GDSCTS System: University of Zagreb

The aim of this research was to prove that the soil materials from the so called flysch deposits (which are locally available on the Istrian peninsula at low cost), can be used as the components of the liner layers in municipal landfills.

The Solution

To obtain the coefficient of permeability the constant rate of flow method was used within the GDSLAB standard hydrocon module.

The original reason for purchasing the GDSCTS system was to study the creeping behaviour of clays as part of a scientific project which was supported by the Croatian Ministry of Science. However, up until January 2009, the Rowe and Barden Consolidation cell was almost exclusively used for educational purposes, until this new research project was introduced by professor Davorin Kovacic.

Due to limited resources it took the faculty of Geotechnical Engineering at the University of Zagreb 4 years to complete their full consolidation system. Purchased in stages, it was ready for use in 2008. Two advanced pressure/volume controllers, a data logger, pore pressure and displacement transducers a copy of GDSLAB software with the standard hydrocon module, alongside full on-site training were purchased from GDS during this 4 year period, to complement the Universities existing Rowe & Barden consolidation cell. To read the rest of the case study, please download the PDF file below.
