VARIABILITY OF THE PERMEABILITY COEFFICIENT DEPENDING ON HYDRAULIC GRADIENT EXEMPLIFIED BY GLACIAL TILLS FROM RÓŻANKA
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2011, Vol 446, Issue 446
Abstract
The paper focuses on the problems of determining the permeability coefficient, one of the important criteria for selecting the ground as a sealing material. The research program included three series of measurements of the permeability coefficient on samples from North-Polish complex till, using different conditions of stress and hydraulic gradient. The results show a considerable variability of the coefficient depending on the studied conditions, which indicates the need for research to clarify the existing guidelines for permeability studies.
