CALCULATION OF SOIL WATER DIFFUSIVITY USING A MODEL FOR SOIL MOISTURE PROFILE UNDER DIFFERENT SALINITY CONDITIONS
A closed formed model modified from that of van Genuchten (1980) was used to fit the data of soil moisture profile ( θ vs. λ ) from which the slope dλ/dθ can be evaluated and then the soil water diffusivity [D(θ)] can be calculated. Diffusivity was calculated for three soil textures under different...
