Simulation of barrier heterogeneity and preferential flow effects on the performance of shallow land burial facilities
Compacted soil barriers constructed at landfill sites have some degree of heterogeneity in hydraulic properties that may lead to a decline in barrier integrity and performance. A computer modeling study of the water dynamics of compacted soil barriers for a mesic site in eastem Tennessee was undertaken to identify possible situations that could lead to barrier failure. A water dynamics model for soil-plant systems (UTM) was applied to three landfill construction scenarios, and varying degrees of heterogeneity of hydraulic properties for the cap and liner were introduced with a scaling procedure. Simulations were conducted for three annual contrasting rainfall conditions, and sensitivity analysis and Monte Carlo methods were used in the investigation.
