ABSTRACT
The paper presents a review and classification of methods of the determination of the permeability coefficient and research instruments, well-known from literature. Special emphasis has been put on the discussion of experimental methods, as the most exact values of this parameter are obtained on their basis. Apart from this, attention has been paid to modern measuring instruments which serve to define the consolidation and permeability coefficients in coherent soils. The introduction of suggested changes in the current methodology of studies into practice makes values of the discussed parameters obtained in situ and from laboratory tests comparable.
Key words: seepage, consolidation, permeability coefficient, hydraulic gradient, field tests, laboratory tests, investigative methods, measuring apparatus, cohesive soils.
