Setting soil hydraulic properties
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:
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.
