Soil simulations
Setting soil hydraulic properties
When selecting WATERTRANSPORTMODEL_SOIL = RICHARDSEQUATION
, the grain size of the soil layers in the *.sno file is used to determine the water retention properties of the soil, according to the following values:
type | rg |
---|---|
ORGANIC | 0.2 |
CLAY | 0.5 |
CLAYLOAM | 1.5 |
LOAM | 2.5 |
LOAMYSAND | 3.5 |
SAND | 4.5 |
SANDYCLAY | 5.5 |
SANDYCLAYLOAM | 6.5 |
SANDYLOAM | 7.5 |
SILT | 8.5 |
SILTYCLAY | 9.5 |
SILTYCLAYLOAM | 10.5 |
SILTLOAM | 11.5 |
WFJGRAVELSAND | 12.5 |
The soil types refer to the ROSETTA Class Average Hydraulic Parameters. More experimental parameters have been published since, for example here.
Note 1: when using Richards equation, theta[SOIL] is set according to the soil type and the values specified in the *.sno file will be ignored.
Note 2: WFJGRAVELSAND is a special type created for initial simulations for Weissfluhjoch. In later simulations, LOAMYSAND has been used for Weissfluhjoch.
