Erosivity r factor
WebR – Rainfall erosivity factor. The rainfall erosivity factor represents the erosive powers of rainfall energy and runoff by measuring the intensity, quantity, and duration of rainfall. The greater the intensity and duration of the rain storm, the higher the erosion potential. This relates to a few different types of erosion, such as splash ... WebPublished R values represent erosivity during an average year. Rainfall is highly variable from year to year and month to month in a year as some month in a year wettest and some are dry. For ...
