houshang 0 Posted June 30, 2012 Report Share Posted June 30, 2012 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?

kcouch 0 Posted July 5, 2012 Report Share Posted July 5, 2012 I would suggest going through the tutorials on how to use pest with GMS. The tutorials can be found on the aquaveo website on the GMS learning center page. There are several pest/calibration tutorials that should help. Also the XMS wiki has quite a bit of information on how to use pest. The wiki can be found here. Quote Link to post Share on other sites
Alan Lemon 3 Posted July 6, 2012 Report Share Posted July 6, 2012 This tutorial shows how to use pest on a similar problem:http://gmstutorials-8.2.aquaveo.com/MODFLOW-AutomatedParameterEstimation.pdf Quote Link to post Share on other sites
houshang 0 Posted July 7, 2012 Author Report Share Posted July 7, 2012 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.

Alan Lemon 3 Posted July 11, 2012 Report Share Posted July 11, 2012 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. Quote Link to post Share on other sites
