Experimental study to evaluate soil water retention curve of HYPER clay geosynthetic clay liner

Abstract Geosynthetic clay liners are widely used as hydraulic barrier due to their low conductivity but bentonite in the loses its effectiveness significant thermal fluxes by both diurnal and seasonal heating cooling cycles. Modified sodium carboxy methyl cellulose-based (HYPER clay) has shown better performance situations. A possible reason for this improved of HYPER based geosynthetic liner is improvement suction under changing conditions. Thus, relationship between soil moisture content, also called water retention curve, needs be estimated. Therefore, we investigated soil-water curve compared it with untreated liner. The article presents test results on wetting path conducted prototypes containing assessed contact filter paper method relative humidity sensor. showed that a high volumetric content thus, at given value. In other words, can considered potential alternative conventional capacity.
