Calibration of Model with Pest

Recommended Posts

Dear all,

I am trying to calibrate a steady state Modflow model using Pest in GMS8.0.

I have 3 layers with different hydraulic conductivity and one recharge zone in layer 1.

how can I use the pest for calibration of these parameters?

thank you so much for your help.

I have seen this tutorial but in this tutorial there is one layer. I have 3 layers in my model with different hydraulic conductivity and my questions is that i should consider 1 hydraulic conductivity zones or one for each layer.

It depends on how you think the system works. If the 3 layers are the same aquifer and have the same properties then you can just use the same zones for all of the layers. If the 3 layers do not have the same properties then each layer should have its own parameters. You can also assign pilot points to each of the 3 layers. Make each layer have a different parameter and then link the parameter with pilot points.
