  Hands-on exercise

  For the hands-on exercise, we will provide you with a new exercise script. In the beginning of the hands-on session, we will fetch the exercise script together. However, you can pull the script (exercise4_wateruse.Rmd) already before the session and browse it through if you like (this is voluntary). If you'd like to watch a recap on how a git pull is performed, see the hands-on training recordings on Teams.

  We will go through the exercise script step by step during the hands-on sessions. Again, the script contains few tasks marked with # TODO, which you can try filling in. We will provide model answers to all tasks after the session in another script.

  For potential use in your home assignments, we also provide a raster layer depicting environmental flow requirements (EFR) in Data/wateruse/EFR_fraction_annual_1971_2010.tif. This describes the fraction of discharge/runoff used by the natural environment. See details in the tab Supporting materials (R and Data) and in the metadata text files in the course repository.

  Written instructions on how to update course material are given below.

  1. Open your project from the wp-course-fall22.Rproj file
  2. In RStudio, select Tools -> Shell
     
     
     
  3. Verify that the shell is in the wp-course-fall22 folder. In Aalto VDI, the current directory of the shell is highlighted in yellow. If there's a cyan (master/main) tag after the path, the shell is in the correct directory. Changing directories can be done with the command cd path/to/directory.
     
     
     
  4. Commit any previous work according to the instructions in this video (note that the video is from 2021). The working tree should be clean as shown below. The output before the working tree can be "Your branch is XXX commits ahead of 'origin/master'" but that is expected and nothing special needs to be done for it.
     
     
     
  5. Type git pull into the shell and press enter.
  6. The shell pulls the changes from the version control system to your folder wp-course-fall22.
  7. If you pull again, you should get "Already up to date." which means that you're good to go.

  
  

  Home assignment

  1. Discover water use patterns and trends in your study area 

  Instructions:

  1. please develop your own research question
  2. produce one page pdf (A4/A3) with following structure: a) title; b) research question and short introduction; c) maps, graphs, etc of the results with captions d) interpretation of the results

  4. once you are happy with the end result, please submit the work (see below Submission)

  
  Ideas for research questions - please note that from now on, innovative research questions and set up will result higher points: 

  • Irrigation water consumption trends vs cropland expansion
  • environmental flows compared to human induced water uses
  • trends in water use within different parts of a basin / trends in share of different water use sectors over time

  
  This weeks illustration type: vector graphic map and '100% stacked bar graph'; include either one to the home assignment! See example charts under 'Visualisation guides and examples' -tab 
  

  Submission: please submit the assignment by using the submission icon below. 

  
  2. Final presentation

  I have now opened the tab for the final presentation - please take a look. It would be good to start slowly thinking about the presentation and what you would like to present in it.
