11 open source projects by USGS-R

This R package is designed to obtain USGS or EPA water quality sample data, streamflow data, and metadata directly from web services. See: http://usgs-r.github.io/dataRetrieval/

A bootstrap method for estimating uncertainty of water quality trends

See official repository at: https://code.usgs.gov/water/nhdplusTools

Calculates Hydrologic Indicator stats and fundamental properties of daily streamflow for a given set of data

R tools for geo-web processing of gridded data via the Geo Data Portal. geoknife slices up gridded data according to overlap with irregular features, such as watersheds, lakes, points, etc.

Compilation of tools to aid in hydrologic and water quality analysis.

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). http://usgs-r.github.io/EGRET/
