“…The topsoil and other Late Holocene estuarine floodplain sediments were combined into one lithostratigraphic unit, because it is impossible to map the morphology of geometrically complex and small buried estuarine geomorphic features (tidal gullies, crevasses, …), given the distance between the CPT‐Es. Verhegge, Saey, Laloo, Bats, and Crombé (2017), Jongepier, Wang, Missiaen, Soens, and Temmerman (2015); Saey, Verhegge, et al (2016) have illustrated that the Late Holocene (embanked) estuarine floodplain paleolandscape of the study region is better mapped using near‐surface geophysical survey and/or historic maps than primarily through CPT‐E.…”

“…In 2015, a 150 ha large area was investigated in context of a development‐led geoarchaeological evaluation of Holocene sediment layers and possible (post‐)medieval embankment structures (Saey, Laloo, et al 2016). The results of electromagnetic induction survey were published by Saey, Verhegge, et al (2016), but only mapped the Holocene paleotopography and did not incorporate the underlying Late Glacial paleolandscape. Core samples and CPT‐Es were collected into the Late Glacial coversand but the research focused on the Holocene sediment sequence.…”

Late Glacial coversand landscapes are important archives of environmental change during the Pleistocene–Holocene transition as well as of Final Paleolithic human adaptation to these changes. However, extensive reconstruction of these landscapes is hampered by the fact that they are often preserved best when covered with later eolian, alluvial and/or marine sediments. These paleolandscapes are generally mapped by means of manual or mechanical coring to date, which is rather expensive and labor‐intensive. This study aims to develop a more efficient methodology to map paleolandscapes buried within the coversand and below Holocene floodplain deposits, using a case study in NW Belgium. Electric cone penetration testing is established as a primary technique for mapping the paleotopography of thin organic rich layers within the coversand, in combination with core sampling for lithostratigraphic correlation and validation. Radiocarbon dating and pollen analyses are used to investigate the chronological and biostratigraphic context, respectively. The results reveal the paleotopography of three undulating organic rich stabilization surfaces within the coversand, which were formed from the GI‐1d to GI‐1a. These paleosurfaces provide valuable contexts for studying Final Paleolithic archaeology in the coversand region specifically, but the developed methodology is applicable to Paleolithic archaeology in general.

“…By iteratively modelling the integrated electrical conductivity up to 1.8 m below the soil surface, a profile distribution of this conductivity was calculated. It should be taken into account that only larger variations in ECa can be determined using this methodology and that the output is a smooth model of the stratigraphy (Saey et al, ).…”

During the 10th to 13th centuries, the rural settlement landscapes of the County of Flanders underwent major changes. Complex interactions between urbanization, growing comital power, demographic changes and rural development formed the basis for intensified reclamations of the landscape. Based on historical research, the ab nihilo plantation of grouped rural settlements by the counts and other landlords played an important role in the organization and systematization of these reclamations. To date, however, archaeological attention for these grouped settlements is scarce, mainly due to Flanders' build‐up and urbanized character. This article describes the renewed cross‐disciplinary landscape archaeological research at the site of the lost village of Nieuw‐Roeselare (northern East Flanders), which was the first medieval village to be partly excavated in Flanders between 1967 and 1979. Believed to have been planted in 1241 and lost to floods in 1375, little is known historically about the site nor does the modern‐day polder landscape show any remnants of a former settlement. Now, a large‐scale cross‐disciplinary prospection comprising 35 ha of frequency‐domain multi‐receiver electromagnetic induction (EMI), oblique aerial photography, augering, pseudo‐two‐dimensional tomography and site specific artefact‐accurate field walking, allowed to define the settlement's full extent, clarify its geographical context and identify its morphology as a planted settlement in the context of the medieval landscape reclamations.

“…Furthermore, despite the availability of inversion software using FS forward models the CS forward model is still commonly used (e.g. Huang et al, 2016;Saey et al, 2016), despite its inherent simplifications. Lastly, there has also been interest in calibrating EMI measurements to account for factors relating to operation setup and permit the easier convergence of data.…”
