Summary

This dataset provides estimated Remote Sensing Streamflow (RSQ) data at selected river reaches in Alaska. Reach-specific relations between satellite-derived water-surface elevation data and dynamic surface water extent data were used with a modified form of the Manning's streamflow equation to estimate streamflows. The streamflow estimates were used to create rating tables that define the relation between discharge and satellite-observed water-surface elevation. The streamflow estimates in the gage_data.csv files are derived from these rating tables, interpolated using a polynomial regression equation. Data are organized in child items named for each river reach. Reach-specific details are provided in a README file contained in each [...]

Purpose

Satellite altimetry water-surface elevation (stage) and estimated streamflow (discharge) were used to derive stage-discharge relations for each river reach to support development of methods to estimate streamflow using remote sensing data. River discharge is estimated from June 1 to September 30.
