Cristina, so far I used river, once more people suggested river, and I obtained
a good calibration. But we are cheking the fields data and the model is not
finished yet.

And Giovanni, could you please explain why do you think the drain option is
better? I think the otther people would be glad to know your opinion too.

Thanks
Jeane

I think the difference between one and the other is that a drain takes the water
out of the system and there is no interaction with the groundwater, while a
river has a river bed conductance so water can seep into the GW or viceversa,
depending on the gradient.

I would start modeling the rivers as rivers (or streams) and check if you can
calibrate the model. If that doean't work use the drains...
I am in the same boat here. let me know what worked for you.

Good luck!
Cristina.

springs like drain is better.
