Streamflow analysis regions for Alaska and conterminous basins in Canada
This coverage shows the seven streamflow analysis regions (areas having similar hydrologic characteristics) developed for Alaska and conterminous basins in Canada to help formulate regional equations for estimating selected streamflow statistics, including high-duration flow, low-duration flow, low-flow frequency, and peak-flow frequency. Streamflow analysis region boundaries may be used to determine the region or regions containing a gaged or ungaged site's drainage area in order to select the appropriate regional equations from Wiley and Curran (2003) and Curran and others (2003).
