Supplementary data and codes for Quaternary landscape evolution of Apennines peri-Adriatic belt: insights into climate and tectonics from the fluvial record

This repository contains all scripts, datasets, and analysis workflows used to produce Figures 5, 6, and 7 of the following paper: Ruscitto, V. , Delchiaro, M. , Richard, M. , Iacobucci, G. , Piacentini, D. , Troiani, F. , & Della Seta, M. (2026). Quaternary landscape evolution of Apennines peri-Adriatic belt: insights into climate and tectonics from the fluvial record. Science Advances. https: //doi. org/10. 1126/sciadv. aec5376 All the analysis were performed using TopoToolbox 3 (Schwanghart and Scherler, 2014) and the Topographic Analysis Kit (TAK) by Forte and Whipple (2019). The repository is organized as follows: ├── figure5/│ ├── aso/│ │ ├── data/│ │ └── asoₚrojₛcript. m│ ├── tenna/│ │ ├── data/│ │ └── tennaₚrojₛcript. m│ └── tesino/│ ├── data/│ └── tesinoₚrojₛcript. m│├── figure6/│ ├── codefigure6. m│ └── DATA. m│├── figure7/│ ├── asoₚrojₛcript. m│ ├── tennaₚrojₛcript. m│ └── tesinoₚrojₛcript. m│└── README. txt figure5/ Contains three subfolders for each river (Aso, Tenna, Tesino). Each folder includes the scripts and datasets used to reproduce all analyses and visualizations presented in Figure 5. Each river basin folder (aso, tenna, tesino) contains: data/ Shapefiles of terrace treads, strath surfaces, and the Fermo Formation High‑resolution LiDAR Digital Terrain Models (DTM) from the Ministero dell’Ambiente e Sicurezza Energetica (MASE): https: //sim. mase. gov. it/portalediaccesso/mappe/#/viewer/new The Relative Elevation Model (REM) computed following the procedure described in Dilts et al. (2010) *ₚrojₛcript. m (asoₚrojₛcript. m, tennaₚrojₛcript. m, tesinoₚrojₛcript. m) MATLAB scripts performing the projection of terrace treads and strath surfaces along the river profile, and generating the boxplots of the relative elevation values for terrace treads, strath surfaces, and the Fermo Formation. figure6/ Contains the scripts and data used to generate Figure 6, including: codefigure6. m Main MATLAB script plotting the complete set of available terrace ages and their probability densities against key climatic and sea‑level reference curves for the last 500 ka. DATA. m Input datasets required for running the script (e. g. , literature datings, river outlets, δ¹⁸O curve, river distances and relative sea level). figure7/ Contains the scripts used to generate Figure 7, integrating the results from the three river basins: asoₚrojₛcript. m, tennaₚrojₛcript. m, tesinoₚrojₛcript. m Scripts performing the incision‑rate modelling for each river.
