2D vertical slice models - confined vs unconfined

Hi,

Just wondering if there is a way to simulate only saturated flow in a vertical 2D slice model which represents both confined and unconfined conditions?  I need the model to use the appropriate storage coefficient depending on whether conditions are confined or unconfined.  However, it seems that the model has to be made 3D to allow any unconfined conditions.  In this case though, then the settings do not really make sense for a vertical slice problem, as only the whole vertical slice can be changed to phreatic. 

Would it work better to use a variably saturated set-up?

Thanks!

Hallo,

I think it would be more straight forward to set up a 2D vertical variable saturated model. Here you can easily apply a fine vertical mesh. And the model will be much more intuitive.

Remind that you have to be careful about the global and local coordinate system, because you have to define the boundary conditions according to your local system (you will find some discussions about this in the forum).

Thanks Zebra - we're just trying to set up a variably saturated model at the moment to see if it works better.
