TnetRUI is a R package to prepare all needed data in order to run T-NET.

Installation

The package can be installed using the following way:

remotes::install_gitlab(repo = 'guillaume.hevin/tnet_rui', host = 'forgemia.inra.fr')

It can be loaded using library(TnetRUI) as any other package.

Dependances

TnetRUI will use the following packages:

  • data.table for data.frame computation

  • qs and ncdf4 for file export and import

  • lubridate for all date manipulation

  • stringr for string manipulations

  • rlist for list manipulation

  • sf for shapefile manipulation

  • raster for raster manipulation

  • whitebox for drain area computation

Whitebox specification

whitebox is used in the function TNETshape_computeAreaDrain() and need some external installation to work.

  1. Download the whitebox binary

  2. Link the binary to the whitebox package

    • The binary needs to be linked to the package using the following sentence
wbt_init(exe_path='/home/user/path/to/whitebox_tools')

Package specification

TnetRUI is divided in 2 differents set of functions: TNET and TNETshape. Each function in the package will start by one of these to sentences.

TNETshape

All Tnetshape function can be use to prepare the river network used for TNET computation.

  • Clean the TOPAGE river network to be usable by TNET (NOT IMPLEMENTED YET)

  • Cut or merge river segments depending on what’s needed

  • Compute drain area of each segments

  • Compute coeficients to dispacth discharge data on the Topage river network

  • Get SAFRAN ID to be use on each segments.

  • Compute segment position for shadow factor computation.

All function can be run using TNETshape_prepare() function.

More info on TNETshape functions can be found here

TNET

All TNET function will be used to create all inputs data needed for TNET:

  • Compute discharge data using J2000 or EROS modelisation.

  • Compute hydraulic data using EstimKart formulas.

  • Compute meteological data using SAFRAN modelisation

  • Put every files in NetCDF format readable by TNET.
