The prospection of (geo-)archaeological sites yield important knowledge about the concept and utilisation pre-historical historical infrastructure. satisfactory conduction classical methods like archaeological excavations or geoarchaeological vibra-coring might be challenging in case large difficult underground conditions. This is particularly problematic wetlands featuring a high groundwater table compaction rates organic layers. In this study, we provide an alternative non- to minimal-invasive exploration approach discover hydro-engineering structures for artificial water supply surrounding Carolingian summit canal South Germany. Early Medieval Fossa Carolina was intended 792/793 CE bridge Central European watershed between Rhine-Main Danube catchments. As constructed as canal, at highest levels seemed very likely even obligatory. order explore these obligatory features, use wide range on-site off-site tools spatial hierarchical way. Our includes large-scale SQUID magnetic survey sighting maps. Furthermore, integrate high-resolution direct push colour logs, subsequent small-scale stratigraphical verification sedimentological analyses. related depth models two pronounced linear anomalies that represent potential inlets North-Eastern Northern Sections canal. I) Section, 14C dating no evidence feature but reveal natural lenticular structure Holocene age. II) anomaly Section can excluded with probability well. Here, vibra-coring, comparison historic map gravel road. Thus, have nicely verified information prove inlet from Swabian Rezat River contradicts assumptions former studies.
