The data include model setup files (Delft3D-FLOW) and output results supporting research on the evolution of the Arctic continental shelves. Experimental setup includes 1000-year morphodynamic evolution simulations of two representative cross-shelf sections (located near Harrison Bay, AK, and Flaxman Island, AK) under two wave climates each ("Present-Day" waves and "RCP8.5" waves). Wave climates were extracted from a publicly available datasets (Casas-Prat et al., 2018). Annual time series were constructed for the Alaskan Beaufort shelf over a hindcast period from 1979-2005 and RCP8.5 projected period between 2081 and 2100 (Casas-Prat et al., 2018). The 1979-2005 wave hindcast is hereafter referred to as present-day waves, and the projected 2081-2100 dataset is referred to as RCP8.5 waves. A representative Beaufort Sea storm was then applied to the four output shelf profiles to evaluate the impact of shelf geometry on wave attenuation.
