  3. GULLY EROSION: Large, wide channels carved by running water. As a rule of thumb, a gully is large enough that it cannot be smoothed out with conventional tillage equipment.

  4. SPLASH EROSION: Direct movement of soil by splashing. Soil particles can be thrown as far as 3 feet by raindrop splash.
    The impact of a water droplet can dislodge soil particles making them susceptible to erosion. Image by NRCS
