Understanding the mechanisms that drive interactions among Earth surface processes and tectonic/climate forcing, as well as their mutual feedback relationships, is the topic of a wide scientific community. Nonetheless, these interactions and feedback relationships can be approached at different spatio-temporal scales, depending on the final research purposes.
When focusing on the hazardous phenomena, related to tectonics (e.g., earthquakes and volcanic events), gravity (landslides), and climatic events, the complex interaction between regional and local tectonics (regional uplift/subsidence and faulting), morpho-climatic factors, and rock types must be taken into account. Intermontane basins are important landscape units generally developed at the intermediate spatio-temporal scale, which implies the morpho-evolutionary processes to be sensitive to both tectonic and climatic inputs. This makes intermontane basins as key sites that record differences in both erosional/depositional and gravitational slope processes related to drainage evolution and slope dynamics in response to local and regional base level changes and to differential rock uplift. At this spatio-temporal scale, multidisciplinary approaches among geomorphologists, sedimentologists, Quaternary, structural and engineering geologists is promising for the development of qualitative/quantitative tools to decipher the influence of tectonics in shaping landscapes and to define tectonic histories through landscape analysis.
Given the rapid growth of new tools and perspectives (e.g., quantitative and object-based geomorphology, geodesy, improved geochronological techniques, analytical algorithms, numerical modeling, quantitative stratigraphy), this session is aimed at presenting and promoting multidisciplinary and innovative studies on intermontane basins in different tectonic contexts of the world. Importance will be given to advanced and original works including: morpho-stratigraphic characterization and dating of geomorphic markers; development of geostatistical and geomorphic tools to detect active tectonic structures; calibration and integration of quantitative methods to estimate uplift, erosion and deposition rates at the intermediate time scale; analysis of the effects of morpho-evolutionary rates on large slope instability events; landscape evolution models.
