Question

what are the difference between gully and rill erosion?

Answer 1

Gully erosion creates a deep channels that the surface runoffis further enhanced. The water movement is faster, creating a deeper channels. Due to the slow movementof water in rill erosion, the soil particles are finer than gully erosionlands.

Answer 2

A rill is a much smaller channel. A gully was once a rill that got broader and deeper.

There are another differences too:

1- Ratio of width to depth: In gully that ratio is approximately 1:1 but in rills width is greater than itsdepth.

2- In agricultural activities, rills can be removed but gullies can not.

3- In specific area, number of rills are higher than gullies.

4- sediment production of gullies is much higher than Rills.
