SIBERIA: Advanced Parameters

The parameters controlling the internals of SIBERIA. These parameters should never be changed and are only here to allow them to be changed in the unlikely event that future developments in SIBERIA require this change. This section also includes some models for SIBERIA that are either poorly developed, incompletely implemented or tested or research in progress.

 Explanation

 5

ModeI 

Mode for initial elevations in blank runs

  • Default value=0 which yields spatially uniform uplift

 7

 ModeSed

 Mode for Sediment transport solver

  •  Current default value is 4. ModeSed=5 no longer recommended as 4 is slightly more accurate.

 10

ModeRn

 Mode for random perturbation solver

  • Default=0; no random perturbations
  • ModeRn=1: 'Spatial' multiplies b1
  • ModeRn=1: 'Spatial' multiplies b5

 15

ModeMC 

Mode for Monte-Carlo risk assessment solver

  •  Default=0

 16

 DirReg

 Averaging region for drainage directions solver

  •  Default=1, See Hancock (1998) PhD thesis.

 25

 FactMx

 Maximum value for FACTOR in fluvial sediment solver

  •  Default=1

 26

 FRanMn

 Mean of perturbations in random model

  •  Default=0

 28

 YFix

 The CIF for fixed Z points in the fluvial sediment solver

  •  Default=1

 29

 FRanCV

 CV of perturbations in random model

  •  Default=0

 30

 b3sds

 SD of short term variation in runoff rate

  •  Default=0

 31

 b3sdl

 SD of long term variation in runoff rate

  •  Default=0

 35

 FRanZ

 SD of randomisation in the initial elevations in blank runs

  •  Default=0

 48

 YHold

 YHold threshold in the CIF switching relationship

  •  Default=0.1
