South jetty stability study, Masonboro Inlet, North Carolina : hydraulic model investigation by Robert D Carver( Book )

8 editions published in 1978 in English and held by 86 WorldCat member libraries worldwide

Hydraulic model flume tests were conduced to investigate the stability response of a jetty cross section proposed for the South Jetty, Masonboro Inlet, North Carolina. The original design (Plan 1) was not stable, and three additional designs were tested in an effort to find a satisfactory solution. All designs tested consist of one layer of armor stone subjected to breaking wave conditions. None of the designs were completely stable for all the designated storm conditions, and sufficient funds were not available to further the investigation. Based on the tests conducted, results show that all the designs were stable for storm conditions at the +8.5 ft mllw swl, but none of the designs were stable for storm conditions at the +12.5 ft mllw swl. Thus, whether the designs tested meet the no-damage criteria depends upon the selection of the design storm condition. (Author)
Rubble-mound breakwater stability and wave-attenuation tests, Port Ontario Harbor, New York : hydraulic model investigation : final report by Robert D Carver( Book )

11 editions published in 1981 in English and held by 80 WorldCat member libraries worldwide

An undistorted-scale hydraulic model study was conducted to investigate the armor stability and wave-transmission design of three breakwater cross sections for Port Ontario Harbor, New York. Plan 1 was constructed to a crown elevation of +10 ft lwd and used armor slopes of IV on 2H and 1V on 1.5H lake-side and harbor side, respectively. A crown width of 16 ft, equivalent to three armor-stone diameters, was used and the slopes and crown were armored with two thicknesses of 7.8-ton stone. Plan 1A was the same as Plan 1 except that the crown elevation was lowered to +9 ft lwd. Plan 2 was similar to Plan 1 except that the armor weight was reduced to 5.3 tons and the crown width was narrowed to 14 ft. Based on results of model tests, it was concluded that Plans 1 and 2 meet the designated wave-transmission criteria of significant transmitted wave height greater than or equal to 3.0 ft and are stable designs for the maximum breaking wave heights that can be produced in the model for 7- to 11-sec waves at swl's of +1.0 and +4.6 ft lwd. Plan 1 exhibited the best stability response of all three plans investigated. Maximum significant transmitted wave heights were 2.5, 3.0 and 2.4 ft for Plans 1, 1A, and 2, respectively. (Author)
Dolos armor units used on rubble-mound breakwater trunks subjected to nonbreaking waves with no overtopping : final report by Robert D Carver( Book )

9 editions published between 1976 and 1978 in English and held by 76 WorldCat member libraries worldwide

This investigation describes a portion of a research effort to provide fundamental data for the design of rubble-mound breakwaters. This report addresses the use of dolos armor on breakwater trunks subjected to nonbreaking waves and with no overtopping. The majority of the tests reported herein were designed to determine the stability coefficient, K, and runup and rundown values for the above conditions. Additional limited tests were conducted to show what effects (1) varying the first underlayer stone material from 1/5 to 1/20 of the armor weight (Wr) would have on armor stability, wave runup, and wave rundown; (2) placing the dolosse in selected geometric patterns would have on stability; and (3) reducing the number of dolosse used in the cover layer would have on stability
Effects of first underlayer weight on the stability of stone-armored rubble-mound breakwater trunks subjected to nonbreaking waves with no overtopping : hydraulic model investigation by Robert D Carver( Book )

8 editions published in 1980 in English and held by 75 WorldCat member libraries worldwide

Hydraulic model tests were conducted to determine the stability response of stone-armored breakwaters for a selected range of first underlayer weights. It was concluded that for the range of test conditions considered: (a) variations in first-underlayer stone weights (w sub 1) from (w sub r)/5 to (w sub r/20 do not have a significant effect on armor stability; (b) armor stability will not be significantly influenced by relative depth (d/L) or wave steepness (H/L); and (c) wave runup and rundown are not significantly affected by variation in first-underlayer stone weights (w sub 1) in the range (w sub r)/20 <or = w sub 1 <or = (w sub r)/5.

Floating breakwater wave-attenuation tests for East Bay Marina, Olympia Harbor, Washington : hydraulic model investigation by Robert D Carver( Book )

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

An undistorted-scale hydraulic model study was conducted. Initially, two-dimensional (2-D) flume tests were employed to determine the wave-attenuating properties of four floating breakwater cross sections. Based on results of the 2-D tests and relative costs of the structures, the best plan was selected for three-dimensional (3-D) testing. The 3-D tests investigated the combined effects of angular wave attack, structure alignment, wave transmission, and wave diffraction around the exposed end of the breakwater system. The 2-D tests showed the transmission coefficient (Ct) to be strongly dependent on relative structure width (W/L) and weakly dependent on wave steepness (H/L). Results of the 3-D tests showed that maximum wave-height attenuation was achieved when incident wave crests were at a 15-degree angle relative to the center line of the breakwater. Also, 3-D test data showed that a large decrease in the water depth (from 25 ft to 10 ft) only produced a slight decrease in transmitted wave heights. (Author)
Breakwater rehabilitation study, Crescent City Harbor, California : coastal model investigation by R. Clay Baumgartner( Book )

11 editions published in 1985 in English and held by 68 WorldCat member libraries worldwide

An undistorted scale hydraulic model study was conducted to develop an adequate repair plan for a section of the Crescent City breakwater which as armored with dolosse. The damaged area was to be repaired with 42-ton dolos. It was desired to quantify the number of armor units required, the optimum slope on which to place the dolosse, overall constructability, and methods of stabilizing the transition areas. Based on results of model tests, a combination of trenching and buttressing with 25-ton armor stone is a constructable method of stabilizing the transition area
King Harbor, Redondo Beach, California, breakwater stability study : hydraulic model investigation by Ernest R Smith( Book )

5 editions published in 1990 in English and held by 65 WorldCat member libraries worldwide

A hydraulic model investigation of proposed breakwater modifications to King Harbor, Redondo Beach, California, was conducted at a geometrically undistorted scale of 1:35, model to prototype. Five breakwater cross sections were each subjected to 15 design wave and water-level conditions. Plans 1 through 3 consisted of variations of armor unit size on the rehabilitation sections. A transition layer of small stones was included in Plans 4 and 5 to reduce wave transmission. Data collected were displaced stones, qualitative overtopping observations, and wave transmission. Plan 5 gave the best combination of stability and reduction of wave transmission. Keywords: Breakwaters; Hydraulic models; Overtopping; Stability; Wave transmission. (jhd)
Use of site-specific model data for general breakwater design by Robert D Carver( Book )

7 editions published in 1992 in English and held by 64 WorldCat member libraries worldwide

The purpose of this investigation was to obtain a better understanding of why significant variations in the stability coefficient occur. Specifically, it was hoped that functional relationships could be developed between the stability coefficient and such variables as wave height, wave period, and water depth. These functional relationships would then be used as input to a n improved procedure for obtaining minimum armor unit weights required for hydraulic stability. Also, it was hoped that a link could be developed between breaking and nonbreaking wave test results. Based on results of model tests described herein, in which tetrapod, tribar, dolos, and stone armor are used on breakwater trunks and heads, it is concluded that test results are very significant in that they show tetrapod, tribar, dolos, and stone stability to be dependent on the combined effects of wave height, wave period, and water depth with minimum stability occurring at the lower values of d/L and higher values of H/d, i.e., longer wave periods in shallower water. An improved procedure for determining minimum armor unit weights was developed
Investigation of random variations in stability response of stone-armored, rubble-mound breakwaters by Robert D Carver( Book )

6 editions published in 1991 in English and held by 63 WorldCat member libraries worldwide

The purpose of this investigation was to obtain a better understanding of variations in the stability response of stone armor when used on breakwater trunks. More specifically, the goal was to quantify the random variations that may occur from one test to another. Based on results of model tests described herein, it was determined that breakwater stability may be greatly affected by random variations in testing; thus, repeat testing is a must. Also, test results clearly show the influence of wave period with the lower stabilities occurring at the lower values of d/L, i.e., longer wave periods in shallower water
Investigation of wave grouping effects on the stability of stone-armored, rubble-mound breakwaters by Robert D Carver( Book )

7 editions published in 1994 in English and Undetermined and held by 62 WorldCat member libraries worldwide

High sea waves tend to appear in groups rather than individually. Because of the nature of wave grouping, it appears that it may be an important influence on the stability of rubble-mound structures. The research documented in this report was conducted to obtain a better understanding of the effects of wave grouping on the stability of stone armor when used on breakwater trunks. Results of this study show stability to be influenced by wave period, spectral width, and wave grouping intensity. Levels of wave grouping tested herein are achievable at some, but not all, prototype locations; therefore, results should be applied on a case-by-case basis.

Stability of rubble-mound breakwater Lahaina Harbor, Hawaii : hydraulic model investigtion by Robert D Carver( Book )

5 editions published between 1976 and 1981 in English and held by 61 WorldCat member libraries worldwide

A hydraulic model study was conducted to investigate the adequacy of two breakwater sections proposed for Lahaina Harbor, Hawaii. The purpose of the study was to determine the stability of the structure when attacked by the largest waves which may occur in the area, the amount of wave overtopping occurring for the most severe wave condition, and the magnitude of transmitted wave heights associated with a selected range of incident wave conditions. All tests were conducted in a 5-ft-wide, 4-ft-deep, and 119-ft-long concrete wave flume at an undistorted linear scale of 1:22, model to prototype. It was concluded that both proposed breakwater sections will maintain their structural integrity, meet the nonovertopping criteria, and prevent excessive wave energy transmission through the breakwater
Rubble-mound breakwater wave-attenuation and stability tests, Olcott Harbor, New York : coastal model investigation by Robert D Carver( Book )

7 editions published in 1991 in English and held by 61 WorldCat member libraries worldwide

A 1:20-scale experimental model investigation was conducted to investigate the wave transmission response of a breakwater proposed for Olcott Harbor, New York. A check of the structure's stability showed the proposed section to be conservatively stable. Therefore, an alternate plan also was investigated in an attempt to reduce construction costs for the breakwater. Based on model tests results, it was concluded that: (a) Both plans tested are stable designs for the maximum wave heights that can be expected to occur (6- to 10-sec waves at still-water levels of +4.3 and +5.1 ft low-water datum). (b) Maximum transmitted wave heights were 0.9 and 1.5 ft for Plans 1 and 1A, respectively
Stability of stone- and dolos-armored, rubble-mound breakwater heads subjected to nonbreaking waves with no overtopping by Robert D Carver( Book )

6 editions published in 1987 in English and held by 60 WorldCat member libraries worldwide

The purpose of the investigation herein was to obtain design information for stone and dolos armor used on breakwater heads and subjected to nonbreaking waves. More specifically, it was desired to determine the minimum weight of individual armor units (with given specific weights) required for stability as a function of (a) Type of armor unit; (b) Sea-side slope of the structure; (c) Angle of wave attack; (d) Wave period; (e) Wave height; Based on tests and results described herein, in which stone and dolos armor are used on conical breakwater heads and subjected to nonbreaking waves with angles of wave attack of 0, 45, 90, and 135 deg, it is concluded that: (a) The longer wave periods (2.00 and 2.75 sec) generally produce the lower stabilities; (b) Angles of wave attack of 45 and 90 deg are the most critical; (c) Flattening the slope from 1V on 1.5H to 1V on 2H does not improve stability of the stone armor
Revetment stability tests for Sargent Beach, Texas( Book )

6 editions published in 1993 in English and held by 59 WorldCat member libraries worldwide

The objective of this study was to investigate, via a two-dimensional (2-D) coastal model, alternate designs for the proposed revetment. Tests were conducted at a geometrically undistorted scale of 1:24, model to prototype. Based on test results, it was concluded that: (1) Four- to six-ton armor stone is stable for the maximum wave heights that can be expected to occur for 8- and 10-sec waves at still-water levels (swl's) of +4.0 to +14.0 ft mean low tide (mlt) with assumed scour depths of -3.6 and -8.6 ft mlt. (2) Stability of the original concrete blocks, which were 6.0 ft by 5.5 ft by 2.5 ft and had 0 percent porosity, was only marginally acceptable for the maximum wave heights that can be expected to occur for 8- and 10-sec waves at swl's of +4.0 to +14.0 ft mlt with an assumed scour depth of -3.6 ft mlt. (3) Several modified block plans were tested and it was determined that the optimum block size was 5.75 ft by 5.75 ft by 2.5 ft. These blocks, weighing 6 tons and having a porosity of 4 percent, should prove stable for the maximum wave heights that can be expected to occur for 8- to 10-sec waves at swl's of +4.0 to +14.0 ft mlt with an assumed scour depth of -10 ft mlt.

Seawall and revetment stability study, Cape Hatteras Lighthouse, North Carolina by Peter J Grace( Book )

6 editions published in 1985 in English and held by 58 WorldCat member libraries worldwide

It is anticipated that erosion and gradual shoreline retreat will eventually diminish the beach fronting the Cape Hatteras Lighthouse. The US Army Engineer District, Wilmington, (SAW), is proving design expertise to NPS for the development of coastal protection works to safeguard the lighthouse. The plan of protection selected by NPS consists of encircling the lighthouse with a wave-reflecting seawall fronted by a stone revetment. The model study was conducted to determine the adequacy of the proposed seawall and revetment design and, if necessary, to develop alternate designs from which an optimum plan for stability and economy could be determined. The specific purposes of this investigation were to determine: a) The most severe wave conditions relative to stability of the seawall and stone revetment within the limits of still-water levels (sw1's) and wave periods that could be expected to occur in the area of the Cape Hatteras Lighthouse, b) The stability and optimum stone size of the rubble stone revetment under worst breaking wave conditions, c) The distribution of wave forces on the gravity seawall so that it could be designed to withstand their resultant forces and ensure stability against overturning and sliding, d) A seawall curvature that would prevent overtopping and minimize the resultant wave forces on the seawall itself; and e) The combined stability of the seawall and revetment resulting from the hydraulic interaction of the two components.

Sloping float breakwater study, Oregon Inlet, North Carolina : Coastal model investigation by Robert D Carver( Book )

6 editions published in 1987 in English and held by 58 WorldCat member libraries worldwide

Two-dimensional (2-D) and three dimensional (3-D) hydraulic model investigations were conducted at an undistorted linear scale of 1:25 (model to prototype) to acquire data on transmitted wave heights, mooring line forces, intermodule connector forces, bottom impact velocities, and barge angularities as a function of wave climate. These data were needed as input to optimize the design of the sloping float breakwater (SFB) concept whose function would be to protect floating dredges being used for sand bypassing at Oregon Inlet, N.C. The 2-D test indicated that for the 89.6- and 118.4-ft SFB's (a) the transmission response of both structures is strongly dependent on wave period; (b) increasing the water depth significantly decreases the wave-attenuating capabilities of both structures; (c) for most wave conditions, mooring forces are similar for both SFB lengths and tend to increase with increasing depth; and (d) peak flow velocities under the structure are generally higher for the longer SFB. The 3-D tests revealed that the existing barge connector concept would be subjected to extremely high forces during impact on a rigid bottom. A softer seafloor condition greatly reduced the connector forces, but since a soft bottom condition could not be guaranteed at all prototype sites, it was determined that the design of the existing connector system for highly rigid bottom-impact forces was not economically feasible. A connector system design that is isolated from these highly rigid bottom-impact forces is feasible, but needs further indepth study. (Author)
Stability of stone- and dolos-armored rubble-mound breakwater heads subjected to breaking and nonbreaking waves with no overtopping by Robert D Carver( Book )

4 editions published in 1989 in English and held by 57 WorldCat member libraries worldwide

The purpose of the model investigation reported herein was to obtain design information for stone and dolos armor used on breakwater heads and subjected to breaking waves. More specifically, it was desired to determine the minimum weight of individual armor units (with given specific weights) required for stability as a function of sea-side slope of the structure, angle of wave attack, wave period, and wave height
Stability response of stone- and dolos-armored, rubble-mound breakwater trunks subjected to spectral waves by Robert D Carver( Book )

6 editions published in 1989 in English and held by 56 WorldCat member libraries worldwide

The purpose of this model investigation was to obtain design information for stone and dolos armor used on breakwater trunks and subjected to selected spectral wave conditions. More specifically, it was desired to determine the required weight of individual armor units (with given specific weights) needed for stability as a function of armor type, wave height and period, and sea-side slope of the breakwater. Based on test results, it was conducted that: 1) Stability of both armor types is influenced by wave height, wave period, breakwater slope, and, to a lesser extent, water depth. 2) A new energy based stability number which correlates strongly with the relative depth was developed. 3) Stone stability was more strongly influenced by changes in breakwater slope than was dolos stability, and 5) Dolos test results showed more variability, i.e., were less repeatable than the stone stability tests.

Waianae small-boat harbor, Oahu, Hawaii, design for wave protection : hydraulic model investigation by Robert R Bottin( Book )

6 editions published in 1976 in English and held by 54 WorldCat member libraries worldwide

A 1:50-scale (undistorted) hydraulic model, reproducing approximately 1.4 miles of shoreline along the proposed Waianae Small-Boat Harbor site (beginning at Kaneilio Point and extending northwesterly), the surrounding reef, and sufficient offshore area to permit generation of the required test waves, was used to investigate the arrangement and design of proposed harbor configurations with respect to wave action. The basic harbor configuration consisted of (a) an outer breakwater, (b) a stub breakwater, (c) an entrance channel, turning basin, and main access channel, and (d) revetted fill areas in the harbor interior. Variations to the basic configuration involved changes in the alignments and lengths of the breakwater structure, the cross section of the breakwaters used, the size and shape of the turning basin, the location of fill areas, and the location of the launching ramp inside the harbor. A 60-ft-long wave generator and an automated data acquisition and control system (ADACS) were used in model operation
