The he documentation of QWAST can be found here. In the following new / extra features are described that are not in the documentation.

Calculating different discharge distributions by the Rhine

QWAST uses a discharge distribution table to distribute the discharge from Lobith to the Waal, Nederrijn and IJssel. Different distributions can be calculated. Each distribution is named after the river bed and year was used to calculate it. A distribution can be activated by using the corresponding batch file: e.g. „QWAST_100perjaar_REF2017_bodem2000.xml”. If a batch file is chosen without „bodem” extension, the default distribution is activated: bodem2018.

Adding different demand for keeping local waterlevels (peilhandhaving)

It is possible to import different water demand for keeping water levels from another scenario:

  1. Copy the new water demand to the import folder „PEIL” (like ZW_LHM_MozartDistrict_S2050VPowd.nc)
  2. Copy the import files of the scenario you want to calculate to the import folder „USEPEIL”
  3. Run ImportPEIL
  4. Run USEPEIL – this can be run from the batch


Post-processing


Post-processing includes Python scripts calculating effect on shipping and agriculture and creating a dashboard from the results.

They require Python, and the following side packages:

  • matplotlib
  • openpyxl
  • scipy


The script calculating effects on agriculture contain Geopandas. The installation of Geopanas is the following (this guide is valid for an older version, the versions can be replaced, e.g. Python39):

Installing geopandas using pip


This is assuming Python is installed in : c:\Python\Python36

################


In this guide we explain the steps to install geopandas. It is very important that these steps are followed in the right order.

Otherwise the installation might become corrupted.

Note that everytime a file needs to be run in command window, this needs to be done as ADMINISTRATOR.


Step 1: Uninstall any dependencies (which might have accidently been installed) by running geopandas-uninstall.bat in cmd as administrator.


Step 2: Install Microsoft Visual Studio Build Tools 2019 by running the file vs_buildtools__2074514829.1566813139.exe

- During installation when it asks which components to install, select C++ build tools

- ensure the latest versions of MSVCv142 - VS 2019 C++ x64/x86 build tools and Windows 10 SDK are checked

- Click on install


Step 3: Modify System Environment Variables

- the system environment variables are found by searching for envi in your Windows Search button

- Add a System Environment Variable with name: INCLUDE pointing at C:\Program Files (x86)\Windows Kits\10\Include\<version>\ucrt


Step 4: Run geopandas-installation1.bat as administrator in CMD.

- This will install GDAL


Step 5:  Modify System Environment Variables

- the system environment variables are found by searching for envi in your Windows Search button

- Edit the System Environment Variable with name: PATH and add an extra line pointing at c:\Python37\Lib\site-packages\osgeo

- Note that you do not delete the other lines at your PATH environment variable, only add a new one.


Step 6: Run geopandas-installation2.bat as administrator in CMD.

- This will install all other dependencies on GDAL


step 7: copy FileGDBAPI.dll to c:\Python\Python36\Lib\site-packages\osgeo\gdalplugins\


Step 8:  Modify System Environment Variables

- Add a System Environment Variable with name: GDAL_DRIVER_PATH pointing at c:\Python\Python36\Lib\site-packages\osgeo\gdalplugins

- Edit the System Environment Variable with name: PATH pointing at c:\Python\Python36\Lib\site-packages\osgeo\gdalplugins


Step 9:

- check if installation was succesful by running gdalinfo
