Abstract

In order to investigate the impact of catchment response time on sediment flux, the AA. integrated a spatially-lumped numerical model PaCMod, with new routines simulating the evolution of landscape morphology and erosion rates under tectonic and climatic forcing. They subsequently applied the model to reconstruct the sediment flux from a tectonically perturbed catchment in central Italy. Finally, they coupled their model to DeltaSim, a process-response model simulating fluvio-deltaic stratigraphy, and investigated the impact of catchment response time on stratigraphy, using both synthetic scenarios and a real world system (Fucino Basin, central Italy). Their results demonstrate that the differential response of geomorphic elements to tectonic and climatic changes induces a complex sediment flux signal, and produces characteristic stratigraphic architectures and shoreline trajectories
