Excerpt from The Bulletin of the Beach Erosion Board Office, Chief of Engineers, Washington, D. C, Vol. 4: July 1, 1950 The boundary around San Pedro Bay in Figure 2 denotes the area covered by the detailed refraction diagrams presented in Figures 3 - 5° These large scale diagrams were constructed using a crest interval of one wave period, Thewave crests have been completed only up to the outer breakwater° In order to show quantitatively the intensity of wave energy for the wave crests at the breakwater and adjacent beaches bar graphs have been drawn° The lengths of the bars are proportional to the refraction factors accord ing to the scale in the legendo The refraction factors have been computed assuming breaking waves only where the bars are located on the beaches west and east of the breakwater.

C, Vol. 7: April 1, 1953 They also found that the proposed project for White Sand Beach is justified by evaluated benefits, but that the limited public interest other than recreational involved in the improvement, and the minor Federal aid for which the project would be qualified did not warrant adoption of a Federal project for protection of this area. They recommended that local interests consider adoption of a project for the protection and improvement of this beach, in accordance with the plan outlined in the preceding para graph. The shore at Giants Neck is privately owned and thus not eligible for Federal assistance in the cost of protective measures.

Excerpt from The Bulletin of the Beach Erosion Board Office, Chief of Engineers, Washington, D. C, Vol. 9: January 1, 1955 Foundation, 1952.meteorological conditions considered result in a point lying below the appropriate curve, then the wave height will not be expected to reach the limiting value (or height of interest); similarly if the weather conditions result in a point on or above the appropriate curve, waves greater than the specified values may be expected to occur (and the unanswered question, as to whether the waves exceed the limiting value by'l foot or by 50, is not important to the determination). A set of curves showing limiting values for generation of 3-foot waves is shown in Figure l, The curves show values of wind velocity and duration, and fetch and decay lengths necessary to produce the limiting waves of 3 feet. They are used in exactly the same manner as the usual generation curves used in wave forecasting, only instead of reading off the height of the generated waves, the decay distance resulting in the specified limiting wave height (3 feet) is obtained. If the actual decay is less than this value, then the waves will be greater than the (3-foot) limiting value; and if it is more, then the wave height will be less than the (b-foot) limiting value. For example, from Figure l, with a wind speed of 20 knots, a duration of 12 hours. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from The Annual Bulletin of the Beach Erosion Board Office, Chief of Engineers, Washington, D. C, Vol. 14: July, 1960 The techniques by which activated material could be monitored in the laboratory are basically twofold: in situ measurements and laboratory measure ments of samples taken from the test area. A sampling program is feasible for laboratory studies but such a program becomes enormously expensive if pursued during a field test. Consequently, it is desirable to design laboratory studies which utilize in-place measurements extensively and to supplement these measure ments with a sampling program. The design of field applications would of course minimize the use of sampling. In this fashion it will be possible to gain valu able experience from laboratory studies which may be applied to field techniques when working in a littoral environment.
