WorldCat member libraries worldwide

The Lock and Dam No. 3 navigation structure is located on the upper Mississipi River at about mile 797 above the mouth of the Ohio River and 44.2 miles above Lock and Dam No. 4. The structure is designed to maintain a minimum upper pool during low flows extending 18.3 miles upstream to Lock and Dam No. 2 on the Mississippi River and approximately 52 miles up the St. Croix River. The section of pool extending into the upper Mississippi River provides water access to Minneapolis and St. Paul, Minnesota. The four-gated spillway section is located in the main river channel, and the lock with clear chamber dimensions of 110 by 600 ft and the upper lock gates for a proposed second lock are located in a bypass canal on the right overbank. A fixed-bed model reproducing about 2 miles of the Mississippi River channel, upstream lock approach, a portion of Sturgeon Lake, and adjacent overbank areas to an undistorted scale of 1:120 was used to determine the adequacy of the proposed plan and to develop modifications required to eliminate any adverse conditions indicated. Results of the investigation revealed that satisfactory navigation conditions in the upper lock approach could be developed by replacement of the guide wall with a guard wall with some excavation along the right bank or with a rock dike extending upstream from the right abutment wall of the dam. Ice gaps or openings would be required to reduce the accumulation of ice in the lock approach with either of the plans

Webbers Falls Lock and Dam, Arkansas River navigation project : hydraulic model investigation by John J Franco( Book )

13 editions published in 1969 in English and held by 66 WorldCat member libraries worldwide

Webbers Falls Lock and Dam will comprise a nonnavigable dam of 12 gated spillway bays, a 110- by 600-ft lock on the left bank, and a three-unit powerhouse with a discharge capacity of 35,500 cfs on the right bank. A 1:120-scale fixed-bed model was used to determine flood stages at the dam, navigation conditions in the lock approaches, tendency for sediment deposition in the lower lock approach, and magnitude of surges generated in the upper lock approach canal by lock filling, and to develop modifications required to provide satisfactory conditions. Modifications to the original design required to produce satisfactory navigation conditions in the approaches to the lock were developed and flow conditions through the spillway were improved.

Navigation conditions at Ozark Lock and Dam, Arkansas River : hydraulic model investigation by John J Franco( Book )

19 editions published between 1968 and 1972 in English and held by 65 WorldCat member libraries worldwide

The Little Rock Reach is a comparatively straight and relatively narrow reach of the Arkansas River located between Little Rock and North Little Rock, Ark. Six bridges are located in this reach of the river iwthin a distance of about 1.4 miles in the vicinity of mile 165. The model investigation was primarily concerned with navigation conditions in the reach particularly as affected by the bridges and with the development of plans as required to provide satisfactory navigation for both upbound and downbound traffic. An undistorted, fixed-bed, 1:100-scale model reproduced about 3 miles of the Arkansas River and adjacent overbank areas and the six bridges located in the reach. (Author)
Development of navigation with locks and dams by John J Franco( Book )

5 editions published in 1976 in English and held by 56 WorldCat member libraries worldwide

The need for locks and dams for the development of navigation on some streams and the problems that could be encountered are discussed in this report. Satisfactory navigation conditions depend on the site selected, characteristics of the stream, orientation and arrangement of the structure and related facilities, and type of traffic anticipated. Tows approaching the locks could be affected by adverse currents that could be hazardous or cause delays. The lock arrangement should consider the currents to be caused by the completed structure and the effects of these currents on the movement of tows. Model studies can be invaluable in determining the adequacy of a proposed structure and modifications required to eliminate any undesirable conditions. New concepts in lock arrangements should be considered to improve safety and efficiency. Shoaling in the lock approaches can present serious problems but can be eliminated or minimized with special structures. Cofferdam plans should consider maintenance of navigation during construction and the effect of scour on its stability. Deflectors can be used to move the scour area away from the main cofferdam.

Development of navigation at lock and dam no. 17, Arkansas River project; hydraulic model investigation by John J Franco( Book )

7 editions published in 1970 in English and held by 49 WorldCat member libraries worldwide

Lock and Dam No. 17 will comprise a nonnavigable gated dam with three 61-ft-wide by 27-ft-high tainter gates 9.8 miles above the confluence of the Arkansas and Verdigris Rivers, and a 110- by 600-ft lock located about 0.6 mile east in an excavated, slack-water navigation canal. Two 1:120-scale fixed-bed models, reproducing the upper and lower reaches of the river channel and the slack-water navigation canal, were used to study navigation conditions at the upstream and downstream entrances to the navigation canal, and to determine flow conditions that could be expected near the entrances to the slack-water canal and through existing and proposed bridges and the modifications required to produce satisfactory navigation conditions through the reach.
