Greetings to Everybody!

I am looking from some advice regarding a numerical simulation in
FEFLOW, including flow and mass transport in transient state, for an
unsaturated model.

The model was built based on the field data and parameters as taken
from referenced literature. However, for some reason, I have the
feeling that I get too much dispersion through the model domain.

If anyone could give some advice, I can provide more specific
information.

Thank you with anticipation!

Monica
