High-Resolution Digital Surface and Bathymetric Model for Duero River in Zamora

Álvaro Esteban-Muñoz provides a 1-meter resolution Digital Surface-River Bathymetry Model (DSRBM) for a 5.4 km urban reach of the Duero River in Zamora, Spain, including its 500-year floodplain. The model integrates airborne LiDAR with 33 field-surveyed bathymetric cross-sections and was validated using 3,407 terrestrial and 8,472 bathymetric control points.

Use Cases

• Build 2D hydraulic models in HEC-RAS or Iber using the 1-meter resolution DSRBM GeoTIFF for flood depth and extent simulation.
• Analyze underwater topography from the 33 bathymetric cross-sections stored in KMZ/Shapefile format to assess the impact of fluvial islands and weirs.
• Validate elevation model accuracy using the 3,407 ground control points from GNSS/IMU surveys across urban and agricultural areas.
• Create flood hazard maps by integrating the terrestrial LiDAR data and river bathymetry to reduce errors in flood risk assessment.

Strengths

• High spatial resolution of 1 meter for the composite DSRBM GeoTIFF.
• Extensive validation with 3,407 terrestrial and 8,472 bathymetric independent control points.
• Covers a 5.4 km river channel and its associated 500-year floodplain.
• Integrates multiple data sources: airborne LiDAR and 33 field-surveyed bathymetric cross-sections.

Limitations

• Spatial coverage is limited to a specific 5.4 km urban reach in Zamora, Spain.
• Dataset is static with no stated temporal range or update frequency.
• Requires specialized GIS (e.g., QGIS) or hydraulic modeling software for full utilization.
