getsoiltexture_usda()

def seims.preprocess.sp_soil.SoilUtilClass.getsoiltexture_usda (   clay,   silt,   sand  )

static

The soil texture code system is from WetSpa Extension and SWAT model which is
based on the soil texture triangle developed by USDA.
The unit is percentage, silt + sand + clay [+ Rock] = 100.
    The corresponding default soil parameters (e.g. Ks, porosity) are stored in
`seims/database/SoilLookup.csv`.
Args:
    clay: clay content percentage
    silt: silt content percentage
    sand: sand content percentage

Returns:
    [Soil texture ID, Hydrological soil group, USLE K factor]

initial_soil_moisture()

def seims.preprocess.sp_soil.SoilUtilClass.initial_soil_moisture (   acc_file,   slope_file,   out_file  )

static

Initialize soil moisture fraction of field capacity, based on TWI

lookup_soil_parameters()

def seims.preprocess.sp_soil.SoilUtilClass.lookup_soil_parameters (   soil_lookup_file )

static

Reclassify soil parameters by lookup table.

Returns:
    recls_dict: dict, e.g., {'OM': '201:1.3|1.2|0.6,202:1.4|1.1|0.8'}

parameters_extraction()

def seims.preprocess.sp_soil.SoilUtilClass.parameters_extraction (   cfg )

static

Soil spatial parameters extraction.
