Transient head observation plot

My first thought is that you should check under your MODFLOW drop down menu - there is an "Observations" selection. Look there to make sure that *before* you run MODFLOW, the correct observation coverage is selected. Otherwise the results won't link up with your observation points. That's my best guess as to why you are seeing those results for your observation points.

In addition to what Sean suggested, I would check the method that you are using to assign the head observations to the MODFLOW grid cells. This option is set in the coverage set up dialog that comes up when you double click on a coverage in the project explorer. Near the bottom of the dialog there is a drop down selection box titled "3D grid layer option for obs. pts." and the default is "By z location". You may want to change this option to "By layer number" (especially if you have a 1 layer model or you know the layer where you want your wells assigned). If the "By z location" is what you want then you need to make sure that the z coordinates of your points are correct.

Let us know what you find.

Hi,

Thank you Sean and Alan.

The problem was that I selected the observation in MODFLOW after I run the simulation. I run it again and it works fine.
