Supplemental data to: Hillslope-controlled incision thresholds shape mountain range topography

The following data set includes supplemental data to the publication: "Hillslope-controlled incision thresholds shape mountain range topography". The data includes (1) grain size data from streams in the Central and Eastern Cordillera from hand and drone pebble counting, (2) shape-files delineating stream channels used for channel width calculations, and (3) the data and code used for the Stochastic Threshold Incision Modelling (STIM).
