Erosion by Water The rate and magnitude of soil erosion by water is controlled by the following factors: Rainfall Intensity and Runoff Both rainfall and runoff factors must be considered in assessing a water erosion problem. The impact of raindrops on the soil surface can break down soil aggregates and disperse the aggregate material. Lighter aggregate materials such as very
