Sentence examples for deep confined from inspiring English sources

These allow differentiation of contaminated superficial aquifers from deep confined aquifers with baseline water quality.

The stable isotopes of water were used to improve the determination of the groundwater budget of the deep Saharan "Continental Intercalaire" (CI), a deep confined aquifer.

This finding is in accordance with other hydrogeological evidence that this aquifer, located only 4 5 m below the seafloor, is connected to fairly deep confined sandy aquifers on land of Pleistocene or Miocene age.

In this study, numerical simulations of a field multi-well pumping-recharge test in a deep confined aquifer are conducted to analyze the responses of groundwater and strata to pumping and recharge.

Our results show that shallow phreatic and deep confined groundwater differ greatly in their compositions, with a distinct spatial heterogeneity of phreatic groundwater TDS (from 365 mg/L to 5833 mg/L), which increase along the shallow groundwater flow paths.

Deformation consists in a large oblique "sagging" along a deep confined sliding surface, associated with gravitational reactivation of pre-existing (late-Alpine and recent) tectonic brittle structures, leading to the formation of N S and WNW ESE trending gravitational morpho-structures.

The installation operates without any chemical pretreatment and therefore, the concentrate can be injected into a deeper confined aquifer that contains water of similar concentration.

Alternatively, faults may act as pathways with increased vertical permeability, allowing fluids from deeper confined aquifers to migrate to and enhance liquefaction of the upper soil, as proposed previously by Wang (2007).

The water requirements of the Oued Righ region are provided by groundwater resources contained in the two aquifers: the complex terminal and the deeper confined continental intercalaire aquifer.

In aquifer systems more prone to nitrate contamination, surficial aquifers are more likely to be contaminated and at a greater extent compared to deeper, confined or unconfined aquifers.

According to these information, in addition to screen and lifting pump position in well sections, the aquifer system within the area is subdivided into three aquifers: first aquifer (shallow), principal aquifer (semi-confined), and deep aquifer (confined) (Fig. 6).
