These packages include:
- GLRItcl
- usgs-r.github.com: Splash page for USGS-R organization
- EflowStats: Calculates Hydrologic Indicator stats and fundamental properties of daily streamflow for a given set of data
- EGRET: An R-package for the analysis of long-term changes in water quality and streamflow, including the water-quality method Weighted Regressions on Time, Discharge, and Season (WRTDS)
- EflowStats: Calculates Hydrologic Indicator stats and fundamental properties of daily streamflow for a given set of data. A related poster, presented at AGU Fall meeting 2013, can be found here.
- USGSwsBase: Base USGS water science R functions.
- surragateRegression:
- dataRetrieval: This R package is designed to obtain its water quality sample data, streamflow data, and metadata directly from either the USGS NWIS (National Water Information System), but it allows for user-supplied text files as inputs. The program is designed to ingest the data directly into R and structure them into file structures suited for EGRET analysis.
- USGSwsQW: Water quality USGS water science R functions.
- USGSwsStats:Statistic USGS water science R functions.
- USGSwsData: Data sets as data.frames and as text files for examples in the USGS core pacakges
- USGSwsGraphs: Graphical USGS water science R functions
- restrend
- rloadest
- DVstats
- NWCCompare
- rGDP
- functionCollection
All of them can be retrieved from the USGS-R Github repository. Link to other R packages useful for hydrology can be found at the main R post.
Relatively simple question, but is there an R package to calculate discharge? Have many sample sites with area-velocity measurements and need to calculate discharge from these on an annual basis and would like to make the process more efficient and open.
ReplyDeleteDear Unknown,
Deleteyou have to ask to some USGS guy. However, it depends actually what do you exactly mean. If you are looking for a rainfall-runoff model, you can find some of them here: http://abouthydrology.blogspot.it/2012/08/r-resources-for-hydrologists.html (see, for instance, airGR)
