Sentence examples for pervious layer from inspiring English sources

The sensitivity analysis was performed for two different sedimentological architectures, first for horizontal layers and then for a gently dipping low pervious layer above the groundwater table.

The results show that a permeability contrast of at least 100 between the most pervious layer in the weathering front and bedrock and a diffusivity of chemical species lower than 2.5 × 10−8 m2/s are required to allow instability.

In the case of calcium granules, the alternating electron dense and pervious layers have been interpreted as reflecting the intercalation of organic and mineral layers, respectively [reviewed in ref. 29], a formation that may also require prolonged time of incubation or storage.

Like the many calcium granules found in nature [51], the alternating electron dense and pervious layers found here can also be interpreted as representing intercalated layers of mineral and organic matrices, or alternatively, they may represent distinct stages of nucleation and growth.

A laminated and variegated granular morphology, displaying alternating electron-dense and pervious layers resembling "bull's eyes," could be more clearly seen with NB "strains" that had been maintained through multiple serial passages in the presence of excess serum (5 10% FBS), as illustrated by thin section images of "nanons" shown in the bottom row of Figure 5 (Q T).
