Since the early 1990s, excavations of a protohistoric lakeside settlement in the Korça basin carried out by a French-Albanian team have induced geomorphological and palynological studies about the sedimentary records of Lake Maliq and Lake Ohrid. Past water-level fluctuations of Lake Maliq were reconstructed using changes in the lithology (Digerfeldt, 1986; Magny, 2007) observed along a 150 m-long core transect from the tell of Sovjan to the lake basin. The sediment sequence of Lake Maliq allows to distinguish a series of centennial-scale high and low lake-level events which punctuated the Holocene period. We compare these results with those obtained by a multi-proxy approach on sediments of the bottom of Ohrid Lake.
To discuss the link between human settlement and environmental changes, we made a 3D model of the Holocene deposit from the lake. For this we used geomorphological mapping, excavation data, numerous core logs and AMS radiocarbon datings. SRTM DEM data, after DGPS control, were connected to a GIS including all geological and archaeological information. We obtained 4 reconstructions of the Maliq palaeo-lake during the late glacial times (around 14000 BP), the Early Neolithic (around 9000 BP), the Middle Bronze Age (around 4500 BP) and during Roman times (around 2000 BP), as well as a map of the thickness of sediments above potential archaeological layers.
