Calculate the integrated surface water discharge from an elevation map and imposed precipitation, obtaining the steady-state configuration.

• Clone the landflow repository

• Compile the code in the landflow/ directory:

  make all
  

• Unzip the ETOPO1_SouthAmerica.xyz.zip file:

  unzip ETOPO1_SouthAmerica.xyz.zip
  

• Run ./extract_flow in the same folder with ETOPO1_SouthAmerica.xyz file.

• Run ./fluvial_Qr to obtain the surface water discharge.

• View the map with python create_Qr_map.py
