ModeROff

Mode for runoff model

The runoff model to use

  • 0 = default model (spatially constant runoff)
  • 1=Spatially random runoff coefficient using spatial state in the RST2 file.
  • 2=Spatially varying rainfall (input in runoff model file)
  • 3=Regions of spatially varied hydrology model (input in runoff model file).

Runoff 

 InputFile: Runoff Model

Runoff Model File

  • A supplementary file from which runoff data is read in the more advanced runoff models.

 ModeDir

 Mode for Drainage Directions Model

 The drainage direction model to use

  • 0=default model (drainage in the the steepest downslope direction)
  • 1=as for default except channels must drain into channels
  • 2=Permanent contour banks
  • 3=Drainage directions not allowed to change during run.
