The Early Medieval Fossa Carolina is the first hydro-engineering construction that bridges Central European Watershed. canal was built in 792/793 AD on order of Charlemagne and should connect drainage systems Rhine-Main catchment Danube catchment. In this study, we show for time, integration Airborne LiDAR (Light Detection Ranging) geoarchaeological subsurface datasets with aim to create a 3D-model Charlemagne’s summit canal. We used purged Digital Terrain Model reflects pre-modern topography. geometries buried cross-sections are derived from three archaeological excavations four high-resolution direct push sensing transects. By means extensive core data, interpolate trench bottom adjacent edges along entire course. As result, able maximum depth Carolingian calculate an excavation volume approx. 297,000 m3. Additionally, compute present dam remnants by data. Surprisingly, reveals only 120,000 m3 much smaller than computed volume. difference erosion anthropogenic overprint since 8th century AD.
