| Abstract |
During an archaeological excavation in the Scheldt Valley, a geomorphological study allowed a better understanding of the sedimentary dynamics during the Early Holocene. The data provide evidence of a fluvio-lacustrine environment established at the Weichselian/Holocene transition which disappeared with the intensification of pine forests. The latter probably contributed to the lowering of groundwater, but also to the increase in the frequency and extent of natural forest fires leading to a period of slope instability and a renewal of alluvial dynamics. The emergence of mixed forests less prone to fires ultimately leads to the formation of alluvial swamps. |
