Advances in approaches for determining unsaturated soil hydraulic properties

  • This paper introduces the advances and status in research of various direct methods(include two categories,i e, laboratory and field methods) and indirect methods such as the Pedo transfer function,the Fractal,the Morphology,the Numerical inverse method and the empirical formula etc.for determining soil hydraulic properties,including their inherent advantages and deficiencies.In order to extend the application and enhance the prediction accuracy,new experimental techniques need to be cont inuously introduced and measurement instruments improved.Concurrent ly,the comprehensive studies integrating all theoretical and experimental information relevant to the prediction of unsaturated soil hydraulic properties should be carried out.
