climb8: An R package for querying and joining climate or meteorological data with USGS hydrologic data climb8: An R package for querying and joining climate or meteorological data with USGS hydrologic data
This R package, climb8, consists of functions that enable the query and joining of National Oceanographic and Atmospheric Administration's (NOAA) monthly climate data and gridMET daily meteorological data to the time and location of U.S. Geological Survey (USGS) water quality and continuous data. Functions in climb8 can import climate and meteorological data across the contiguous United...
Precipitation Runoff Modeling System (PRMS) version 5.2.0 Precipitation Runoff Modeling System (PRMS) version 5.2.0
The need to assess the effects of variability in climate, biota, geology, and human activities on water availability and flow can be assessed with computer models that simulate the hydrologic cycle at a watershed scale. The Precipitation-Runoff Modeling System (PRMS) is a deterministic, distributed-parameter, physical process-based modeling system developed to evaluate the response of...

Density-weighted proportion (dwp) tool suite Density-weighted proportion (dwp) tool suite
Estimating the number of birds or bats killed at a wind power facility involves adjusting observed carcass counts to account for imperfect detection. To account for carcasses that lie outside the searched area, the count is adjusted by dividing by the estimated proportion of carcasses lying within the searched area or the density-weighted proportion (dwp). The dwp package provides tools...

This repository contains R language source code used to read eight tab-delimited text files of state-level instances of the U.S. Army Corps of Engineers National Inventory of Dams (NID). The text file were generated from spreadsheets, which themselves are column-trimmed versions of spreadsheets that were downloaded from the public interface to the NID. The focus of the repository is on...
GSFLOW: Coupled Groundwater and Surface-Water Flow Model, version 2.2.0 GSFLOW: Coupled Groundwater and Surface-Water Flow Model, version 2.2.0
GSFLOW is a coupled Groundwater and Surface-Water Flow model based on the integration of the U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS; Markstrom and others, 2015) and the U.S. Geological Survey Modular Groundwater Flow Model (MODFLOW-2005, Harbaugh, 2005; MODFLOW-NWT, Niswonger and others, 2011). In addition to the basic PRMS and MODFLOW simulation methods...
