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...

GW/SW-MST: A Groundwater/Surface-Water Method Selection Tool GW/SW-MST: A Groundwater/Surface-Water Method Selection Tool
The Groundwater/Surface-Water Method Selection Tool (GW/SW-MST) is a spreadsheet-based tool to help practitioners identify methods for use in groundwater/surface-water (GW/SW) exchange and hyporheic studies. GW/SW exchange and hyporheic processes are topics receiving increasing attention from the hydrologic community. Hydraulic, chemical, temperature, geophysical, and remote sensing...
HASP HASP
The Hydrologic Analysis Package (HASP) can retrieve groundwater level and groundwater quality data, aggregate these data, plot them, and generate basic statistics. One of the benefits of HASP is its ability to aggregate two time-series of data into one record and generate statistics and graphics on hat record. By merging two data sets together, users can view and manipulate a much longer...
High-throughput calculations of climatch scores High-throughput calculations of climatch scores
Matching climate envelopes allows people to examine how potential invasive species may match habitats. This repository contains code for using the climatchR package for high-throughput calculations of climatch scores for species using GBIF data. Climatch is based upon the climatch algorithm as implemented through the climatchR package.
Hydrologic Model Evaluation and Time-Series Tools (HyMETT) R-package 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.
inlpubs---Bibliographic information for the U.S. Geological Survey Idaho National Laboratory Project Office 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...
Integrated population model for red knot in Delaware Bay Integrated population model for red knot in Delaware Bay
This is code for an integrated population model developed to understand the effect of horseshoe crab abundance on population demographics of red knot, an Arctic-breeding shorebird. This model was developed as part of the revision to the Atlantic States Marine Fisheries Commission Adaptive Resource Management Plan for horseshoe crabs.
Interactive PHREEQ-N-AMDTreat+REYs water-quality modeling tools to evaluate potential attenuation of rare-earth elements and associated dissolved constituents by aqueous-solid equilibrium processes (software download) Interactive PHREEQ-N-AMDTreat+REYs water-quality modeling tools to evaluate potential attenuation of rare-earth elements and associated dissolved constituents by aqueous-solid equilibrium processes (software download)
Software utilizing PHREEQC with user interface. The PHREEQ-N-AMDTreat+REYs geochemical modeling tools have the fundamental capability to simulate and predict key reactions related to the treatment of acid mine drainage and the formation of treatment solids, including the adsorption of rare-earth elements plus yttrium (REYs) onto hydrous iron, aluminum, and manganese oxides. These new...
Keys Carbonate Budget Calculations and Analysis Keys Carbonate Budget Calculations and Analysis
The code 'Keys Carbonate Budget Calculations', written in R (v.4.0.4; https://www.R-project.org/), uses benthic coral-reef survey data and fish survey data to calculate coral-reef carbonate budgets following the ReefBudget v2 methodology (http://geography.exeter.ac.uk/reefbudget/; Perry and Lange, 2019). The carbonate budgets include estimates (means +/- standard errors) of gross...
