I ran Modflow using a 2005 engine over my study area and got my first results. The result at one such location is attached herewith. There is a difference between simulated and observed time series. I am unsure if the simulated heads are showing an increasing trend or if the model is trying to reach the observed head values and perhaps may spin up. However, please note that the initial heads are simulated from the steady-state run. Any suggestions/interpretations for further tweaking are welcome.
