The archaeological evaluation of landscapes in the framework developer-led archaeology is often based on extensive trenching programmes complemented with auger surveys wetland environments. During a 90 ha polder site north-west Belgium, mobile multi-receiver electromagnetic induction (EMI) survey was used as main prospecting technique. use allowed to map entire study area at very fine resolution (over 25 measurements per m2). Incorporating EMI instrument enabled measuring apparent electrical conductivity (ECa) and magnetic susceptibility (MSa) four different soil volumes simultaneously each location. detailed maps provided insight into geomorphological features site. Among detected structures were large medieval farmstead, palaeoriver system number military remains from World War I (WWI). vertical discrimination potential added facies changes, which modeling palaeolandscape helped determining depth features. MSa gave additional WWI structures. In this paper, we give an overview possibilities combining multiple ECa for interpreting variability together example information gathered data. More generally, diverse geoarchaeological research demonstrated.
