Enrico,

Since I'm not at all familiar with the area in which you're working I have
no specific suggestions. I did find a web site that summarizes several
models:
<https://stormwater.pca.state.mn.us/index.php/Available_stormwater_models_and_selecting_a_model>.

I've used TR-20 in the past, but every one of my projects has been different
in terms of location, water quality issue, and regulatory requirements.

Not sure I understand your need. I've often worked with hard rock quarry
operators to model topographic changes and storm water flows. The base data
is the smallest scale DEM available for that location which is then modified
as needed. I'm an applied ecologist, an environmental scientist, and neither
an engineer nor a geologist.

You may have to invent your own approach and document what you've done to
demonstrate to non-technical decision-makers why it's both technically sound
and legally defensible. Effectively communicating complex environmental
issues to decision-makers can be the most important and difficult of our
job.

Best of luck,

Rich
