When you're trying to calibrate a model, it's often helpful to have a plot of the residuals between the observed heads and the simulated heads.
ModelMuse allows you to do that. To do it select "Data|Data Visualization" or just click the "Data visualization" button.
Go to "Head Observation Results."
One of the outputs from MODFLOW is a .hob_out file which contains a comparison between be observed heads and the simulated heads
So select that.
Click Apply.
And here's a plot of the head observations.
Let's look at that again for a minute.
Negative values are colored red. Positive values are colored blue.
The area of the dot is proportional to the absolute value of the size of the residual.
You can see the residuals here.
You can sort them by clicking on any of these columns.
Here's the largest negative residual.
If I want to see that particular object I would click on that row and click "Highlight selected object."
Here is the object that defines that particular observation.
Now when you are calibrating a model, what you would generally want to see is that the negative than positive residuals are randomly distributed across model area and that we didn't have large residuals concentrated in any one particular place.
Now in this particular model it looks like the negative residuals are concentrated in this area and the very biggest residuals are all along this a trend right here so perhaps this model could use a little bit more work.
The letters "USGS" and the words "Science for a Changing World" appear in green.
