Rainfall erosivity layer for the U.S.

swolnyswolny Member, NatCap Staff
Hey all -

When we moved to the new forums, one thing that got left behind was a raster I made a long while back, digitizing the USDA Isoerodent maps of the United States, which can be used as the 'erosivity' input to RIOS and the SDR model if you don't have anything more specific to your location. Just wanted to let people know that it now has a new home, and can be downloaded here.

    Hi @ruralwater, I'm not able to find that file, but I emailed Stacie to see if she still has it. More soon.

    Hi @ruralwater, here's a working link to the erosivity layer: 

  • I assume the values in the provided raster are in MJ * mm * (ha * h * yr)-1? 
  • swolnyswolny Member, NatCap Staff
    Yes. There should be metadata with the raster explaining where it came from and the process, including conversion to metric.

    I was wondering what the proper citation would be for the erosivity raster here. Thanks so much for creating this.
  • swolnyswolny Member, NatCap Staff
    Hm. How about this for citation:

    USDA Isoerodent maps of the United States, EPA publication Fact Sheet 3.1 (2001), "Storm Water Phase II Final Rule". Digitized by the Natural Capital Project.
