A ridge, a ridge and hollow, or a flat bench built along a ground contour. The surface form of a high sediment deposit having a relatively flat surface and steep slope facing the river. A broad channel, bench, or embankment constructed across the slope to intercept runoff and detain or channel it to protected outlets, thereby reducing erosion from agricultural areas.
