The semi-automatically removal of these features and artefacts was based on topographical vector data, visual interpretations and slope analysis. Ultimately two DEM's are constructed (1) a TIN (Triangulated Irregular Network) model whereby the inherent large file format restricts the usability to large scale and (2) a grid model which can be used for small-, medium-and large-scale applications. Both datasets are used as an image that is interpreted using ancillary data from historical sources. Its usefulness is illustrated in a case of field pattern and micro-field topography. Starting from this DEM, the approach of this landscape historical study is mainly retrogressive, i.e. starting from the landscape structures and elements that are still present in the contemporary landscape and moving into the past.

Understanding palaeotopographical variability forms the basis for understanding prehistoric societies.Alluvial and lacustrine environments, in particular, are key areas with both a high archaeological and palaeoecological potential. However, the often deep stratification of these sites, the high water table and the complex sedimentological variations can hamper a detailed reconstruction of the spatial relationship between prehistoric settlement and their environment. Combining different remote and proximal sensing techniques and coring data, can offer detailed insight into such landscapes. More specifically, the integration of mobile geophysical methods allows the collection of unprecedented continuous information on large-scale palaeolandscape variability. In this study we present a combined approach in order to map and model prehistoric landscapes and river systems in and around a Late Glacial palaeolake in north-western Belgium. Based on filtered and unfiltered digital elevation models, a survey area of 60 ha was selected, in which detailed mobile multi-receiver electromagnetic induction survey was conducted. The results allowed for the delineation of palaeochannels in the area and enabled modelling the depth of these features in the survey area, providing insight into their flow characteristics.14 C sampling enabled the dating of the evolving river system to the transition between the Late Glacial and the Early Holocene. Through additional coring, this river system could be traced further through the palaeolake area. Based on these results a detailed reconstruction was made of the palaeotopography that harboured the Final Palaeolithic andEarly Mesolithic occupation of the study site.
