Simulation of the soil-water characteristic curve using laboratory tests and empirical models for Cubans unsaturated soils

The task of characterizing an unsaturated soil is a very hard one, unlike the classics hypothesis like 100% of saturation are not considerable now. This work focuses on obtaining and simulating the soil-water characteristic curve for unsaturated soils from: Sagua la Grande, Formation Capdevila, Cien...
