Hey all,
I'm trying to simulate a lake in a boundary in a 2D model, with Darcy's law. Basically, I set the hydraulic head on the edges of my model to be "H lake" when Y is less than that H, and then Y when Y is greater than H lake. This correctly simulates the changing hydraulic head on the boundary, but it introduces flows from parts of the boundary that are "dry". What I would like to do is keep the head at Y level when the surface of the lake is below that Y coordinate, but restrict that level to only generate outflows (in case I have a recharge on top of my model).
Any way I could restrict my Hydraulic Head Bc to only extract water out of the model when a certain condition is satisfied? Sorry if it's kind of a stupid question, I'm just starting with this software.
Thanks in advance!
