River network characteristic parameters data and landscape evolution model code

This archive comprises two files utilized in the research conducted by Meng et al. The first file contains the code (.m) for simulating geomorphic evolution, while the second file contains the data (total.xlsx) for three measurements. Specifically, the code enables the rapid iteration of steady-state terrain elevation data for various initial slopes (%) and net rainfall intensities (mm/year). The river networks vector data is generated by the hydrological analysis tool, based on the aforementioned elevation data. The river networks characteristic parameters data (total.xlsx) can be derived by calculating the vector data with ArcMap software. These parameters include drainage area increments along mainstreams, stream course irregularity, and tributary junction angles.
