This dataset contains data for the research on Downscaling sea-level rise effects on tides and sediment dynamics in tidal bays. There are seven scenarios included: baseline (2009); SLR 0.25m, 0.50 m, 0.75 m, 1.0 m, 1.5 m, and 2.0 m. In each scenario, there are 12 netcdf file, each contains the simulation of one month with the hourly temporal resolution. The variabls can be extracted include water elevation and barotropic current velocity on a mesh grid of 300 m * 300m.
