Does anyone know where I can find some literature values for the diffusion
coefficient for saline water in an aquifer? I have searched and found very
little, only conflicting information. The tutorial tells you to use 10^-10 m2/d,
but the manual (older version) which discusses Henry's problem says that they
used 1.62925 m2/d. They are obviously many orders of magnitude different, which
is worrying!
Also, is it possible to change the diffusion coefficient once you have set up a
transport variant in SEAWAT? The option is there under the species parameters
when you first apply the values, but if you return later the option is no longer
on the list. Do I have to add a new species from scratch or is there a quick
way?
I have a potential source for the diffusion coefficient, but still wondering
about the SEAWAT problem!
Thanks,
Matt
