| 9 | !>\BRIEF This module computes the soil moisture processes on continental points. |
|---|
| 10 | !! |
|---|
| 11 | !!\n DESCRIPTION : contains hydrol_main, hydrol_initialize, hydrol_finalise, hydrol_init, |
|---|
| 12 | !! hydrol_var_init, hydrol_waterbal, hydrol_alma, |
|---|
| 13 | !! hydrol_snow, hydrol_vegupd, hydrol_canop, hydrol_flood, hydrol_soil. |
|---|
| 14 | !! The assumption in this module is that very high vertical resolution is |
|---|
| 15 | !! needed in order to properly resolve the vertical diffusion of water in |
|---|
| 16 | !! the soils. Furthermore we have taken into account the sub-grid variability |
|---|
| 17 | !! of soil properties and vegetation cover by allowing the co-existence of |
|---|
| 18 | !! different soil moisture columns in the same grid box. |
|---|
| 19 | !! This routine was originaly developed by Patricia deRosnay. |

| 3878 | !! SUBROUTINE : hydrol_soil |
|---|
| 3879 | !! |
|---|
| 3880 | !>\BRIEF This routine computes soil processes with CWRR scheme (Richards equation solved by finite differences). |
|---|
| 3881 | !! Note that the water fluxes are in kg/m2/dt_sechiba. |
|---|
| 3882 | !! |
|---|
| 3883 | !! DESCRIPTION : |
|---|
| 3884 | !! 0. Initialisation, and split 2d variables to 3d variables, per soil tile |
|---|
| 3885 | !! -- START MAIN LOOP (prognostic loop to update mc and mcl) OVER SOILTILES |
|---|
| 3886 | !! 1. FIRSTLY, WE CHANGE MC BASED ON EXTERNAL FLUXES, ALL APPLIED AT THE SOIL SURFACE |
|---|
| 3887 | !! 1.1 Reduces water2infilt and water2extract to their difference |
|---|
| 3888 | !! 1.2 To remove water2extract (including bare soilevaporation) from top layer |
|---|
| 3889 | !! 1.3 Infiltration |
|---|
| 3890 | !! 1.4 Reinfiltration of surface runoff : compute temporary surface water and extract from runoff |
|---|
| 3891 | !! 2. SECONDLY, WE UPDATE MC FROM DIFFUSION, INCLUDING DRAINAGE AND ROOTSINK |
|---|
| 3892 | !! This will act on mcl (liquid water content) only |
|---|
| 3893 | !! 2.1 K and D are recomputed after infiltration |
|---|
| 3894 | !! 2.2 Set the tridiagonal matrix coefficients for the diffusion/redistribution scheme |
|---|
| 3895 | !! 2.3 We define mcl (liquid water content) based on mc and profil_froz_hydro_ns |
|---|
| 3896 | !! 2.4 We calculate the total SM at the beginning of the routine tridiag for water conservation check |
|---|
| 3897 | !! 2.5 Defining where diffusion is solved : everywhere |
|---|
| 3898 | !! 2.6 We define the system of linear equations for mcl redistribution |
|---|
| 3899 | !! 2.7 Solves diffusion equations |
|---|
| 3900 | !! 2.8 Computes drainage = bottom boundary condition, consistent with rhs(ji,jsl=nslm) |
|---|
| 3901 | !! 2.9 For water conservation check during redistribution, we calculate the total liquid SM |
|---|
| 3902 | !! at the end of the routine tridiag, and we compare the difference with the flux... |
|---|
| 3903 | !! 3. AFTER DIFFUSION/REDISTRIBUTION |
|---|
| 3904 | !! 3.1 Updating mc, as all the following checks against saturation will compare mc to mcs |
|---|
| 3905 | !! 3.2 Correct here the possible over-saturation values (subroutine hydrol_soil_smooth_over_mcs2 acts on mc) |
|---|
| 3906 | !! Here hydrol_soil_smooth_over_mcs2 discard all excess as ru_corr_ns, oriented to either ru_ns or dr_ns |
|---|
| 3907 | !! 3.3 Negative runoff is reported to drainage |
|---|
| 3908 | !! 3.4 Optional block to force saturation below zwt_force |
|---|
| 3909 | !! 3.5 Diagnosing the effective water table depth |
|---|
| 3910 | !! 3.6 Diagnose under_mcr to adapt water stress calculation below |
|---|
| 3911 | !! 4. At the end of the prognostic calculations, we recompute important moisture variables |
|---|
| 3912 | !! 4.1 Total soil moisture content (water2infilt added below) |
|---|
| 3913 | !! 4.2 mcl is a module variable; we update it here for calculating bare soil evaporation, |
|---|
| 3914 | !! 5. Optional check of the water balance of soil column (if check_cwrr) |
|---|
| 3915 | !! 5.1 Computation of the vertical water fluxes |
|---|
| 3916 | !! 5.2 Total mc conservation |
|---|
| 3917 | !! 5.3 Total mc should not reach zero, or the tridiag solver will have problems |
|---|
| 3918 | !! 6. SM DIAGNOSTICS FOR OTHER ROUTINES, MODULES, OR NEXT STEP |
|---|
| 3919 | !! 6.1 Total soil moisture, soil moisture at litter levels, soil wetness, us, humrelv, vesgtressv |
|---|
| 3920 | !! 6.2 We need to turn off evaporation when is_under_mcr |
|---|
| 3921 | !! 6.3 Calculate the volumetric soil moisture content (mc_layh and mcl_layh) needed in thermosoil |
|---|
| 3922 | !! 6.4 The hydraulic conductivities exported here are the ones used in the diffusion/redistribution |
|---|
| 3923 | !! -- ENDING THE MAIN LOOP ON SOILTILES |
|---|
| 3924 | !! 7. Summing 3d variables into 2d variables |
|---|
| 3925 | !! 8. XIOS export of local variables, including water conservation checks |
|---|
| 3926 | !! 9. COMPUTING EVAP_BARE_LIM_NS FOR NEXT TIME STEP, WITH A LOOP ON SOILTILES |
|---|
| 3927 | !! The principle is to run a dummy integration of the water redistribution scheme |
|---|
| 3928 | !! to check if the SM profile can sustain a potential evaporation. |
|---|
| 3929 | !! If not, the dummy integration is redone from the SM profile of the end of the normal integration, |
|---|
| 3930 | !! with a boundary condition leading to a very severe water limitation: mc(1)=mcr |
|---|
| 3931 | !! 10. evap_bar_lim is the grid-cell scale beta |
|---|
| 3932 | !! 11. Exit if error was found previously in this subroutine |

|---|

| 5645 | !! Therefore, there is no more smoothing, and this helps preventing the saturation of too many layers, |
