在研究水下地形的变迁规律时,通常采用对比的方法来比较不同时间或不同历史时期所测的水下地形图,然后利用多种水下断面图来表达水下地形的冲淤状况。本文则旨在利用所绘制的等冲淤线图较直觉地来表达水下地形的冲淤状况。
When studying the changing law of underwater terrain, the contrast method is often used to compare the underwater topographic maps measured at different times or different historical periods, and then use a variety of underwater cross-sections to express the status of underwater terrain scouring and silting. The purpose of this paper is to express the erosion and sedimentation status of the underwater terrain more intuitionally by using such eclogation maps.
