Then a group of mathematical models for submarine topography change are established.
然后建立一组反映海底地形及其变化的数学模型。
But submarine topography changed differently in the different area, especially in the kinds of erosion and siltation.
但海底地形变化在不同的地段是不同的，且冲淤变化差异明显。
Based on this, by the visualizing treatment, manifold visual models of submarine topography and its change have been formed in the area beginning from 1968 to 2000 year.
在此基础上，通过可视化处理，形成该区1968至2000年海底地形及其变化的多种可视模型。
The altimetry free air gravity anomaly can describe structure and basin on continental shelves, and its derived submarine topography contains lots of submarine tectonic information.
测高空间重力异常也可刻画陆架构造及盆地分布，由其推算出的海底地形含有大量的海底构造信息。
