3.2.10. SUEWS_Soil.txt#

SUEWS_Soil.txt specifies the characteristics of the sub-surface soil below each of the non-water surface types (Paved, Bldgs, EveTr, DecTr, Grass, BSoil). The model does not have a soil store below the water surfaces. Note that these sub-surface soil stores are different to the bare soil/unmamnaged surface cover type. Each of the non-water surface types need to link to soil characteristics specified here. If the soil characteristics are assumed to be the same for all surface types, use a single code value to link the characteristics here with the SoilTypeCode columns in SUEWS_NonVeg.txt and SUEWS_Veg.txt.

Soil moisture can either be provided using observational data in the met forcing file (the xsmd column when SMDMethod = 1 or 2 in RunControl.nml) and providing some soil properties here, or modelled by SUEWS (SMDMethod = 0 in RunControl.nml).

No.
