Gretings!

I am looking for advice regarding the model I have built in FEFLOW-
flow and mass transport in transient state, for an unsaturated
model.

The model is based on conceptual hydrostratigraphy, 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 anybody could give me some advice regarding this issue, I can
provide more detailed information.

Many thanks,

Monica
