HRU delin next gen

HRU delin used to work with grass6 only. This version brings compatibility with grass7 (and looses compatibility with grass6).

Differences with HRU delin v5

  • Grass7 compatibility
  • Parallelized process in step2, step3 and step4
  • Launch scripts now accept an optional parameter to specify where to find the config file (with any name)
  • Advanced progression display
  • Automatic grass environment building, no more need to build a "case"
  • Flexibility in config file values path (accepts relative and absolute path)
  • Flexibility in user location when running launch scripts
  • New launch script to run all steps
  • No more system calls (to awk, grep, sed...) -> code is now portable to Windows
  • Use pipes between grass tools to avoid some hard disk access (avoid writing some intermediate files)

Install

Dependencies

You'll need some Python3 modules to be able to run HRU delin.

  • TQDM: display progress
  • Pandas: read/write tabular files and perform some computations
  • dbf: write dbf versions of hru.par and reach.par

On Debian/Ubuntu/Mint/... you can install those with your package manager like that:

sudo apt install python3-pandas python3-dbf python3-tqdm

If you don't have administrator rights but still have pip3 installed:

pip3 install --user pandas dbf tqdm

HRU delin

Get the release archive and extract it somewhere. Then make sure the bin directory is in your PATH environment variable. Here is an example procedure:

# go to your home directory
cd
# extract the archive (adapt the path to the archive)
tar xvf Downloads/hru-delin-v7.tar.bz2
cd hru-delin
# add bin directory to your PATH variable
echo 'export PATH='`pwd`/bin':$PATH' >> ~/.bashrc

That's is, now every new terminal will be able to run HRU delin. To check if everything is fine, open a new terminal and type

which hru-delin_step1.sh

It should display something like /home/myname/hru-delin/bin/hru-delin_step1.sh. If not, there's something wrong.
