VAW Glaciology Field Course: Glacier Hydrology

• the field instructions are in instructions/.
• the Jupyter-notebooks in the notebooks/ folders which can be used to evaluate salt-dilution gauging data.
• if you prefere, you can do the same with the scripts in scripts/.
• documentation (essentially the notebooks evaluated) is found in docs/, start with 1_intro.md.

Installation

Linux

• install with your Linux-distribution package manager: git, matplotlib, jupyter
• install Julia:
  • download the binaries from https://julialang.org/downloads/
  • unpack it with tar xvvzf name-of-download.tar.gz in a suitable location
  • make sure the julia executable is on your path, e.g. by setting a sym-link to ~/.local/bin
• clone this repo: git clone [email protected]:eth-vaw-glaciology/GlacierHydroFieldcourse.jl.git
• change dir cd GlacierHydroFieldcourse.jl
• start Julia with current folder as project julia --project
• at the Julia repl (terminal) execute: using Pkg; Pkg.update() This will install all needed Julia packages. It will take a while.

Windows

• install the Julia binaries from https://julialang.org/downloads/ (presumably the "64-bit (installer)")

• install PowerShell via the Windows App-Store https://apps.microsoft.com/store/detail/windows-terminal/9N0DX20HK701?hl=fr-ch&gl=CH (I think this is

• install the git binaries from https://git-scm.com/download/win (presumably the 64-bit version)

  • the installer will ask you many questions. Click "next" except when it asks for your Editor: probably use something other than VIM, say Notepad.

• open PowerShell by typing Terminal in the Windows-search

• change directory (folder) to somewhere good (use cd)

• clone this repo: git clone https://github.com/eth-vaw-glaciology/GlacierHydroFieldcourse.jl.git

• change dir cd GlacierHydroFieldcourse.jl

• start Julia with current folder as project julia --project

• at the Julia repl (terminal) execute: using Pkg; Pkg.update() This will install all needed Julia packages. It will take a while.

• at the Julia prompt do using IJulia and using PyPlot. This will most likely ask you to install Jupyter and Matplotlib via Conda. Say "yes"

Running the code

Once install is completed, close Julia. Now

• if you want to work with notebooks: cd notebooks and
  • in Linux run ./start_notebook
  • in Windows open Julia in the PowerShell with julia --project and then execute using IJulia; notebook(dir=".")
• if you want to work with text-files: cd scripts and run julia --project (edit the files in scripts/ in your favourite text editor)

Documentation

Documentation is found in docs/, start with 1_intro.md.
