Re: water table does not replicates the topography... and it should!
I just tryed that and that water table is still flat. When i increase the recharge too much it makes a second water table on the top of the model (flat as well).
Maybe is related to the Van Genuchten parameters? Im using Van Genuchten Modified:
alpha = 0.01,
n = 1.964
m = 0.509
sigma = 3.4
all the K = 1 m/d
all other values are set by default.
or maybe the software is uncapable of representing a water table similar to the topography in a strady state model where the topographic gradients are too high? -
Re: water table does not replicates the topography... and it should!
Hi Bjorn
I don´t want to replicate exactly the topography, I would like the model to come up with a solution that would do an aproximation of the topography.
When I run my steady state models (not forcing them with fixed Dirichlet BCs) the water table is always a flat line. Even though the model starts completely saturated and the recharge is very important, it ends up with a flat line.
Is there a way to have ondulations of the water table without forcing the model with fixed BCs? -

Is Feflow capable of doing a water table that replicates de topography in a medium with large variations of slope (mountains like the Andes or the Alpes, for exemple), and where the aquifer is composed consolidated rocks?
I have try with saturated models (and all of it´s variations), unsaturated models (and all of it´s unsaturated parameters from Van Genuchten), and nothing!
Any ideas ?
