Abstract
The measured values for depths and deposits, as measured with a fan echo sounder, are subject to errors due to the diffraction of sound in water bodies and the movement parameters of the survey vehicle. Said errors must be analysed and eliminated, by extensive measurements of the average speed of sound and of the movement of the vehicle. As a rule a region to be surveyed will be swept in tracks, in such a way that the bands surveyed by the fan echo sounder overlap. The same bed elements in an overlap region are, thus, determined more than once. Consequently, in said overlap region, differences in depth are determined, which, by means of multiple linear regression analysis are minimized, or, better, optimised. In this manner, correction factors for the mean speed of sound and for the displacement parameters pertaining to the survey vehicle are calculated. The surveying of the bed-profile of a stretch of water is improved, by use of the disclosed method and rendered independent of an online evaluation during the survey voyage.
