Estimated Streamflow Using Satellite Data for Selected Rivers in Alaska
Description
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 child item as a Portable Document Format (PDF).
A shapefile (all_sites.shp) is provided to show coordinate locations of the RSQ gage sites along with a comma separated value (CSV) formatted file (ALL_SITES_RSQ_GAGE_DATA.csv) containing all estimated records for the RSQ gage sites. A web map service of the RSQ gage site locations and attribute table is also available on this page.
