* » Abstract

The rainfall-runoff erosivity factor (R-Factor) quantifies the effects of raindrop impacts and reflects the amount and rate of runoff associated with the rain. The R-factor is one of the parameters used by the Revised Unified Soil Loss Equation (RUSLE) to estimate annual rates of erosion. This product is a raster representation of R-Factor derived from isoerodent maps published in the Agriculture Handbook Number 703 (Renard et al.,1997). Lines connecting points of equal rainfall ersoivity are called isoerodents. The iserodents plotted on a map of the coterminous U.S. were digitized, then values between these lines were obtained by linear interpolation. The final R-Factor data are in raster GeoTiff format at 800 meter resolution in Albers Conic Equal Area, GRS80, NAD83.
* Purpose

These data are represented in raster format for use with the Open source Nonpoint Source Pollution and Erosion Comparison Tool (OpenNSPECT).

Process Steps

Process Step Number 1
» Description

The rainfall-funoff erosivity factor was estimated from the R-Factor maps for the coterminous U.S. given in the Agriculture Handbook number 703. A line shapefile approximation of the printed map was generated via "heads-up" digitizing. The final raster map was produced using the Topo to Raster command in ESRI ArcGIS 10.x.
