    Overview and Help

    The primary functions of SWToolbox are conduct a n-day frequency analysis (most commonly used for computation of 7Q10) and to computer biologically-based design flows.  Flow duration curves can also be computed. The software is designed to facilitate easy import of USGS NWIS streamflow data as well as user-defined text files.

    SWToolbox is built on the EPA BASINS system. The SW Toolbox Documentation found under the Help menu provides information on the functionality of the software. Most of the information on use of the software is general and applies to all applications built on the BASINS platform.

    Download Software

    The latest software release, USGS SWToolbox 1.0.5, is available for download in the link below. Version 1.0.5 corrects known bugs in the previous version and includes some enhancements:

    • Frequency statistics (e.g., 7Q10) for sites with zero flows are now being computed correctly with the Conditional Probability adjustment (CPA) in all routines (Design flow, DFLOW, n-day Frequency grid and report, interactive, and batch mode).
    • "Custom dates" option is applied correctly in"N-day, trend, and frequency" and "Design Flow" routines.
    • SWToolbox 1.0.5 is now compatible with the latest version of R 3.6. It will still run with older versions of R.
    • Descriptive statistics and variables associated with the n-day frequency analysis (e.g., K-values) have been added to the batch mode output. Previously these values were only available from the exported frequency grid in interactive mode.

    The executable file will install the software on Windows machines. Note that R, both 32- and 64-bit, must be installed on a user's system in order to access some functionality under the "Integrated Design Flow" workflow. 

    Software and Manual Release

    The user manual describes the functionality of the software and walks the user through an example session. It is available for viewing and download through the USGS publications warehouse:

    The installation file below will install the software on Windows machines. Note that R must be installed on a user's system in order to access some functionality under the "Integrated Design Flow" workflow. The integration with R has been seamless on Windows 7 and 8 computers, but we have encountered problems with Windows 10 that we are still trying to resolve.
