Hi,
I was wondering if anyone already used water retention agents added in the soil, such as acrylamide in any project and how this was documented.
Thanks!

I think this concept was discussed a while back when someone was proposing a hidrogel underlayer. The easiest thing to do, from a documentation standpoint, would be to use the 'low' species factor for the vegetation type(s) on your design case, and assign either the 'average' or 'high' species factor for the same vegetation type(s) on your baseline case. That would enable you to account for the differentiation with the soil additive included.
I'm not suggesting it will be the most accurate tabulation of your water use, but I don't believe there's really any other way to account for it.
