4.2.10. 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 (SMDMethod
= 1 or 2 in
RunControl.nml) and providing some metadata information here (OBS columns),
or modelled by SUEWS (SMDMethod
= 0 in RunControl.nml).
Caution
The option to use observational data is not operational in the current release!
