Can EFDC modeling 2D and 3D at the same time?

1,can EFDC modeling 2D and 3D at the same time?
2, How to set in EFDC when modeling 1D, vertical 2D?

Binlichen,

It really depends on how you interpret the results from EFDC model. You can do the 3D run in EFDC with multiple layers. However, if you are only interested in 2D, then you can only look at the depth averaged results and you will be looking at 2D.

Hope it helps.
