Název v původním jazyce

Anisotropy of unsaturated hydraulic properties of compacted mineral capping systems seven years after construction

Popis výsledku v původním jazyce

The mechanical compaction of soil material of mineral landfill systems affects the continuity and connectivity of the complex soil pore network. A horizontally-oriented layering is intended to generate a slope-induced lateral water flow out of mineral capping systems that is sufficient to minimise the statutory required vertical percolation through the underlying waste body and the potential leachate. In this case, soil compaction affects both the porosity and water retention as capacity values and the hydraulic conductivity as intensity parameter. The idea of this study was to combine information on both soil properties in an extended anisotropy factor based on the soil water diffusivity. The analysis is focused on the direction-dependent soil hydraulic properties of a mechanically compacted landfill capping system.
