An Archive for High-Resolution Hydrodynamic-Sediment Transport Model Output: An Example for Use in PyMT Geomorphic Models

This dataset includes the Regional Ocean Modeling System (ROMS) output used in the Undzis and Moriarty (2025) demonstration project. For this project, ROMS was implemented for July 1 – August 5, 2019, for the Alaskan Beaufort Sea shelf.

Files in this archive include: 

Output from ROMS: ocean_his_beaufort_rivers_13rivs_nosections_chaflaradnudclm_7932171_subset_bed_his1thru5.nc

Model Grid Used as Input for ROMS: KakAKgrd_shelf_big010_smooth006.nc

Key variables in each of the files include:  

Variables for ocean_his_beaufort_rivers_13rivs_nosections_chaflaradnudclm_7932171_subset_bed_his1thru5.nc:

bath: Ocean bathymetry in the model grid

bed_porosity: Porosity of each sediment layer in the seabed

bed_thickness: Thickness of each seabed layer

bstrcwmax: The maximum bed shear stress, from the combined wave- and current-induced bed shear stresses

bustrw: Wind-induced bed shear stress in the u-direction

bvstrw: Wind-induced bed shear stress in the v-direction

mud_05: Suspended sediment concentrations for unaggregated mud from the Colville River

ocean_time: Model time

Variables for KakAKgrd_shelf_big010_smooth006.nc:

angle: Angle between the grid’s horizontal (xi) dimension and east
