Hello! I am trying to calibrate my model with one set of well observations and every time I try to run PEST, it says that the .hob file could not be opened....
Hi: it sounds as if your MODFLOW model is not executing correctly. Check the folder that you are running the model in for the presence of the .GLO and .LST...

Hello, I have built a 3-layered model: quaternary sands on top of siltstone on top of sandstone. Now there are areas where layer1 (sand) does not exist. I do...

This can be done by assigning properties to the particular cell (or number of cells) in first layer (sands) as that of second layer (siltstone). ...

I can think in two options, but you must check the impacts of each one in the results of your model: 1) Import the terrain topography (1st layer top) and 1st...
Thanks for your feedback. I have looked into the manual again and it seems I have to apply a minimum thickness as it says that in Modflow layers must be...

Hi, You cannot remove some cells in MODFLOW. Layers will cover the whole model area. What you can do is; assign the properties of layer above or layer below to...

Hello Albino, I think it's a typical Modflow problem (FD method): a dry cell is going to be dry for the whole simulation. Try to enlarge your cell height and...

I think the difference between one and the other is that a drain takes the water out of the system and there is no interaction with the groundwater, while a...
Cristina, so far I used river, once more people suggested river, and I obtained a good calibration. But we are cheking the fields data and the model is not...
