Plio-Pleistocene Landscape Evolution of the Turano River Basin (Central Apennines, Italy): Insights from Continental Deposits’ Analysis and Drainage Network Development

Le résumé fourni par la source

Quaternary continental deposits record spatio-temporal changes of the landscape and offer insights for drainage network analysis and paleoenvironmental reconstructions. This paper focuses on the Turano River, a left tributary of the Velino River, which flows in the southwestern Abruzzo area at the boundary with Lazio Region. Its basin preserves lithological and morphological field evidence particularly suitable for reconstructing the long-term geomorphological evolution of the Central Apennines and the drainage network development. In detail, the Turano River was investigated through a drainage basin-scale analysis incorporating morphometric analysis, field mapping, continental deposits analysis, and integrated drainage network analysis. This approach allowed us to define a drainage network reversal process, clearly highlighted by the spatial arrangement of continental deposits, spanning from Upper Pliocene to Holocene. The results also indicated tectonic activity as the main factor driving incision and river inversion processes. The work contributes to identifying and describing the main steps of the Quaternary landscape evolution of this mountainous catchment and its morphoneotectonic framework. Therefore, it could represent a methodological tool for multidisciplinary studies in similar mountainous catchments to support any territorial planning activity, from large infrastructure localization (i.e., artificial dams) to sustainable land management.
