Connecticut Streamflow and Sustainable Water Use Estimator (CTSSWUE Version 1.0) application software

Gregory E Granato
This software release provides the database application that runs the Connecticut Streamflow and Sustainable Water Use Estimator (CT SSWUE) computer program (version 1.0). The CT SSWUE was developed by the U.S. Geological Survey, in cooperation with the Connecticut Department of Energy and Environmental Protection, to provide a planning-level decision-support tool designed to help decision makers estimate daily mean streamflows and selected streamflow statistics that can be used to assess sustainable water use at ungaged sites...

Jeremy Newson & Katrin Jacobsen
The National Streamflow Statistics (NSS) Program is a computer program that provides a simple method for applying regional flood-peak streamflow estimates and low flow frequency/duration streamflow estimates.

Exposure-related effects of Zequanox on juvenile lake sturgeon (Acipenser fulvescens) and lake trout (Salvelinus namaycush): code

James A Luoma, Todd J Severson, Matthew T Barbour & Jeremy K Wise
# Overview Three SAS code files were used to analyze data for this study and they included: 1) code to compare the weight of fish distributed to the tanks, 2) code to compare the survival of fish by treatment groups, and 3) code to analyze the weight and condition of fish at exposure termination.

Full Annual Cycle Bioenergetics model of migration applied to Galapagos tortoises Model

Charles B. Yackulic
This code was created to run a bioenergetics-based model of movement for Galapagos tortoises. It calculates energetic surplus or deficit at a daily time scale based on inputted temperature (6 times a day) and NDVI value (a single value per days), as well as the mass of an individual. It then uses dynamic programming to determine the optimal timing of movement between two foraging habitats, given time-series of NDVI in each habitat, and temperatures in...

InterpretSELDM version 1.0 The Stochastic Empirical Loading and Dilution Model (SELDM) output interpreter

Gregory E Granato
The InterpretSELDM program is a graphical post processor designed to facilitate analysis and presentation of stormwater modeling results from the Stochastic Empirical Loading and Dilution Model (SELDM), which is a stormwater model developed by the U.S. Geological Survey in cooperation with the Federal Highway Administration. SELDM simulates flows, concentrations, and loads in stormflows from upstream basins, the highway, best management practice outfalls, and in the receiving water downstream of a highway. SELDM is designed to...

Creating Custom Bar Codes for Tracking Samples from the Field to the Laboratory

Justin L. Welty
This tool is being provided free to the public in support of field and laboratory specialists who would like to create custom bar codes in order to better maintain their field and laboratory samples.

HTCondor examples

Richard A Erickson
This file contains several examples for using HTCondor to scale scientific processing with cluster computing. These examples assume that one has a functioning HTCondor pool with the appropriate software installed and configured (e.g., Docker for the Docker examples; R or Python for R or Python examples). Installing these programs is beyond the scope of these examples, however, we do include the setups we used to setup a condor pool in the HTCondor_setup_Procedures_for_UMESC file.

Highway-Runoff Database (HRDB) Version 1.1

Gregory E Granato
The Highway-Runoff Database (HRDB) was developed by the U.S. Geological Survey (USGS), in cooperation with the Federal Highway Administration (FHWA) Office of Project Delivery and Environmental Review to provide planning-level information for decision makers, planners, and highway engineers to assess and mitigate possible adverse effects of highway runoff on the Nation's receiving waters (Granato and Cazenas, 2009; Granato, 2013; Granato and others, 2018). The HRDB was assembled by using a Microsoft Access database application to...

TRIGRS version 2.1

Rex L Baum & Massimilliano Alvioli
The Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability Model (TRIGRS) is a Fortran program designed for modeling the timing and distribution of shallow, rainfall-induced landslides. The program computes transient pore-pressure changes, and attendant changes in the factor of safety, due to rainfall infiltration. This release, 2.1.0a, includes bug fixes, new output formats, and various optimizations to improve performance of the TRIGRS serial code. These improvements have also been incorporated into a new parallel implementation of...

Thresh - Software for Tracking Rainfall Thresholds for Landslide and Debris Flow Occurrence, Code Repository

Rex L Baum, Jacob C. Vigil & Sarah J. Fischer
The precipitation tracking program, thresh, is a Fortran program designed for computing various measures of precipitation for comparison against established or trial thresholds for landslide occurrence. The program computes cumulative precipitation and precipitation intensity and duration and compares them to thresholds to identify periods of threshold exceedance for use in landslide early warning. This command-line program is used in conjunction with Python scripts and shell scripts to prepare input files and visualize results.


Laura A De Cicco, Robert M. Hisrch, David Lorenz & David Watkins
The U.S. Geological Survey (USGS) developed an R package called dataRetrieval to help simplify the process of discovering and retrieving water quality sample data, streamflow, groundwater, and other data available from Federal hydrologic web services such as National Water Information Systems (NWIS), the EPA Water Quality Exchange (WQX) System, and the National Hydrologic Dataset via the Hydro-Network-linked Data Index (NLDI)

energySim: an R package Spatial

C.D. Martinez
Petroleum resource assessments provide statistical insight into the scale and spatial occurrence of oil and gas accumulations. Similarly, environmental or ecological assessments provide insight into the extent and patterns of ecological resources associated with ecosystems in a region. energySim is an implementation of an approach to link subsurface petroleum resources with ecological resources found at the land surface. The approach relies on Monte-Carlo simulation to estimate the potential impacts of oil and gas development by...


Neil Terry & Frederick D. Day-Lewis
MoisturEC is an R-based GUI used to combine electrical conductivity (EC) data with point moisture measurements for an updated moisture estimate capitalizing on the accuracy of point moisture measurements and the spatial coverage of EC data.

An Open Source Spreadsheet for Calculation of Equivalent Freshwater Altitude in Brackish Water Mixing Zone of an Aquifer with Documentation on Appropriate Use

Eve L Kuniansky
This software release documents an open source spreadsheet that was developed by the USGS in 2007 and modified herein for general use for calculation of equivalent freshwater altitude at wells where the water quality data indicate the well is tapping brackish areas of an aquifer system. One example of this includes coastal wells in the diffusion/mixing or transition zone of the aquifer near the freshwater/saltwater interface. This correction for salinity allows for the inclusion of...

MT3D-USGS: Groundwater Solute Transport Simulator for MODFLOW

Matthew J. Tonkin, Vivek Bedekar, Eric D. Morway & Christian D. Langevin
MT3D-USGS is a USGS updated release of the groundwater solute transport code MT3DMS. MT3D-USGS includes new transport modeling capabilities to accommodate flow terms calculated by MODFLOW packages that were previously unsupported by MT3DMS and to provide greater flexibility in the simulation of solute transport and reactive solute transport.

Point-Source Load Estimation Tool (PSLoadEsT)

Lillian Gorman Sanisaca, Kenneth D. Skinner & Molly A. Maupin
The Point-Source Load Estimation Tool (PSLoadEsT) provides a user-friendly interface for generating reproducible load calculations for point source dischargers while managing common data challenges including duplicates, incompatible input tables, and incomplete or missing nutrient concentration or effluent flow data. Maintaining a consistent method across an entire study area is important when estimating loads to be used as calibration data for regional water-quality models. PSLoadEsT is written using the open-source programming language R and has an...
