Flood magnitude and frequency of small streams in Indiana: Preliminary estimating equations

This interim report presents preliminary estimating equations developed for the ongoing study, "Flood Frequency of Small Streams in Indiana." The equations were developed by the multiple-regression technique from data collected at 57 crest-stage-gage and 15 rainfall-runoff sites in the study and from 133 streamflow stations in Indiana and 11 in eastern Illinois. Peak discharge was used as the dependent variable, and basin characteristics were used as the independent variables in the analysis. Drainage area and precipitation were the most significant basin characteristics.
