Precipitation Runoff Modeling System (PRMS) version 5.2.1
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 various comb
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 for estima
scNIDaregis, Geospatial processing of dams in the United States from the National Inventory of Dams with a state-level aggregation scheme, demonstrated for selected dams in eight states in south-central region of the United States, and post-processing fea
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 reservoir s
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, several additio
Hydrologic Model Evaluation and Time-Series Tools (HyMETT) R-package
Hydrologic Model and Evaluation Time-series Tools (HyMETT) software facilitates the analysis and evaluation of hydrologic model output and time-series data with functions focused on comparison of modeled and observed data, period-of-record statistics, and trends.
GIS Clipping and Summarization Toolbox
This tool is being provided free to the public in support of GIS specialists who calculate summary information.
inlpubs---Bibliographic information for the U.S. Geological Survey Idaho National Laboratory Project Office
The R package inlpubs may be used to search and analyze 366 publications that cover the 74-year history of the U.S. Geological Survey (USGS), Idaho Water Science Center, Idaho National Laboratory Project Office (INLPO). The INLPO publications were authored by 253 researchers trying to better understand the effects of waste disposal on water contained in the eastern Snake River Plain aquifer and th
PHREEQC Version 3
PHREEQC Version 3 is a computer program for speciation, batch-reaction, one-dimensional transport, and inverse geochemical calculations.
PHAST - A Computer Program for Simulating Groundwater Flow, Solute Transport, and Multicomponent Geochemical Reactions
PHAST Is a computer program for simulating groundwater flow, solute transport, and multicomponent geochemical reactions.
REGOLITH--A Fortran 95 program for estimating soil mantle thickness in a digital landscape for landslide and debris-flow hazard assessment
The computer program REGOLITH is a Fortran program designed for estimating soil thickness over a digital landscape. The program implements various published empirical and process-based models for soil thickness. This command-line program is used in conjunction with Python scripts to prepare input files and automate certain steps.
Digital Shoreline Analysis System v5.1
The Digital Shoreline Analysis System version 5.1 software is an add-in to Esri ArcGIS Desktop version 10.4–10.7 that enables a user to calculate rate-of-change statistics from a time series of vector shoreline positions.
Seed source, not drought, determines patterns of seed production in Sierra Nevada conifers
This release consists of data collected from 26 plots in two national parks over a 19-year period. The data consists of plot-level seed counts for three genera, number of seed traps, live tree basal area, plot area, and climate metrics from the gridmet gridded data set, the daymet gridded data set, the PRISM gridded data set, and two nearby COOP stations.
