StreamStats is a Web application that incorporates a Geographic Information System (GIS) to provide users with access to an assortment of analytical tools that are useful for a variety of water-resources planning and management purposes, and for engineering and design purposes.

Automatically determines the earthquake type (subduction zone interface, active crustal shallow, stable continental region, etc.) and the earthquake focal mechanism.

ArcGIS ArcMap add-in, when using this tool, a user can: 1) create a date prioritized composite raster from a collection of raster layers 2) create a lookup raster for the composite raster that identifies which input layers were used to create the composite raster 3) create a divergence raster where pixel values represent the divergence from a user specified value

The Composite Raster and Divergence Tool is an ArcGIS ArcMap add-in

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.

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 is a particle-tracking post-processing model that computes flow paths using output from MODFLOW.

The MetadataWizard is a useful tool designed to facilitate FGDC metadata creation for spatial and non-spatial data sets.

Capture-recapture software to correct raw counts of wildlife fatalities using trial experiments for carcass detecition probability and persistence time.

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 is an unstructured grid version of MODFLOW for simulating groundwater flow and tightly-coupled processes using a control volume finite-difference formulation.
