Quantifying the anthropogenic forcing on soil erosion during the Iron Age and Roman Period in southeastern France
چکیده انگلیسی

This study combines a traditional qualitative description of sedimentary units with a quantitative sediment budget approach to document the colluvial and alluvial sediment dynamics in the Valdaine region (Drôme, France) from the Iron Age to the early medieval period (700 BC–900 AD). Three transects through colluvial and alluvial deposits are discussed in detail to demonstrate the way in which absolute dating techniques and archeological evidence are combined to establish a stratigraphic framework. This framework is applied to 16 sites and further combined with an existing sediment budget to quantitatively reconstruct the catchment-wide sedimentary evolution. Results show large variations over time in sediment deposition: a first phase from 700 to 400/300 BC, followed by an incision phase between 300/200 BC and 100/50 BC, an unprecedented peak in deposition during the Roman period (100/50 BC–450 AD), with continued but decreased deposition from 450 to 900 AD. These results show how sediment deposition relates to increased population density and anthropogenic land use on a timescale of a few centuries. The analysis indicates important erosion and deposition phases during the Roman period, considered to be a warmer period (Roman warm period). A relation to particular regional climate variations could not be discovered, possibly because of the temporal resolution of the sedimentological data that still fail to identify events lasting a few decades to a century.
