Mooring Data for Validation To apply this model framework to other years, users may access publicly available data from the following sources: - NOAA data for tidal boundary forcing and meteorological conditions (NOAA, 2024), accessible via the NOAA data download tool (Clunies, 2023) - USGS datasets for river discharge analysis and boundary forcing (USGS, 2024; USGS, 2025), using the USGS dataretrieval tool (Hodson, 2023); - Water level data from NOAA (NOAA, 2024), USACE (USACE, 2025), and USGS (USGS, 2024) used for model calibration and validation.
