CyAN Field Integrated Exploratory Lakes Database (CyAN FIELD)

The Cyanobacteria Assessment Network (CyAN) is a multi-agency project to develop remote sensing technology using satellite data to provide early warnings for cyanobacteria and algal blooms in U.S. lakes and reservoirs. To support remote sensing efforts by CyAN, validating satellite imagery is critical to developing early warning indicators for cyanobacteria and algae blooms. This open access R-scr

RSPARROW

RSPARROW, now available on the USGS GitLab repository, provides the first open-source version of the USGS SPARROW water-quality model

Prism Engine software source code v2.0.0

A continually increasing number of high-quality digital strong-motion records from stations of the National Strong Motion Project (NSMP) of the U.S. Geological Survey (USGS), as well as data from regional seismic networks within the U.S., called for automated processing of strong-motion records with human review limited to selected significant or flagged records. This PRISM (Processing and Review

popcluster: Developing Hierarchical Population Monitoring Frameworks for mobile species with high site fidelity

The software "popcluster" constructs hierarchically nested groupings of similar habitats associated with field surveys while considering biological structure/connectedness (movements between habitats). This approach can support mobile species with high site fidelity where monitoring during surveys occurs on birthing grounds, breeding grounds, or stopovers/seasonal habitat for migratory species. Ea

USGS automated ground motion processing software

The goal of this project is to update, restructure, and consolidate existing USGS ground-motion processing software to incorporate recent advances from researchers at the USGS, PEER, and others. It will standardize tools for multiple USGS ground-motion products and enable scientists within the USGS and the external community to develop and expand ground-motion datasets used in many different appli

USGS ISO Content Specifications

A repository for USGS ISO metadata content specifications. Content specifications define documentation requirements for various USGS data and software products. These specs are used to guide authors in developing robust standardized metadata using the ISO 19115 suite of metadata standards. The repository is used for development, testing and implementation of content spec modules. It contains guida

nhdplusTools: Tools for Accessing and Working with the NHDPlus

Tools for traversing and working with National Hydrography Dataset Plus (NHDPlus) data. All methods implemented in 'nhdplusTools' are available in the NHDPlus documentation available from the US Environmental Protection Agency https://www.epa.gov/waterdata/basic-information.

GCLAS (Graphical Constituent Loading Analysis System): A tool for computing loads of constituents transported in rivers

GCLAS is a program designed to compute daily and annual loadings of constituents transported in rivers. 

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

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 upstr

Source code in R to quality assure, plot, summarize, interpolate, and extend groundwater-level information, visGWDB---Groundwater-level informatics with demonstration for the Mississippi River Valley alluvial aquifer

This page contains extensive source code in the R language supporting groundwater level informatics, and the entry point is the script visGWDB.R. The approximately 4,000 lines of aggregate code requires also extensive external dependencies. The code provides for near arbitrary-scale information processing of observations or recordings of water levels associated groundwater resources. The processin

Stream Channel and Floodplain Metric Toolbox

The Stream Channel and Floodplain Metric Toolbox was developed to demonstrate the feasibility of mapping fluvial geomorphic features from high-resolution bare-earth elevation data.

MT3D-USGS: Groundwater Solute Transport Simulator for MODFLOW

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.
