Summary

Regression equations, which may be used to estimate flood flows at select annual exceedance probabilities, were developed for ungaged streams in Pennsylvania. The equations were developed using annual peak flow data through water year 2015 and basin characteristics for 285 streamflow gaging stations across Pennsylvania and surrounding states. The streamgages included active and discontinued continuous-record stations, as well as crest-stage partial-record stations, and required a minimum of 10 years of annual peak streamflow data for inclusion in the study. Explanatory variables significant at the 95-percent confidence level for one or more regression equations included the following basin characteristics: drainage area, maximum basin [...]

Purpose

Flood frequency analyses based on data collected at U.S. Geological Survey streamgages are undertaken to estimate the frequency at which floods of specified magnitudes are typically exceeded. These estimates are used for activities such as infrastructure design, flood risk assessment and planning, and development of flood insurance rate maps. Input data files are used to compute flood frequency estimates based on methods described in Bulletin 17C (England and others, 2018).
