Hi Chris.
In the RoundLake model, in the end of simulation after (14) days, are calculated:
a) Very low concentrations for the DO (4.58 mg/l)
b) Very high concentrations for the total N (283 mg/l) and
c) Quite high concentrations for the total P (26 mg/l)
For the low concentrations to DO, I reduced the nitrification_coefficient to 0.01 from 0.05 in the file (wq_files>Nitrogen.dat) and the results was normal (DO: 8.13 mg/l), due to the lower consumption O2 during the nitrification process (ΝΗ4==>ΝΟ3). Now, could you suggest me which parameters must be modified to success normal concentrations in Total N and Total P???
