The U.S. Geological Survey is committed to enhancing and expanding information sharing and sound data management practices. Science teams directly use ScienceBase as an information management and collaboration platform and to release scientific data. ScienceBase is a central location that provides access to aggregated information derived from many data and information domains.

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. The program models rainfall infiltration, resulting from...

SeriesSEE is a spreadsheet add-in for viewing time series and modeling water levels that was developed in Microsoft Excel 2010.

The Soil-Water-Balance (SWB) model has been developed to allow estimates of potential recharge to be made quickly and easily. The code calculates components of the water balance at a daily time-step by means of a modified version of the Thornthwaite-Mather soil-moisture-balance approach.

Estimates the total number of species from species presence-absence data on multiple sample sites or occasions using model M(h) from program CAPTURE.

The Massachusetts Reservoir Simulation Tool is a screening-level model developed to examine the effects of reservoirs on the natural streamflow of streams in Massachusetts. The Massachusetts Reservoir Simulation Tool simulates the daily water balance equation of a water supply reservoir and estimates the magnitude, frequency and duration of spillage below the dam over the period of...

The National Map, a collaborative effort between the USGS and other agencies and partners, includes ortho imagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures, and land cover.

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...

TSPROC (Time Series PROCessor) is a software package designed to assist in the calibration of models by editing and distilling time series datasets into more meaningful observations to be used in the optimization objective function. TSPROC uses a simple scripting language to process and analyze time series.

The computer program UFINCH (Unit Flows in Networks of Channels) can be used to simulate unit (15-minute) flows in a network of streams defined within the medium resolution National Hydrography Dataset Plus with value added attributes (NHDPlus, v. 2).

All Landsat 7 ETM+, Landsat 4/5 TM, Landsat 1-5 MSS, EO-1 ALI, EO-1 Hyperion, MRLC, and Tri-Decadal data sets available; LP DAAC ASTER and selected MODIS data holdings also available. Browse-based for enhanced visualization.

Designed to facilitate the study of seismicity associated with volcanic activity.
