| The NRSOILLAYEREADFLAG control flag controls the number of layers to read from MESH_parameters_CLASS.ini or MESH_parameters.txt when reading soil-related parameters and initial values. |

Behaviour without this option (NRSOILAYEREADFLAG 0)
Without activating NRSOILAYEREADFLAG, three values for each soil-related parameter and initial value field are required in MESH_parameters_CLASS.ini or MESH_parameters.txt, regardless of the number of soil layers defined in MESH_input_soil_levels.txt:
...
| Info |
|---|
| The mapping of these fields from the lowest parameterized layer to lower layers happens automatically inside the MESH code. This is exactly the same process that occurred in MESH prior to the addition of the NRSOILAYEREADFLAG control flag. |
NRSOILAYEREADFLAG 1
When NRSOILAYEREADFLAG is activated with option 1, no mapping is done and the same number of values must exist for the soil-related parameters and initial values in MESH_parameters_CLASS.ini as the total number of soil layers (NSL) defined in MESH_input_soil_levels.txt.
...
Example
NRSOILAYEREADFLAG is activated with option 1 in MESH_input_run_options.ini:

NRSOILAYEREADFLAG <n>
When NRSOILAYEREADFLAG is activated with an option > 3 but less than the total number of soil layers (NSL), a similar mapping is done as when NRSOILAYEREADFLAG is disabled, but the lowest parameterized layer used to assign values to lower layers is the layer specified as <n>.
| Info |
|---|
If <n> is set equal to NSL, the the option is equivalent to "NRSOILAYEREADFLAG 1". |
...
Example
NRSOILAYEREADFLAG is activated with option <n> in MESH_input_run_options.ini, where <n> is set to 4 to read values for 4 soil layers:
...
| Code Block |
|---|
|
do j = 5, NSL
sand(:, j) = sand(:, 4)
clay(:, j) = clay(:, 4)
orgm(:, j) = orgm(:, 4)
tbar(:, j) = tbar(:, 4)
thlq(:, j) = thlq(:, 4)
thic(:, j) = thic(:, 4)
end do |
Verifying the state of NRSOILAYEREADFLAG
| Info |
|---|
| The following only applies if CLASS is activated as the HLSS in the model. The following information is not printed for runs using SVS as the HLSS. |
The state of NRSOILAYEREADFLAG can be inferred from the CLASS prognostic state summary printed to MESH_output_echo_print.txt at the end of a normal simulation.
If NRSOILAYEREADFLAG is disabled or if only 3 layers are defined in MESH_input_soil_layers.txt, only three values for the respective fields are printed to the file:

Considerations
Decreasing the number of soil layers in an existing setup with "NRSOILAYEREADFLAG 1"
...
This cascade would continue until no more numbers could be read from the file, when the model would again stop with a 'read'-related error.
