SedCas: Sediment Cascade Model

Source code for SedCas. For a detailed model description, please see Hirschberg et al. (2021)

How to install and run

Pyhton has to be installed to run the codes. To make sure it works correctly, it is easiest to install Anaconda and create an environment with the right packages from the .yml file. To this end, in a command-line interpreter, change the working directory to where you saved this project and run the following:

$ conda env create -f sedcas.yml

$ conda activate sedcas or $ source activate sedcas

To run an example:

$ python run.py

How to modify the model

If you want to modify the model or adapt it to your case, there are the following options:

• change parameters in the .par file
• change the climate input in the .met file
• add or change a module in module.py
• implement new modules into the model structure in SedCas.py
