SWToolbox Software Information
USGS and the U.S. Environmental Protection Agency (EPA) have combined their SWSTAT and DFLOW software programs into a new tool for the low-flow anlaysis, the SWToolbox.
National Streamflow Statistics Program (NSS)
The USGS develops regression equations for estimating streamflow statistics for every state, Puerto Rico, and a number of metropolitan areas in the U.S. These equations have been compiled into the National Streamflow Statistics (NSS) Program for design, planning, management, and regulatory purposes. These estimates are often needed at ungaged sites where no observed flow data are available....
The Groundwater Toolbox: A Graphical and Mapping Interface for Analysis of Hydrologic Data
The Groundwater Toolbox is a graphical and mapping interface for analysis of hydrologic data. It provides methods to estimate many of the components of the water budget for a hydrologic basin, including precipitation, streamflow, base flow, runoff, groundwater recharge and evapotranspiration.
MODFLOW-GUI Version 4
MODFLOW-GUI is a preprocessor and postprocessor graphical-user interface for preparing MODFLOW-96, MODFLOW-2000, MODFLOW-2005, MOC3D, MODPATH, and ZONEBDGT input data and viewing model output for use within Argus Open Numerical Environments (Argus ONE).
