Wave-Velocity Method of Depth Determination by Aerial Photographs.
Abstract
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.
