Can occur on nearly level land or on sloping land.

occurs on sloping land

where small channels are formed by running water.

can be masked by normal tillage practices.

occurs when rills continue to wash away and become more severe.

More likely on steeper slopes and cannot be smoothed by normal tillage practices

So large the equipment cannot cross them

Usually begin to form near the bottoms of slopes or on steep slopes
