Regional Regression Equations Based on Channel-Width Characteristics to Estimate Peak-Flow Frequencies at Ungaged Sites in Montana Using Data through Water Year 2011

The Montana Department of Transportation (MDT) uses peak-flow frequency data (i.e. 100-year flood) to design highway infrastructure, secure floodplain permits, and perform stream restoration activities. The USGS, in cooperation with MDT, proposes to develop regression equations which use channel-width as a predictor to provide peak-flow frequency estimates to MDT.
