Prehistoric painted pottery of southeastern Arizona by Robert A Heckman( Book )

2 editions published in 2000 in English and held by 123 WorldCat member libraries worldwide

"This volume is a guide to the painted ceramics of southeastern Arizona, one of the most interesting, culturally diverse, and relatively unknown regions of the American Southwest--a crossroads and meeting ground for many different prehistoric peoples. The volume was commissioned by the U.S. Army Garrison, Fort Huachuca, for a class on the ceramics and prehistory of southeastern Arizona. Because the class was designed primarily for avocational archaeologists, the guide describes the painted ceramics and prehistory of the region in an informal and easy-to-understand format."

Buhne Point, Humboldt Bay, California, design for the prevention of shoreline erosion : hydraulic and numerical model investigations by Robert R Bottin( Book )

6 editions published between 1984 and 1985 in English and held by 82 WorldCat member libraries worldwide

Two numerical models and two physical models were used to investigate the effects of proposed improvement plans with respect to shoreline erosion at Buhne Point, Humboldt Bay, California. Initially, a numerical tidal circulation model was to determine the tidal current field adjacent to Buhne Point. Maximum flood and ebb tidal currents were identified and used as test conditions for the physical models. A 1:100-scale physical model of central Humboldt Bay included the jettied entrance to the bay, approximately 18,000 lin ft of shoreline inside the bay (including Buhne Point), and underwater contours throughout the central portion of the bay and the area between the jetties. The model was used to determine the wave climate (angle of wave fronts and wave heights along these fronts) in the vicinity of Buhne Point for a series of incident wave conditions and directions (waves propagated through the Humboldt Bay entrance) and for various water levels and tidal flow conditions. A 30-ft-long wave generator, an Automated Data Acquisition and Control System (ADACS), and a model circulation system were utilized in model operation. The output conditions obtained from the 1:100-scale physical model were input into a 1:50 scale physical model of Buhne Point where the effectiveness of various structures proposed for shore protection was evaluated
Breakwater stability study, Mission Bay, California : Hydraulic model investigation by Dennis G Markle( Book )

4 editions published in 1983 in English and held by 75 WorldCat member libraries worldwide

A hydraulic model investigation was conducted using a three-dimensional stability model at an undistorted linear scale of 1:36 (model to prototype). The purpose of the stability tests was to develop a random-placed armor-stone design for a proposed offshore breakwater (to be located seaward of the existing north jetty and middle jetty at Mission Bay, California) that will be stable for nonbreaking wave heights up to and including 16.7 ft at still-water levels of 0.0 and +5.4 ft mllw. Test results indicated that two alternative plans would be adequate for the nonbreaking wave conditions. One plan consisted of two layers of 29,000-lb stone random-placed on 1V-on-2H slopes on the breakwater heads and two layers of 22,700-lb stone random-placed on the 1V-on-2H ocean-side slopes and the 1V-on-1.5H channel-side slopes of the breakwater trunks. The other plan consisted of two layers of 29,000-lb stone random-placed on the 1V-on-2H to 1V-on-1.5H slopes on the breakwater heads, random-placed on the 1V-on-2H to 1V-on-1.5H slopes on the breakwater heads, the 1V-on-1.5H ocean-side slopes, and the 1V-on-1.25H channel-side slopes
Mission Bay Harbor, California, design for wave and surge protection and flood control : hydraulic model investigation by Charles R Curren( Book )

4 editions published in 1983 in English and held by 75 WorldCat member libraries worldwide

A 1:100-scale (undistorted) hydraulic model, reproducing Mission Bay Harbor, approximately 3 miles of shoreline, and sufficient offshore area to permit generation of the required test waves, was used to investigate the arrangement and design of proposed structures for (a) improving hazardous entrance conditions, (b) reducing surge inside the harbor, and (c) eliminating potential flood hazards. The original proposal for harbor improvement consisted of a 2,200-ft-long offshore breakwater. The proposed structures for river flood control consisted of (a) a 1,200-ft-long weir in the middle jetty, (b) various South jetty extensions, and (c) diversion dikes on the middle jetty. Nonstructural flood-control measures consisted of incremental sand plug removal and pilot channels. Two wave generators (70 and 80 ft long), crushed coal tracer material, Styrofoam surface floats, and an Automated Data Acquisition and Control System (ADACS) were used during model operation

Los Angeles and Long Beach Harbors model study : report 6, resonant response of the modified phase 1 plan by Douglas G Outlaw( Book )

4 editions published in 1979 in English and held by 64 WorldCat member libraries worldwide

A study of harbor resonance due to long-period wave excitation was conducted in Los Angeles and Long Beach Harbors hydraulic model for the Modified Phase I improvement plan and compared with resonant response for existing conditions. Proposed improvements for the Modified Phase I plan included dredging of navigation channels and an associated landfill of approximately 200 acres in the Port of Los Angeles, and an Outer Harbor Oil Terminal in the Port of Long Beach. Wave periods ranging from 15.5 to 410 sec with incident direction of approach from the south were included int he study. Previous refraction studies had shown that due to offshore topography, Los Angeles and Long Beach Harbors are well protected from all incident long-period wave directions, except from the south. Results of the study show wave-height amplification, periods of maximum response, and modes of oscillation for various berthing areas. Comparisons of model data for existing conditions and the proposed plan indicated that resonant modes of oscillation in the existing harbor berthing areas were not substantially altered. With the Modified Phase I plan, periods of maximum resonant amplification in existing harbors generally shifted slightly. Resonant peaks in the amplification data generally decreased or increased slightly. For existing conditions, periods of maximum response agreed closely with prototype measurements. In the proposed Outer Harbor Oil Terminal, modes of oscillation either resulted in antinodes in the berthing areas or had relatively low amplification. (Author)
Breakwater rehabilitation study, Crescent City Harbor, California : coastal model investigation by R. Clay Baumgartner( Book )

5 editions published in 1985 in English and held by 61 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
Los Angeles and Long Beach Harbors Model Enhancement Program : measured response of moored ships to long-period waves by David D Mcgehee( Book )

3 editions published in 1991 in English and held by 60 WorldCat member libraries worldwide

The Ports of Los Angeles and Long Beach (LA/LB), California, are conducting planning studies for major expansion. This plan calls for reclamation of nearly 10 sq km of new landfill, construction of 38 new terminals, and the dredging or deepening of over 11 km of deep-draft channels. The development will affect the tidal circulation pattern in the harbor and the harbor resonance characteristics. Adequate circulation is necessary to ensure harbor flushing and acceptable water quality. The objective of the ship motion data collection effort was to obtain calibration and verification data sets for a numerical model of moored ship response to wind and waves. To validate the model, synchronous time series data were needed on the incident wave conditions outside the harbor, the mean water level, the harbor oscillation/response and wind conditions near the moored ship, the complete six degree-of-freedom ship response, and mooring line and dock/fender reactions. In addition, ship characteristics, mooring line geometry characteristics, and loading history were required
King Harbor, Redondo Beach, California, breakwater stability study : hydraulic model investigation by Ernest R Smith( Book )

2 editions published in 1990 in English and held by 60 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)
Los Angeles and Long Beach harbors model enhancement program : prototype wave data summary : final report by James Rosati( Book )

4 editions published in 1998 in English and held by 56 WorldCat member libraries worldwide

This report presents data products from the analysis of seven different wave gauges in Los Angeles and Long Beach Harbors and a directional wave gauge at a nearby offshore site (Platform Edith). These data products were chosen in an effort to summarize all wave data collected during the Harbors Model Enhancements (HME) Program. Data acquisition methods and equipment are documented in this report, along with analysis methods. The emphasis of this report is on summarizing and documenting the available prototype wave data in fulfillment of the wave data collection and analysis tasks of the HME. Between February 1984 and February 1988 wave data were sampled every 2 hr at 1 Hz for 2,048 sec in the harbors. From February 1988 to August 1991, data were collected continuously in the harbors at an average sample rate of 0.25 Hz. Directional wave data were measured offshore at Platform Edith via a PUV gauge between February 1985 and August 1991. Data for this period were collected at 1 Hz for 2,048 sec every hour but reported every 4 hrs. Waves were measured in seven locations in the harbors with highly accurate single-point pressure sensors. Directional wave measurements show that during the winter months most of the waves come from the west, but during the summer, the majority of the waves come from the south (although a significant number still come from the west) and average peak in wind wave energy during the months of September and October. However, low-frequency waves that affect ship motion are present throughout the year
Los Angeles and Long Beach Harbors Model Enhancement Program, effects of wind on circulation in Los Angeles-Long Beach Harbors by William C Seabergh( Book )

3 editions published in 1994 in English and held by 56 WorldCat member libraries worldwide

A previously calibrated numerical three-dimensional hydrodynamic model for Los Angeles-Long Beach Harbors, California, was applied to study the combined effects of tide and wind on circulation. The model was calibrated and verified successfully with field data for a summer wind condition. In this report the calibration is compared to a no-wind condition to understand the effects of typical wind conditions on circulation. Also, wind conditions for approaching (winds from the southeast) and passing (winds from the north) frontal systems, typical of fall-winter weather patterns, were simulated. Results indicated the effects of wind can be significant. Harbors, Long Beach Harbor, Wind-driven circulation. Hydrodynamics, Numerical models, Los Angeles Harbor, Tidal circulation
