Available in PDF, EPUB and Kindle. Book excerpt: During September and October 1986, the US Army Engineer Waterways Experiment Station's Coastal Engineering Research Center (CERC) hosted SUPERDUCK, a nearshore processes experiment, at its Field Research Facility located at Duck, North Carolina. The objectives of SUPERDUCK were to develop an improved understanding of coastal processes (currents, waves, sediment transport, and nearshore geomorphology) under a wide variety of conditions and to collect data essential to the development of improved numerical models of coastal phenomena. SUPERDUCK benefited from the cooperative efforts and resources of engineers and scientists from CERC, 6 other government agencies, 10 universities, 3 foreign countries, and 15 Corps of Engineers district and division offices. This report describes the 30 experiments that comprised SUPERDUCK and summarizes the data sets collected. SUPERDUCK was organized into three phases: a nonstorm wave phase conducted during September, a storm wave phase carried out during October, and an all-weather phase. This is the first in a series of reports which will be published summarizing the data and findings of this unique effort.

Available in PDF, EPUB and Kindle. Book excerpt: During September and October 1986, the US Army Engineer Waterways Experiment Station's Coastal Engineering Research Center (CERC) hosted SUPERDUCK, a nearshore processes experiment, at its Field Research Facility located at Duck, North Carolina. The objectives of SUPERDUCK were to develop an improved understanding of coastal processes (currents, waves, sediment transport, and nearshore geomorphology) under a wide variety of conditions and to collect data essential to the development of improved numerical models of coastal phenomena. Critical to the success of SUPERDUCK was the collection of a basic suite of bathymetric surveys and instrument measurements by CERC's Field Research Facility. The measurements included nearshore current, tide, incident directional wave, and meteorological data. In addition, a series of 14 surveys of the bathymetry in the experiment area was collected.

Book excerpt: This report summarizes the primary data sets collected during the DELILAH nearshore experiment held in October 1990 at the Field Research Facility, Coastal and Hydraulics Laboratory, U.S. Army Engineer Waterways Experiment Station. DELILAH was designed to investigate the physics of the nearshore zone using a large array of stationary and mobile instruments, video cameras, radar systems, and precision surveys. This report was prepared to document and publicize the DELILAH data set. It complements a growing series of technical papers, reports, theses, dissertations, and other results based on DELILAH data. These data are available electronically on-line or via other media such as CD-ROM.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the present state of knowledge on infragravity wave motions (nominally 0.003 to 0.05 Hz). Theoretical and observational studies are presented. Most of the studies discussed herein have been published elsewhere, however a few studies discussed in chapter 4 are presented for the first time in this report Measurements of nearshore waves and currents have shown that a significant amount of the total energy can be contained in the infragravity band, and on highly dissipative beaches the infragravity wave variance often dominates over energy in the incident wave band(0.05 to 0.3 Hz). An 8-month data set of infragravity variance measured at 8-m-depth at the shoreline (runup) was compared with incident wave variance. Analysis of the 8-m-depth data showed that high mode edge waves account for about 50 percent of the total infragravity variance, and as high as 80 percent at times. Significant edge wave heights greater than 20 cm were observed at the 8-m depth. Infragravity wave variance was shown to have a higher correlation with swell variance (C = 0.95) than with sea variance (C = 0.61). This report was motivated, in part, by the need to determine the significance of infragravity waves on coastal erosion and structure damage and by the desire to improve coastal engineering solutions to problems associated with nearshore processes.

Available in PDF, EPUB and Kindle. Book excerpt: Previous investigations of longshore currents have included simplifying assumptions and restriction (such as a planar beach, a steady and depth uniform flow, spatially-variant bed shear stress and turbulent momentum exchange, and the exclusion of surface wind stress. These assumptions are quantitatively investigated by calculating the relative importance of each term in the longshore momentum balance with an emphasis on the relative importance of wind forcing across the barred nearshore. Wind and wave forcing of longshore currents across a barred beach are examined using both a numerical model and field measurements. A local momentum balance was measured at various locations across the surf zone during the SUPERDUCK experiment held at the USACE CERC Field Research Facility, Duck, N.C. in October 1986. A moveable sled was instrumented with pressure, current, and wind sensors to measure the various terms in the longshore momentum equation. Stability-dependent atmospheric drag coefficients for the surf zone are determined from wind stress measurements acquired just beyond the surf zone and wind speed measurements acquired from an anemometer atop the 9 m sled mast. Breaking waves were visually identified and electronically marked on the data tapes. Keywords: Ocean currents; Air water interactions; Nearshore surf zone; Wind stress; Theses. (EDC).
