A-level information is printed each time a time-dependent boundary condition is specified. The information is directed to output file A_LEVEL.OUT.
Value
imports A_LEVEL out with tidy column names and saves metainformation in attributes 'meta_general' and 'meta_units'
- time
Time, t, at current time-level [T]
- sum_r_top
Cumulative potential surface flux [L] (infiltration/evaporation: -/+)
- sum_r_root
Cumulative potential transpiration [L]
- sum_v_top
Cumulative value of the actual surface flux [L] (infiltration/evaporation: -/+) [-]
- sum_v_root
Cumulative value of the actual transpiration [L]
- sum_v_bot
Cumulative value of the bottom boundary flux [L] (inflow/outflow: +/-)
- h_top
Pressure head at the soil surface [L]
- h_root
Mean value of the pressure head in the soil root zone for which Beta(n)>0 [L]
- h_bot
Pressure head at the bottom of the soil profile [L]
- a_level
A-level number (current variable boundary condition number) [-]
