Welcome to StreamStats

Rhode Island

Beta version 4 has arrived!

Beta version 4 is now available for most states on a trial basis, and version 3 remains available. Beta version 4 provides a single user interface (at http://streamstatsags.cr.usgs.gov/streamstats/) for all states that are implemented, rather than separate applications for each state, as in versions 2 and 3, and the user interface is more user friendly than previous versions. Information for user-selected ungaged sites currently cannot be obtained using beta version 4 for the States of Iowa, Indiana, North Carolina, and Oregon because of unique functionality for those states that is not yet implemented. Users are encouraged to provide comments and report bugs by use of the Help button on the interface, which also provides access to limited beta version 4 documentation. See below for additional information about versions both 3 and 4.

Please contact the StreamStats by email at support@streamstats.freshdesk.com if you have any questions.

StreamStats for Rhode Island can be used to estimate the magnitude of floods at the 20-, 10-, 2-, 1-, 0.5- and 0.2-percent annual exceedance probability (also referred to as the 5-, 10-, 50-, 100-, 200- and 500-year recurrence interval floods, respectively), and also to estimate the 99-, 98-, 95-, 90-, 85-, 80-, 75-, 70-, 60-, 50-, 40-, 30-, 25-, 20-, 15-, 10-, 5-, 2-, and 1-percent flow durations and the 7Q2 (7-day, 2-year) and 7Q10 (7-day, 10-year) low-flow-frequency statistics. The reports below presents the equations used to estimate the flow statistics, describe the errors associated with the estimates, and describe the methods used to develop the equations and to measure the basin characteristics used in the equations. Estimates produced by the equations are based on the assumption of natural flow conditions at the user-selected sites. Users should familiarize themselves with the reports before using StreamStats to obtain estimates of streamflow statistics for ungaged sites.

 

Interactive Map

 

General information on the Interactive Map application, as well as specific sources and computation methods for basin characteristics are available here.

StreamStats for Rhode Island was developed in cooperation with the Rhode Island Water Resources Board and the Department of Homeland Security, Federal Emergency Management Agency.
