Software
An official USGS software project is code reviewed and approved at the bureau-level for distribution.
SeismoTectonic Regime Earthquake Calculator (STREC)
Automatically determines the earthquake type (subduction zone interface, active crustal shallow, stable continental region, etc.) and the earthquake focal mechanism.
Composite Raster and Divergence Tool
Composite Raster and Divergence Tool
The Composite Raster and Divergence Tool is an ArcGIS ArcMap add-in
SPARROW modeling: Estimating contaminant transport
SPARROW (SPAtially Referenced Regression On Watershed attributes) models estimate the amount of a contaminant transported from inland watersheds to larger water bodies by linking monitoring data with information on watershed characteristics and contaminant sources.
Chemical Mixtures Software
The chemical mixtures software is a collection of computer programs for investigating the composition, occurrence, distribution, and potential toxicity of chemical mixtures. The software is designed to assist with selecting specific mixtures for future research, identifying the causes for the occurrence of specific mixtures, and discovering the effects of mixtures.
MODPATH: A Particle-Tracking Model for MODFLOW
MODPATH is a particle-tracking post-processing model that computes flow paths using output from MODFLOW.
Metadata Wizard
The MetadataWizard is a useful tool designed to facilitate FGDC metadata creation for spatial and non-spatial data sets.
fatalityCMR
Capture-recapture software to correct raw counts of wildlife fatalities using trial experiments for carcass detecition probability and persistence time.
CE-QUAL-W2 - Hydrodynamic and Water Quality Model
CE-QUAL-W2 is a water quality and hydrodynamic model in 2D (longitudinal-vertical) for rivers, estuaries, lakes, reservoirs and river basin systems. W2 models basic eutrophication processes such as temperature-nutrient-algae-dissolved oxygen-organic matter and sediment relationships.
MODFLOW-USG: An Unstructured Grid Version of MODFLOW for Simulating Groundwater Flow and Tightly Coupled Processes Using a Control Volume Finite-Difference Formulation
MODFLOW-USG is an unstructured grid version of MODFLOW for simulating groundwater flow and tightly-coupled processes using a control volume finite-difference formulation.
