    • Patapsco Terrain models

    Metadata Updated: September 17, 2025

    Terrain models representing river channel and terrestrial surface elevations were developed for use in 2D hydraulic modeling with HEC-RAS software. Channel bed elevations were determined from cross-sectional field surveys (Seneca Creek and Patapsco River) or manual corrections of the LIDAR data (Patuxent River and Little Gunpowder Falls) and integrated with the terrestrial LIDAR data.
