Water Yield - PAWC


I’m preparing the required inputs for running the Water Yield Model. As far as I know, there are no global rasters representing PAWC that I can download so I think that I should calculate it (maybe from “the absolute depth to bed rock”, that I downloaded from soilgrid.org?)

Anyway, does anyone have any advice on how to calculate it?

Thank you!


Hi @marco.guzzetti,

I’ve pinged a couple folks who might be able to weigh in here, but we also noticed this portion of the User’s Guide chapter for Annual Water Yield that might be helpful in the meantime: http://releases.naturalcapitalproject.org/invest-userguide/latest/reservoirhydropowerproduction.html#plant-available-water-content-pawc

Hope this helps!

Thank you @jdouglass! It really helps!
