Thanks Grant, I'll have to come back to this one as there is a bit of gathering to be done! Have a look through our FB photos (www.facebook.com/heenandoherty or /heenandohertypl) or our Picasa gallery at www.picasaweb.google.com/heenandoherty in the meantime. Otherwise this is exactly the kind of question that we developed eHD for...take a project and in an highly interactive and open format, get to the bottom of the it and have people learn at the same time while watching and participating. Thanks again and all the best,
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..
