Influence of Soil Hydraulic Characteristics in Modelling Capillary Barrier Systems
The use of a capillary barrier system (CBS) to control the water infiltration into the native slopes is widely studied at present as a counter-measure against rainfall-induced landslides. The CBS consists of finer-graded material over the coarser graded material to suspend water at the interface. Experimental determination of suitable material combinations for a given rainfall region is tedious and time-consuming. Theoretical evaluation of CBS is thus receiving significant interest. The determination of breakthrough head and pore pressure variations in the CBS slopes requires considerable study. In the present study, a model based on Richard’s flow equation and proposed interface boundary conditions was presented to study the influence of the CBS effect for a given material combination. The influence of different hydraulic conductivity models (HCF) on the breakthrough head was studied. The proposed model is helpful to find the optimal combination of layered systems to design efficient CBS.
