WebA concurrent process called lateral erosion refers to the widening of a stream channel or valley. When a stream is high above its base level, downcutting will take place faster than lateral erosion; but as the level of the stream approaches its base level, the rate of lateral erosion increases.

Webwidening rate X eroding length calculation. Widening rate is the lateral movement in ft/yr of the bank. Rates can be estimated using Table 1. The volume is then multiplied by soil density to determine tons. Streams and gullies are usually not eroding throughout their entire length so eroding length needs to be measured. An average bank height WebIn cases of gully erosion, the volume voided from the gully sides is usually computed separately from the gully head cut. This is because headcutting usually occurs at a faster rate than lateral recession. The two volumes are then added to give a total volume voided.

Downcutting, also called erosional downcutting, downward erosion or vertical erosion is a geological process by hydraulic action that deepens the channel of a stream or valley by removing material from the stream's bed or the valley's floor.
