GIS and Hydraulic Model data in Support of a Geomorphic and Hydraulic Assessment of Glacial Outburst Floods on the Snow River near Seward, Alaska
Provided here are three data packages: (1) geospatial vector data showing mapped main channels and alluvial fan extents in the lower 10 kilometers of the Snow River flood plain near Seward, Alaska as part of an assessment of river channel stability under an outburst flood regime, (2) a height-above-river raster produced from 2008 lidar bare-earth elevations for the lower 10 kilometers of the Snow River flood plain, used as part of a geomorphic assessment to identify areas susceptible to inundation and erosion during outburst floods from Snow Lake, and (3) input (raw survey data, computational mesh, hydrologic boundary conditions) and output data for a 2-dimensional hydraulic and sediment transport model of the lower Snow River flood plain near Seward, Alaska.
