Field channel-width measurements for selected streamgage sites in Montana

The WY-MT WSC conducted a study to develop regression equations for estimating peak-flow frequencies in Montana, using channel-width characteristics. Channel widths were measured in the field at 69 streamgage sites.

To aid in parameterization of mechanistic, statistical, and machine learning models of hydrologic systems in the Wyoming StreamStat study area, flow-conditioned parameter grids (FCPGs) have been generated describing upstream basin elevation, slope, level III ecoregion codes, land cover classification, waterbodies, first of the month snow water equivalent (Jan-Jun), soil type, average soil permeability, evaptranspiration Spring and Summer, and modeled 30-year normal climatologies of average annual total precipitation, average monthly total precipitation, average annual daily mean temperature, and average monthly daily mean temperature values within the Wyoming StreamStats study area.
