Variable General Info
Rainfall runoff erosivity ?Comment: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 Universal Soil Loss Equation to estimate annual rates of erosion. When including erosion prediction in OpenNSPECT analysis, the R-factor can be input as a raster file or a constant value. R-factor raster data for the coterminous United States and six of the main Hawaiian Islands are available from the NOAA Coastal Services Center. For areas not covered by these data, a method to calculate R-factor is described in chapter 2 of the USDA Handbook Number 703 (Wischmeier and Smith, 1978). |
