Model Constants and Miscellaneous Parameters¶
The VIC model requires the specification of many model parameters to run. While some parameters are spatially distributed (e.g. soil, vegetation, or snowbands), others are more appropriately held constant across the model domain.
Model Constants and Parameters¶
Some model constants and model parameters need to be changed more frequently. VIC-WUR supports this through the use of the optional
CONSTANTS file. The path to this file should be specified in the global parameter file.
The table below lists the constants available for manipulation via the
CONSTANTS file. Descriptions will be added later or as needed.
|DAM_ALPHA||Preferred dam maximum storage fraction||fraction||0.85|
|DAM_BETA||Dam correction exponent||-||0.6|
|DAM_GAMMA||Dam correction period||days||5|
|Ksat_expt||Paddy irrigation saturated conductivity exponent||-||0.33|
|Wfc_fract||Field capacity as fraction of critical moisture content||fraction||0.8|
|NONRENEWABLE_LIMIT||Non-renewable withdrawal limit (depth)||mm||Inf|
