MODFLOW is the USGS's modular hydrologic model. MODFLOW is considered an international standard for simulating and predicting groundwater conditions and groundwater/surface-water interactions.

The Streamer Trace API is a programming interface written in JavaScript designed to add up- and downstream traces to an ESRI ArcGIS API for JavaScript (ESRI JSAPI) web map using the same methods and services created for the Streamer application. 

GWIS (Graphing Water Information System) Javascript library can create time-series plots of information measured at USGS hydrologic data collection sites across the US. Developed by the USGS Texas Water Science Center, the user-friendly interface integrates the open-source dygraphs JavaScript charting library with the hydrologic data provided by USGS water services.

Bandit was the latest in a series of desktop applications aimed at helping bird banders manage and submit their data for banded birds of its time. Bandit was created by the Bird Banding Laboratory (BBL) at the USGS Patuxent Wildlife Research Center, Laurel, MD. Banders can now use the Bander Portal web application to submit their banding and recapture data. 

The Contaminant Exposure and Effects-Terrestrial Vertebrates database (CEE-TV) contains contaminant exposure and effects information for terrestrial vertebrates (birds, mammals, amphibians and reptiles) that reside in estuarine and coastal habitats along the Atlantic, Gulf and Pacific Coasts including Alaska and Hawaii and in the Great Lakes Region.

Frequently Asked Questions for the Contaminant Exposure and Effects-Terrestrial Vertebrates (CEE-TV) Database

iPlover was developed by the U.S. Geological Survey Woods Hole Coastal and Marine Science Center and the USGS Center for Integrated Data Analytics.  It is used by trained and vetted personnel to record information about habitats on coastal beaches and he environment surrounding them.

Wellfootprint computes a raster map of groundwater withdrawals relative to a user-defined "Depth-Rate Index" (DRI), such as a recharge rate. Dividing each well's withdrawal rate by the length per time DRI yields an area for display for each well's 'footprint' as a circle around each well. Symbols for closely spaced wells are merged to visualize the combined withdrawals eq

VS2DI is a graphical software package for simulating fluid flow and solute or energy transport in variably saturated porous media.
