Initializing soil layers when using Richards equation

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

Here, the soil types refer to the ROSETTA Class Average Hydraulic Parameters.

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.
