Output Files

The model supports multiple output modes controlled through the output block in the config.yaml file. Output behavior is governed by the flag, and additional options depend on which output strategy is selected. All outputs are saved as NetCDF files. Outputs are generated for each time chunk specified based on the runoff input options.

Configuration Options

output:
  flag: 1                            # 0 = no output, 1 = by stream level, 2 = specific links
  level: 4                           # Required if flag = 1
  link_list_filename: "mylinks.csv"  # Required if flag = 2
  series_filepath: "/output/mytimeseries"
  snapshot_filepath: "/output/snapshot"

Option Definitions

Flag = 0: No time series outputs

• No time series will be saved. Snapshots will be saved.
• Useful for benchmarking, debugging, or for spin up of initial conditions.

Flag = 1: Constant Initial Value

Flag = 2: Constant Initial Value

Snapshots

Restart files (called "snapshots") are generated during each write out after a chunk of runoff has been processed. These can be used to restart simulations by specifying the netCDF option in the Initial Conditions options.
