ARC Input File Arguments - MikeFHS/automated-rating-curve GitHub Wiki

Here is a table explaining what each of the different arguments do when you run ARC. This is a work in progress.

Parameter String	Required/Optional	Input Type	Default Value	Description
DEM_File	Required	str	—	Path to the DEM raster file
Stream_File	Required	str	—	Path to the stream raster file
LU_Raster_SameRes	Required	str	—	Path to the land use raster file that is the same resolution as the DEM_File
LU_Manning_n	Required	str	—	Path to the Manning’s n text file
Flow_File	Required	str	—	Path to the input flow file that ARC will use to create the VDT Database and Curvefiles
Flow_File_ID	Required	str	—	Field ID for the ID for the streams in the Flow_File that corresponds to the values in the Stream_File
Flow_File_BF	Required	str	—	Field ID for base-flow in the Flow_File
