Regional Regression Equations Based on Channel-Width Characteristics to Estimate Peak-Flow Frequencies at Ungauged 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 United States Geological Survey (USGS), in cooperation with MDT, will develop regression equations which use channel width as a predictor to provide peak-flow frequency estimates to MDT. The research will develop channel width-based regression equations that could increase accuracy and reduce uncertainty when determining flood magnitudes and frequencies. Channel width measurements are commonly obtained through on-site surveys. This project will evaluate the use of aerial photography and other remote measurement methods to quickly estimate channel widths to reduce the need for on-site surveys.
