The repository contains four archive files as a supplement for the journal article "Old orogen - young topography: lithological contrasts controlling erosion and relief formation in the Bohemian Massif" (https://doi.org/10.5194/egusphere-2024-3256) 01_Tables.zip: the archive contains tables with erosion rates of the individual catchments, their topographic metrics and the degree of correlation between catchment-wide erosion rates and topographic metrics. 02_Movie.zip: the archive contains serval movies as supplement to Fig. 10 and show the time-dependent evolution of the topography, bedrock properties and erosion rates in the study region. 03_Figures.zip: The archive contains a figure showing the geophysical relief and the drainage network color-coded for ksn, which serves as a supplement to Figure 1. Furthermore, figures are provided for the morphometric analysis of each of the 20 catchments studied. 04_Numerical_Model.zip: the archive contains all files and required input data of the time-dependent model for describing landscape evolution in the area of the Bohemian
