| 27 | !! ** Purpose : computes pore water dissolution and reaction |
|---|
| 28 | !! |
|---|
| 29 | !! ** Methode : implicit simultaneous computation of undersaturation |
|---|
| 30 | !! resulting from diffusive pore water transport and chemical |
|---|
| 31 | !! pore water reactions. Solid material is consumed according |
|---|
| 32 | !! to redissolution and remineralisation |
|---|
| 33 | !! |
|---|
| 34 | !! ** Remarks : |
|---|
| 35 | !! - undersaturation : deviation from saturation concentration |
|---|
| 36 | !! - reaction rate : sink of undersaturation from dissolution |
|---|
| 37 | !! of solid material |
