Hi Tri Dat,

Generally, you can of course model pumping tests with the 1p model if you consider the density and porosity as functions of the pressure head. Modeling the simplified equation ("transient darcy equation") you showed is IMO not possible, given that you want to set S0 as fixed parameter and leave the 1p model untouched.

However, it is fairly easy to implement a new model in Dumux discretizing the simplified equation, as it is very similar to
the general 1p equation (it is basically the standard heat equation).

I hope that helped,

Timo

Hi Dumuxers,

I would like to know whether it is possible to model a transient darcy equation (with a specific storativity, i.e. a constant term multiplying the time derivative of the pressure, as in the attached image) with the 1p model ?

If it is the case, is it possible to simulate a pumping test for example?

Thank you very much for your help.

Kind regards,

Tri Dat
