All these functions are here to facilitate the use of repetitive task used in the package.

TNETutils functions

  • TNETutils_findUpstreamSegment() will get the IDs of all segments upstream of a given ID.

  • TNETutils_getDatInfoJ2K() will read the first line of the “HRULoop.dat” or “Reachloop.dat” file and extract the following informations:

    • The line where the data begin in the file.

    • The first and last day of the simulation (and the number of them).

    • All column names in the file and the number of them.

  • TNETutils_getSAFRAN_fromShape() will read all SAFRAN related columns in the shapefile and put them in a data.frame with 3 columns: gid_new, SAFRAN and Rapport.

  • TNETutils_getShape_fromNETCDF() will read the attribute relative to the shapefile in the NetCDF and open it.

TNETdiagnostic functions

This set of function will verify if there is any problems with computation made by other functions.

  • TNETdiagnostic_pbDrainArea() will catch any problems with drain area computations, and display a warning message to the user.

    • If some segments have very little drain area compared to the downstream segment drain area (with a threshold limit by default set to 40%).

    • If some segments have downstream drain area smaller than upstreams ones.

    • If some segments have drain area not calculated (NULL or NaN).
