Moisture and heat flow in unsaturated soil

Many countries in the tropical and sub-tropical regions experience mainly two seasons: dry and wet. In general, this climatic condition is not conducive to the weathering of rock formation into residual soils. The shear strength of these residual soils is high when unsaturated. However, numerous slo...
