Nays2D modeling results for three reaches in the Oregon Coast Range 6 years after the addition of large wood.

This data set includes the calibrated predictions of Depth, Elevation, Water Surface Elevation, Shear Stress, Vorticity, and Froude Number for three reaches in the Mill Creek watershed, a tributary of the Siletz River in Oregon. The estimated values are for bankfull flow before and after the addition of large wood using Nays2DH, an unsteady two-dimensional hydraulic model. The study sites are located in low gradient reaches draining 5 to 16 km2 and the model was calibrated based on observations of water surface elevation for several flow levels. See details at:
