Command Line Options

-w filename (necessary)	Name of the worldfile
-t filename (necessary)	Name of the tecfile
-r filename	Necessary for explicit routing - if "-r" not used then TOPMODEL routing will be used
-b optional ID	Necessary for basin output, the ID is used to specify individual basins, no ID implies all basins
-h optional ID	Necessary for hillslope output, the ID is used to specify individual hillslopes, no ID implies all hillslopes
-z optional ID	Necessary for zone output, the ID is used to specify individual zones, no ID implies all zones
-p optional ID	Necessary for patch output, the ID is used to specify individual patches, no ID implies all patches
-c optional ID	Necessary for stratum output, the ID is used to specify individual strata, no ID implies all strata
-g	"-g" specifies dynamic version of RHESSys, if "-g" not used, then RHESSys defaults to static mode.
-s value value <optional value>	Sensitivity parameters (-s option must be followed by two values and a third optional value). Values specify three multipliers which are used to scale specific variables initialized in the worldfile. The first required value, (a sen1) designates m, the decay of hydraulic conductivity with depth, the second required value, (a sen2) designates K, hydraulic conductivity at the surface, and the third optional value, (a sen3) designates soil depth. In the current implementation, the m, K, and soil depth parameter values initialized for all patches in the worldfile are multiplied by 1) a sen1 2) a sen2 and 3) a sen3 respectively during a simulation. User must modify code to permit calibration based on other parameters.
-gw value value	Sensitivity parameters (switch must be followed by two values) Specifies two multipliers which are used to scale specific variables. The first value is the multiplier of the sat_to_gw_coeff in the hillslope default file (representing the amount of water moving from the saturated store to the groundwater store). The second value is the multiplier of the gw_loss_coeff in the hillslope default file (representing the amount of water moving from the groundwater store to the stream).
-pre character string	Prefix to be used for output files
-st year month day	Start date (switch must be followed by the date), this overrides the start date used in the worldfile
-ed year month day	End date (switch must be followed by the date), this overrides the end date used in the worldfile
-snowdistb value	If this flag is used RHESSys will run snow redistribution for each patch. To use this option there must be an additional state variable at the patch level in the worldfile. An optional tolerance parameter can be included with the command line to limit change in the water balance associated with snow redistribution.
-th value value	The first value is the threshold value for saturation deficit (it allows output of the number of days patch saturation falls below the threshold (water stress days), which can be used an annual water stress index). The second value is the threshold value for streamflow (it allows output of the number of low flow days below some set threshold). The -th option is meant to be used with yearly output - which requires the print_yearly_on event in the tecfile.
-tmp value	Sensitivity analysis of soil N decay rate
-dor value	Sets DON loss rate as a specified proportion of total mineralization, with DOC rate set using appropriate DON/DOC ratios (e.g. -dor 0.03 sets the DON loss rate as 3% of total mineralization)
-old	Read a worldfile from the previous version of RHESSys and set any new world state variables to defaults (in this case Ksat_vertical to 1.0), note any world_state output will be a ver5.4 compatible worldfile
-vgsen value value value	Multipliers which alter vegetation specific parameters. The first value multiples specific leaf areas. The second value multiplies the ratio of shaded to sunlit leaf area. The third value is a multiplier used only with the Dickenson algorithm of carbon allocation (set at the epc.allocation_flag variable in the vegetation definition file). It changes the allocation of net photosynthate sensitivity based on the current LAI. If not using the Dickenson strategy of carbon allocation (i.e. using Waring or default Constant strategies), set third value to 1.0. (i.e. -vgsen 1.0 2.0 1.0)
-csv	Produce comma delimited output (this overrides previous use of output_csv_... in the tec file
