The Soils Database provides a collection of basic soils and artificial materials used to construct soil profiles. You do not access items from this table in your simulations directly, but you refer to them through the definition of soil profiles.
Defines if the soil material is a Natural soil or an Artificial material. The main difference between the two is that natural soils allow the exchange of water inside the soil layers and - if used at the surface- allow natural transpiration. The thermal properties are calculated dynamically based on the actual water content of the soil. In addition, Water Body is supported as a special material to include still water bodies of substantial depth. Note: If “Water Body” is chosen, all other parameters are not required as the physical properties of water are fixed in ENVI-met.
The volumetric water content defines the amount of liquid water per cube meter soil. For the ENVI-met simulations, three different critical threshold points need to be defined for a given soil:
These values are a constant property of the soil and its texture matrix and are normally available for a limited list of soils.
