Description
The Flood Analysis Tool in CFA follows the USGS Bulletin 17B approach (IACWD 1982) for flood flow frequency analysis of unregulated streams. However, CFA is unable to verify whether the stream gauging stations are unregulated or not. For this reason, as with all models, users should have some prior knowledge about the model and its limitations as well as knowledge of the area of interest. The USGS Bulletin 17B method follows the recommendations of Bulleting 15 (WRC-HC 1967) for flood magnitude/frequency study, in which a Log-Pearson Type III distribution is fitted to available flood data. By fitting a distribution to available data, return periods for unobserved and historic floods can be calculated using the parameters of the fitted distribution. This also allows for flood flows of standard return periods, like the 100-year flood, to be interpolated from the fitted distribution.

Notes about Data Sources:

- All Data sources are accessed through the csip-lib-water library

- USGS Data extracted from the National Water Information System (NWIS) by encoded url (i.e. station id, begin/end dates, parameter type): https://help.waterdata.usgs.gov/faq/automated-retrievals

- STORET flood data is not available from the Water Quality Data Portal (by the National Water Quality Monitoring Council) Web Services: https://www.waterqualitydata.us/webservices_documentation/

- CDWR flood data is not available from the Colorado Decision Support System (CDSS) REST Services: http://dnrweb.state.co.us/dwr/dwrapiservice/help#TechInfoHelp&#All&#gettingstarted&#jsonxml
