soil_specific_heat {TrenchR}

Soil Specific Heat

Description

The function estimates soil specific heat (J kg^-1 K^-1) using the methods of deVries (1963). The function incorporates the volume fraction of organic material, minerals, and water in soil.

Usage

soil_specific_heat(x_o, x_m, x_w, rho_so)

Arguments

x_o

numeric volume fraction of organic material (0-1).

x_m

numeric volume fraction of minerals (0-1).

x_w

numeric volume fraction of water (0-1).

rho_so

numeric particle density of soil in (kg m^-3) (bulk density).

Value

numeric soil specific heat (J kg^-1 K^-1).
