As more rain falls, the Headward Erosion Headward erosion takes place close to the source of the river as throughflow and surface runoff. It causes erosion at the valley head (the point the water enters the river channel), and increases the length of the river channel.

This study, therefore, investigates gully heads in the field to (1) evaluate the accuracy and resolution of the DEMs used and (2) examine the temporal variations in gully head morphology and soil erosion rates in response to a range of Headward erosion: | | ||| | Headward erosion is demonstrated in this 1906 pho World Heritage Encyclopedia, the aggregation of the largest online encyclopedias available, and the most definitive collection ever assembled. Headward erosion is erosion at the origin of a stream channel, which causes the origin to move back away from the direction of the stream flow, and so causes the stream channel to lengthen. Headward erosion is a fluvial process of erosion that lengthens a stream, a valley or a gully at its head and also enlarges its drainage basin.
