MESH - A Community Hydrology - Land Surface Model


Skip to end of metadata
Go to start of metadata

Control flag to describe the active land surface scheme and routing routine. The flag is added to the list of control flags in MESH_input_run_options.ini.

Default behaviour

The default configuration of the model, if the flag is assigned the 'default' option or otherwise omitted from MESH_input_run_options.ini, is to run with CLASS 3.6 as the land surface scheme and WF_ROUTE as the routing routine.

MESH_input_run_options.ini
##### Control Flags #####
----#
    1 # Number of control flags
RUNMODE                  default

Examples

Different options and processes may have different data and/or parameter requirements, even if in the same group. For now, refer to the notes and options in MESH_parameters_hydrology.ini (2.0) for the parameters required for WF_ROUTE and RTE...

To run CLASS 3.6 with RTE:

MESH_input_run_options.ini
##### Control Flags #####
----#
    1 # Number of control flags
RUNMODE                  runrte

To run SVS with RTE:

MESH_input_run_options.ini
##### Control Flags #####
----#
    1 # Number of control flags
RUNMODE                  runsvs runrte

Options

Land Surface Scheme (LSS) and tile processes

Only one of these options should be specified. If multiple options from this group are specified, only the last will take effect. An option from this group can be paired with an option from another group.

OptionDescription
runsvsEnable SVS; disable CLASS 3.6
runclassEnable CLASS 3.6; disable SVS
nolssDisable CLASS 3.6 and SVS; disable 'tile' processes, reading in climate data, and writing basin water and energy balance output files

Routing routine and grid processes

Only one of these options should be specified. If multiple options from this group are specified, only the last will take effect. An option from this group can be paired with an option from another group.

OptionDescription
runrteEnable RTE; disable WF_ROUTE
norouteDisable WF_ROUTE and RTE; disable 'grid' processes, channel routing, AUTOCALIBRATIONFLAG, and streamflow and reservoir output files

Default and diagnostic configuration

These options override all other options. If both options are specified, only the first will take effect.

OptionDescription
defaultEnable CLASS 3.6 and WF_ROUTE; disable SVS and RTE
diagnosticDisable 'tile' and 'grid' processes; reading in climate data and writing output files remain active
