| description | <p>The French Upper Rhine alluvial plain is characterized by
a complex system of paleochannels inherited from Late Glacial to Holocene
fluvial dynamics of the Rhine and Ill river systems, among other smaller
rivers. These paleochannels represent valuable archives for understanding
and reconstructing the fluvial and landscape evolution of the area. However,
the Holocene temporal trajectories of the paleochannels, in response to a
range of environmental changes, remain poorly understood. This study
presents a detailed and systematic mapping and characterization of an
extensive network of paleochannels spanning the entire width (19 km) of a
reach of the central French Rhine plain. Based on qualitative and
quantitative lidar analysis, field investigations, and provenance
investigations of paleochannel infill sequences, five distinct paleochannel
groups (PG 1 to PG 5) were identified in the study area. These paleochannel
groups differ considerably regarding their channel patterns, morphological
characteristics, and sedimentary sources of the infilling sediments. The
interpretation of the different datasets indicates that the development of
these different paleomorphologies is attributed to significant changes in
hydro-geomorphodynamic processes in the area during the Holocene, especially
lateral migrations of the Rhine and Ill rivers. The findings reported here
are promising and will have significant implications for reconstructing the
long-term (Late Glacial to Holocene) evolution of the Upper Rhine fluvial
hydrosystem in response to various controlling factors.</p> |
