CENTRIFUGE MODELLING OF SALT WATER INTRUSION IN CLAY LINERS

The phenomenon of intrusion of salt water in to the fresh water supply is a common occurrence in most of the coastal areas. This process is largely influenced by the various physico-chemical-mineralogical properties of the soil. As such, the design of a containment system in the form of a natural clay liner calls for a proper understanding of the process. Centrifuge Modelling can be used as an effective tool in modelling such a phenomenon.
In this report, an effort has been made to model the intrusion of salt water in Marine Clay and Black Cotton soil using the Geotechnical Centrifuge available in the Soil Engineering Laboratory, Indian Institute of Technology, Powai, Bombay. Modelling of models has been achieved, which ensures the usefulness of centrifuge modelling in studying such mechanisms.
