| 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_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. |
|---|
| 20 | !! |
|---|
| 21 | !! RECENT CHANGE(S) : November 2020: It is possible to define soil hydraulic parameters from maps, |
|---|
| 22 | !! as needed for the SP-MIP project (Tafasca Salma and Ducharne Agnes). |
|---|
| 23 | !! Here, it leads to change dimensions and indices. |
|---|
| 24 | !! We can also impose kfact_root=1 in all soil layers to cancel the effect of |
|---|
| 25 | !! roots on ks profile (keyword KFACT_ROOT_CONST). |
|---|
| 26 | !! July 2022: New irrigation scheme. Here new irrigation demand based in |
|---|
| 27 | !! soil moisture deficit, and irrigation application. |
