Differences in Water Surface Elevation Between Roughness Scenarios: Landcover+50% - Landcover+25%

<p> Raster maps of differences in water surface elevation (WSE) that are based on output from the HEC-RAS 5.0.7 2D hydrodynamic model (Brunner, 2016). The differences are between common flow stages at different roughness scenarios where patches associated with downed trees are 50% greater than landcover roughness and 25% greater than landcover roughness (LC10-LC5, N=44). The WSEs that form these difference have a depth above 20cm and are hydrologically connected to the main channel. </p> <p> Brunner, G.W. (2016).
