What can you use scripting with IronPython for?

Simple (but important!) repetitive tasks

Create new complex functionalities

How difficult is scripting?

Scripts can also be run from the command line

No GUI commands

in scripts can be run in

command line

• Run SOBEK model

• Import measured data

• Get results

• Plot model results vs data

• Enhance charts

• Use objects to calibrate model

• Calibrate a model

• Plot calibration results

• Choose best fit

• Save results as data (spreadsheets) or graphs (images)

• Create SOBEK model:

• Create a SOBEK 3 flow model

• Import branches

• Import cross sections

• Import bridges

• Import lateral sources

• Import weirs

• Set background map

• Adjust data for B.C. and laterals

• Adjust roughness

• Set initial conditions

• Space and time discretization

• Create a Flexible mesh model

• Create a regular grid

• Add bathymetry data (from server) and crop grid

• Add observation point and boundaries

• Add boundary conditions (from server) to the boundaries

• Set spatially varying initial conditions and model parameters

• Run the model

• Extract and visualize output data
