对多期水深数据的处理方法进行探讨,提出相应的计算机处理程序。经程序处理后的水深数据,可以找出其冲淤区、绘制冲淤等值线图和冲淤立体图;计算出其冲淤量和冲淤面积。还可以绘制出所测海区任意方向的多期剖面图及水深坡度图,从而揭示出冲淤规律。 The method of processing multi-period water depth data is discussed, and the corresponding computer processing program is put forward. After processing the water depth data, we can find out the scouring and silting area, draw the contour map of scouring and silting and scouring and silting, and calculate the amount of scouring and silting and scouring and silting. It is also possible to draw a multistage cross-sectional view and a deep-water gradient map in any direction of the sea area to be measured, so as to reveal the law of erosion and sedimentation.
