In SOBEK 3.4 and previous versions, morphological results are written to the following file: *.dsproj_data/<flowmodel name>_output/work/morph-gr.his.

...

1. Start DeltaShell and open your Flow model
2. In the toolbox, open a new script

3. Start your script by importing the necessary modules

   Code Block
   language py linenumbers true
   import os from ModellerFunctions import dsget

4. Next, use dsget to retrieve your Flow model location of the hisfile:

   Code Block
   language py linenumbers true
   flow = dsget.GetFlow1DModel() print(dsget.GetMorHisFilePath(flow))

5. dsget has some functions to inspect this his file. 

   Code Block
   language py linenumbers true
   # To see which output is available in the his file components = dsget.GetMorphologyComponents(flow) # To see the available times timesteps = dsget.GetMorphologyTimeSteps(flow) # The number of timesteps: print('There are %i timesteps of morphological results'%len(timesteps))

6. We might need to plot the difference in initial (timestep 0) bed level, and the bed level after the morphological simulation. You can retrieve the data for this plot in the following way. Note: instead of the timestep keyword, you can use the location keyword to extract a timeseries for one location

   Code Block
   language py linenumbers true
   data_initial = dsget.GetMorphologyResults(flow, component=0, timestep=0) data_last = dsget.GetMorphologyResults(flow, component=0, timestep=len(timesteps)-1)

7. To export this data to csv file, we use standard Python methods

   Code Block
   language py linenumbers true
   # Print in the same location as the *.dsproj file outputpath = os.path.join(dsget.GetProjectPath(), 'morph-gr.csv') with open(outputpath, 'w') as f: for i, forget in enumerate(data_initial)

...

1. : f.write('"%s", %s, %s\n'%(data_initial[i][0], data_initial[i][1], data_last[i][1]))

2. Finally, click 'Run script' or select all and hit Ctrl+Enter. The csv file should be next to your *.dsproj file.

print('There are %i timesteps of morphological results'%len(timesteps))

# Results for bed level (component 0) 
data_initial = dsget.GetMorphologyResults(flow, component=0, timestep=0)
data_last = dsget.GetMorphologyResults(flow, component=0, timestep=len(timesteps)-1)

outputpath = os.path.join(dsget.GetProjectPath(), 'morph-gr.csv')

with open(outputpath, 'w') as f:
    for i, forget in enumerate(data_initial):
        f.write('"%s", %s, %s\n'%(data_initial[i][0], data_initial[i][1], data_last[i][1]))
#endregion
