Introduction

These scripts were created to generate basin delineations and other value-added products from Water Survey of Canada hydrometric stations.

Installation

download the latest build from the /built subdirectory and from your R session type:

devtools::install_local(<path to *.tar.gz>)

Dependencies

Most dependencies will download automatically provided that you install using devtools::install_local from a built *.tar.gz file. Others will need to be downloaded and installed manually such as HYDAT

Code

Components

The R package consists of the following files:

  • DEM_tools.R: creates DEM mosaics from local files or from various online FTP servers (e.g. CDED, NED) after downloading them

  • geonames_db.R: For interacting with canadian geographic names database API

  • HYDROBASINS_Rscript.R: For interacting with HydroBASINS tables

  • misc.R: miscellaneous helper functions

  • SAGA_Tools.R: Wrappers for RSAGA functions, mostly those suited to basin delineation and DEM preprocessing

  • spatial_stations.R: Functions to create R Spatial* objects corresponding to hydrometric stations from ECDE table exports or the HYDAT sqlite database

  • station_names.R: Functions to parse hydrometric station names and

  • basin_creation.R: Relies on above files to create basin delineations from a few input parameters such as station names/numbers and coordinates

  • upstReam.R: Used to construct and query large matrices describing upstream/downstream hydrometric station relationships
