aggrading

Multi-DEM approach, which is based on borehole data, is flexible, speediness and effective for sedimentary formation; but it is not suited for stratigraphic system controlled by fluvial erosion and aggrading action.

基于钻孔数据的多层DEM构模技术是构建沉积环境下三维地层模型的有效方法，但该方法对在河流的侵蚀和淤积交替作用下形成的地层建模效果并不理想。

河流侵淤作用下三维地层模型的构建

Aggrading streams heavily charged with bed load may fill their channels nearly to the top of the banks.

带有大量推移质的堆积河流可以把河槽淤高到几乎与岸顶齐平。
