I would love to participate in this. I've done minimal earth works (transfer swales, pond-making,
hugelkultur swales) but I would like to expand my understanding of
water management. Perhaps, for the sake of keeping it accessible to novices like myself, could you please give us a rundown of what we're looking at. What do RV1, TC16, D3 stand for? Are the arrows showing the movement of water and the straight lines the
berms? How does one establish the topography of a property? I use Sketchup but I'm not sure it's accurate or even the correct way to do it.
I'm a good interweb scrounger and I'd like to help how I can..
