This book was released on 1953 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wave photographs were taken from a ground position about 90 ft above the sea level with an F-56 aerial camaera using an 8 1/4-in. lens pointed essentially parrallel to the wave crests and roughly normal to a pier which extended outward from shore to a distance of about 2200 ft. An electrically driven timer reading directly to 0.1 sec, capable of being estimated to 0.01 sec, was located in the foreground of the field of view of the aerial camera. The exposure interval varied from about 2 sec to about 4 sec with the comera operated altogether manually. The photographs taken with the F-56 aerial camera were arranged in sequence according to time and wave groups. Three different methods for determining wave lengths and wave periods were used. Similar wave photographs were taken a second time. The most difficult of all measurements was identification of the position of wave crests on the photographs. The investigation indicated that waves of a suitable nature (long period, fairly regular waves) give satisfactorily bottom profiles out to depths as much as 30 ft. The reliability increased as the number of waves measured increased.

Available in PDF, EPUB and Kindle. Book excerpt: The report presents a procedure for analyzing aerial photos for depth determination by the wave-velocity method. An attempt is made to determine the accuracy of this method by the statistical approach. This latter analysis, however, is not conclusive in view of the fact that profiles by soundings were not available for the same days on which the aerial photos were obtained. Although the statistical analysis indicates that relatively large errors in depths at individual points are possible, the beach slopes as obtained from the aerial photos and by soundings appear to fall reasonably well within certain general classifications. The procedure for applying the wave-velocity method of depth determination and the statistical analysis for evaluating its accuracy are recommended as a working procedure in any investigation designed to test rigorously the reliability of this method of bottom surveying.
