Parametrization of pounds and swales in QSWAT+

[Judith Eeckman]

Dear all,

I am tring to add pounds and swales in QSWAT+.
I added the pounds as reservoir, with the pounds that are connected to river network with code 2 ('Pounds') and those that are not connected with code 4 ('Playa').
For the swales, I modified my land use map where the swales are, and I created a new LandUse Management in SWAT+Editor, with the characteristic of the swales (CN, Manning, Grasswtaerway,..). And the I assigned this LU to the HRUs of the swale.

But finally, I get that the HRUs of the disconnected pounds and the HRUs of the swale produce a lot of runoff (surq_gen), with a high wateryield of those HRUs and very small percolation. But it should be the opposite: pounds and swales are suppose to infiltrate water.

How to parametrize pounds and swales to represente infiltration?

Additional questino:

Is the 'Return Flow' amount included in the 'Perc' variable?

Many thanks,
