Interpretive Summary: The runoff curve number method remains a widely-used hydrologic modeling tool, and its use through the Natural Resources Conservation Service computer application WinTR-20 is expected to continue for the foreseeable future. To facilitate timely updates and revisions, as well as online deployment, a web-service version of the computational engine from WinTR-20 was developed and implemented. The web service retains the full computational abilities of the WinTR-20 application, but does not include the graphical user interface and its associated features. By implementing the computational engine as a service, it can be reused and repurposed for other current and future applications. The web service and a web page client that provides access for a simple application of the service are available for public use.

Technical Abstract: Despite its simplicity and limitations, the runoff curve number method remains a widely-used hydrologic modeling tool, and its use through the USDA Natural Resources Conservation Service (NRCS) computer application WinTR-20 is expected to continue for the foreseeable future. To facilitate timely updates and revisions, as well as online deployment, a web-service version of the computational engine from WinTR-20 was developed and implemented through a partnership of the NRCS, the USDA Agricultural Research Service and Colorado State University. The web service retains the full computational abilities of the WinTR-20 application, but does not include the graphical user interface and its associated features. By implementing the computational engine as a service, it can be reused and repurposed for other current and future applications. The web service and a web page client that provides access for a simple application of the service are available for public use.
