rill erosion takes place when flowing water curves out numerous closely spaced thin chanels while flowing down steep slopes.when rill erosion becomes wider and deeper it forms a heavy type of erosion called gully erosion.
Rill erosion begins when a small stream forms during heavy rain. Gully erosion , a rill channel becomes broader and deeper. Rill erosion is the removal of soil by concentrated water running through little streamlets, or headcuts.
Gully erosion is a highly visible form of soil erosion
that affects soil productivity.
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.
Sheet erosion is a type of erosion which is caused by wind.It is same as wind erosion whereas gully erosion isa type of erosion which is caused by water .It is same as water erosion.

Gully erosion is usually the result of improper outlet design for local surface and subsurface drainage systems.
Runoff, rill, gully, stream, and river.
The type of water erosion that forms larger channels down a steep slope is called gully erosion. Gully and rill erosion are the dominant types of water erosion in the world.
# Inter-rill erosion : The movement of soil by rain splash and its transport by this surface flow. # Rill erosion by concentrated flow in small rivulets. # Gully erosion by runoff scouring large channels (deeper than 1 foot).
