Other common earthworks are land grading to reconfigure the topography of a site, or to stabilize slopes. Geofoam is a new lightweight earthworks technique used to build a bridge overpass on weak soil near Montreal.
An accurate survey of the earthworks can enable them to be interpreted without the need for excavation.

In river management, the term cut or cutting is also used, which refers to the action of short-cutting a meander, in order to speed a waterway's flow.
