Brian,
Thank you for the prompt reply! I am stuck in the CC model, also it will handle the pH-sensitive nature of boron sorption that Langmuir isn't going to. I very much like the idea of creating my own dummy element, but I am a little stuck on the surface area/porosity issues and how they are handled in GWB. Much of this is not clear to me right now, even spending some time with the manuals and program. I probably need some more clarity using the Qtz setup before I move to the dummy element. I am probably overlooking clear guidance in the documentation, but its so much easier just to ask, sorry.
I have a .gss file with all the aqueous chemistry for waters I want to -flush through the sediments using react
I have a .sdat file for each set of sediments, example 43% porosity
I want to flush until the boron in water value doesn't change, i.e. equilibrium
Where is the best place for me to be specifying my water rock ratio in Flush if I use the qtx+dummy surface model, and the best way to do that?
I see a couple of ways I could set it up, specifying .43 L of solution in GSS, and setting the .57 L of quartz somewhere else, in SpecE8, or in React, or maybe as user variable in GSS that would let me batch this...but then I get lost.
If I know I am doing this water rock ratio right, I can use the CC sediment boron values to test for reasonableness.
Thanks!
Greg
