Short summary

We presented NAAC, a high-resolution, two-decade simulation of coastal hydrodynamics using the 3D unstructured-grid model SCHISM (Semi-implicit Cross-scale Hydroscience Integrated System Model; v5.11.0). This model seamlessly integrates simulations from the North American Atlantic coastal ocean to tidal tributaries and wetlands. By bridging the gap between large-scale regional ocean models and fine-scale shallow water systems and intertidal zones, this work helps fill observational gaps and provides valuable insights into studies like saltwater intrusion.
