Gully-Ravine Relief

a type of relief characteristic of elevated plains areas of platform regions, which over a long period of development have been subjected to normal erosion and dissected by temporary stream channels (hollows, gulches, and ravines). A subsequent stage in development of this relief may witness intensified erosion in the form of gullies brought on by the felling of forests and the plowing up of land. The wedges between the gullies are difficult to plow, and therefore, as the gullies grow, the fields retreat from the brows of the ravines.
