We have a hydrodynamic flow model, which has been built with Sobek 2.12, of the fluvial system around Zwolle. The model has been completely set up, except for the Boundary condition at one of the tributaries, at Boxbergen, and the roughness of both main tributaries. We also have a time series of water level measurements at the entrance of the channels which flow across the center of Zwolle. Using this information, build a script to automatically calibrate the model. 
The workflow of this tutorial has been divided into the following steps:
1) Import required libraries.
2) Import current model and measured data.
3) Compare current results with measurements.
4) Take objects that will be used for model calibration.
5) Loop running model for different parameters combinations.
6) Add to the previous plot the results of these runs.
7) Calculate goodness of different cases and select the best fit.
8) Export results.
