Installation



River Architect applies on ArcGIS Pro’s arcpy package and needs to be executed with ArcGIS Pro’s conda environment (C:\Program Files\ArcGIS\Pro\bin\Python\scripts\propy.bat). The requirements section provides more details and installation hints for external packages. River Architect is designed as an external application rather than a python package, but its modules can be imported as packages for external use (see the Alternative Run sections in the module Wikis).


Installation with Git Bash/GUI

We recommend downloading and updating River Architect using Git Bash (or Git GUI). Alternatively, River Architect can be downloaded as zip file. However, updates are tricky when River Architect is downloaded as zip file.

Git Bash
GitHub provides detailed descriptions and standard procedures to work with their repositories (read more). The following “recipe” guides through the first time installation (cloning) of River Architect:

  1. Open Git Bash
  2. Type cd "D:/Target/Directory/" to change to the target installation directory (recommended: cd "D:/Python/RiverArchitect/"). If the directory does not exist, it can be created in the system explorer (right-click in empty space > New > > Folder).
  3. Clone the repository: git clone https://github.com/RiverArchitect/program

Done. Close Git Bash and start working with River Architect.

Git GUI
For using Git GUI, open Git GUI and choose Clone Existing Repository. Enter the Source Location: https://github.com/RiverArchitect/program, and the Target Directory: D:/Python/RiverArchitect (or any other directory, but ensure that the directory does not exist). Click Clone. Done.


Update with Git Bash/GUI (re- pull)

Currently, Git Bash (or Git GUI) are the only options to update local copies of River Architect. Before updating River Architect, we recommend to save any files and Conditions produced with River Architect externally (create a save copy).

Git Bash
Open Git Bash and do the following:

  1. Go to the local River Architect installation directory: cd "D:/Python/RiverArchitect/program/" (or wherever River Architect was cloned).
  2. Check the current status: git status
  3. Pull changes: git pull

Please note that merge errors may occur when changes were made in the local copy of River Architect. In this case, Git Bash will guide through the manual merge process. If you modified template workbooks (Fish.xlsx or threshold_values.xlsx): Create a .gitignore file in the /RiverArchitect/ directory. Open the .gitignore file with a text editor and enter the following:


/LifespanDesign/.templates/threshold_values.xlsx
/.site_packages/templates/Fish.xlsx

Save the .gitignore file and close the text editor. Now git pull will no longer overwrite Fish.xlsx and threshold_values.xlsx.

Git GUI
Open Git Bash and open D:/Python/RiverArchitect from the Open Recent Repository list (or wherever River Architect is installed). If not listed, click on Open Existing Repository and select the River Architect installation directory. Then:

  1. Click on Rescan.
  2. Click on the Remote drop-down menu > Fetch from > origin.
  3. Click on the Merge drop-down menu > Local Merge.

Launch River Architect

To start using River Architect:

  1. Right-click on DRIVE:\path\to\...\RiverArchitect\Start_River_Architect.bat and click on Edit.
    • In the Start_River_Architect.batchfile, ensure that the Python path is correctly defined according to the installed version of ArcGIS: call EDIT»"%PROGRAMFILES%\ArcGIS\Pro\bin\Python\Scripts\propy"«"%cd%\master_gui.py". For more information about running standalone Python scripts in ArcGIS Pro’s conda environment, read their descriptions.
    • Save and close Start_River_Architect.bat.
  2. Double-click on DRIVE:\path\to\...\RiverArchitect\Start_River_Architect.bat to start River Architect.
  3. Create a Condition on the Welcome (Get Started) tab.
  4. Analyze and create ecohydraulic paradises for Physical Habitats prefered by target (fish) species with sustainable river design features using lifespan maps.
    Hint: The Quick GUIde sections in the module Wikis provide straight-forward application guidance.

River Architect starts in a GUI that is stored in master_gui.py. Alternatively, the modules can be individually launched by double-clicking on the LAUNCH_Windows_x64.bat in the module folders (not recommended and may be abandoned in future versions).

Program environment setup and batchfile modification


The package is designed for an ArcGIS Pro’s Python3 conda environment. Before launching the River Architect package for the first time, the batchfiles may require adaptions for the system environment. On Windows only (Linux is not yet available because of arcpy issues - we are working on it), set the batch file environment as follows:

  1. Right-click on Start_River_Architect.bat and choose Edit (with Texteditor) or Open with ... and choose a Texteditor software.

  2. Check, and if necessary, replace the path to the good python interpreter:
    Default: "%PROGRAMFILES%\ArcGIS\Pro\bin\Python\Scripts\propy"
    Note: Future versions of River Architect’s will require gdal and rasterio. Therefore, developers recommend to create a new conda environment and to install these packages to that new environment:
    • Open “ArcGIS Pro” and click on the Project pane in the upper left corner
    • Click on the Python tab
    • Click on the Manage Environments button and on Clone default (or manually copy the default environment) to, for example, C:\Python\envs\arcgispro-py3-cust
    • When cloning was successful, restart ArcGIS Pro and go back to the Project > Python tab and click on Add Packages
    • Search for, and install gdal (lib-gdal also works) and rasterio
    • For starting River Architect from an IDE, set the new conda environment as interpreter (e.g., C:\Python\envs\arcgispro-py3-cust\python.exe). The new environment may also be used in the batchfiles.
    • The ArcGIS Pro website provides more information on how to install Python packages.
  3. Save LAUNCH_River_ArchitectWINx64.bat and close Texteditor.

  4. Set default application to open input file type documents (*.inp files):
    Go to folder ...\River Architect\LifespanDesign\.templates\ and right-click on mapping.inp to access the menu Open with .... Choose any text editor, such as Notepad, Texteditor or Notepad++ and click OK.

There is no standard easy way to import ArcGIS’ arcpy package in Python running on UNIX platforms (Apple or Linux). Future versions of River Architect aim at using other packages for geodata processing, which will also run on UNIX platforms (we are currently experimenting with gdal and qgis.core).
After editing the batch files, launch River Architect by double-clicking on Start_River_Architect.bat.

Requirements and dependencies


Python packages

The execution of River Architect requires the following packages, which are part of the standard ArcGIS Pro - Python3 distribution:

  • arcpy
  • argparse
  • glob
  • logging
  • openpyxl
  • os
  • shutil
  • subprocess (not mandatory, also works without this package)
  • tkinter

Additional packages:

River Architect incorporates a modified version of openpyxl, but a more proper way is installing openpyxl with ArcGIS Pro’s package manager. Future versions may additionally require the gdal and rasterio packages (see above instructions).
Furthermore, River Architect requires ArcGIS Pro’s “Spatial Analyst” and “3D” (Volume Assessment only) extensions. Another version of River Architect based on open-source geodata processing packages is planned for the future.

Any folder beginning with a “.” for example .cache or .idea must not be modified or assessed by any other program, in particular during the execution of package methods. Files stored in .templates folders are directly called by the GUIs if user definitions are admitted. At the end of execution, the applied modules have created their output folders, which are indicated in the command prompt.

Other software and dependencies


A workbook editing software such as Excel or LibreOffice is required for modifications of user-defined databases (.xlsx files).

For the visualization of geodata (.shp and .tif files), and mapping with project files (.aprx), an installation of ArcGIS Pro is required. Open-source alternatives are QGIS or SAGA (Please note: There are more GIS alternatives out there.).

Logfiles


Logfiles logfile.log are created in the module directories during every run task. These files contain time-stamped terminal messages of program activities, warnings and error messages. Thus, logfiles enable the user to review process duration and to trace back problems. The handling of potential errors and warning messages are listed in the Troubleshooting Wiki with descriptions of problem sources (cause) and solutions (remedy).
