Abstract
Covers with capillary barrier effects (CCBEs) can be used as oxygen barriers to limit gas flux into waste disposal sites. Laboratory and field measurements show that the hydraulic behaviour of such a layered cover system is influenced by its slope geometry and gravity drainage, which can result in local desaturation that may be detrimental to cover performance. Such desaturation can be minimized by placing a suction break in the moisture-retaining layer of the inclined cover. This novel approach was applied in the field to an existing inclined CCBE. The three-layer cover was then subjected to different boundary conditions to evaluate the influence of the suction break on hydraulic behaviour. Volumetric water content and suction measurements demonstrated that a zone of water saturation and low suction was created upslope of the suction break under natural climatic conditions. The hydrological behaviour close to the suction break was not significantly affected by a forced drought of 78 days (without water infiltration). The results also reveal that the suction break had a relatively limited upslope zone of influence (typically less than 10 m). The monitoring results are confirmed by geophysical measurements used to characterize water distribution in the inclined CCBE.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
