|Instance of||natural phenomenon|
Headward erosion is the lengthening and cutting upstream of a valley or a gully at its head. The stream erodes away the rock and soil at its headwaters in the opposite direction that it flows. It is accomplished by rainwash, gullying, spring sapping, and the slumping of material into the head of the growing valley. Once a spring sapping has begun to cut back, the erosion is speed up by the steep gradient the water is flowing down. (also retrogressive erosion, headwater erosion, head erosion, upward erosion)
