Many geotechnical and geoenvironmental problems, involving unsaturated soils, require an understanding of the hydraulic relations between degree of saturation and matric suction head. For example, in modeling the flow of contaminants in unsaturated soils and coupled flow and stress-strain behavior of unsaturated soils, information about hydraulic relations is essential. In this paper, the results of the relationship between degree of saturation and matric suction head are presented under static equilibrium and during dynamic flow of water using Buchner funnel and fully instrumented 2-D tank. Several scanning loops were simulated by varying the water level between predetermined levels to achieve the objectives of each test. The major influences of the dynamic flow on hydraulic relations are highlighted and discussed.
