Detailed explanation-1: -Rill erosion is often called Microchannel irrigation. It is the removal of soil by water running through cutoff and watercourse. Rill erosion takes place when water from rainfall does not soak into the soil and runs all over in the same place.
Detailed explanation-2: -Rather than soil washing away in sheets, rill erosion causes the water to cut through the soil, creating small channels on either side that measure no more than 3/10 of an inch in depth. These shallow flow paths through which rainwater flows are an example of rill erosion.
Detailed explanation-3: -Rill erosion is the process by which numerous small channels–less than three inches in depth–are formed. This type of erosion results from concentration of overland water flow associated with sheet erosion.
