Sentence examples for permeable horizontal from inspiring English sources

Considering that the wells are shallow (mostly 5 10 m depth) and that in the research area, the soil is easily permeable, horizontal hydraulic conductivity values are high and a rapid transfer of nitrate from pollution sources to the well is expected, contributing to variability in individual wells.

In this study we considered an alternative method involving the use of solid potassium permanganate to create a horizontal permeable reactive barrier for oxidizing VOC vapors.

The results suggest that field application of a horizontal permeable reactive barrier can be a viable technology against upward migration of VOC vapors through the unsaturated zone.

In this work we introduce a 1-D analytical solution that can be used for the design of horizontal permeable reactive barriers (HPRBs) as a vapor mitigation system at sites contaminated by chlorinated solvents.

We identified two highly permeable sections where the horizontal hydraulic conductivity is 3.7 6.4 times of the equivalent hydraulic conductivity obtained from the pumping test.

This fluid will react with the calcium carbonate in the filter cake and the calcium carbonate in the formation to produce high viscosity fluid that will divert the fresh flow through the less permeable sections in the horizontal well.

Based on the diversion mechanism obtained from the experimental work, Na3HEDTA will react with the carbonates in the sandstone formation and this reaction will produce high viscosity that will divert the flow of the fluid through the less permeable part in the horizontal sections.

This phenomenon, in conjunction with a highly permeable aquifer formation and small horizontal hydraulic gradients, makes modeling analysis and model calibration a formidable challenge.

Initially, simulations of hot water displacement were performed in all these permeable media with a multilateral horizontal well injector and a vertical producer.

Physical remediation techniques include soil washing, vitrification, encapsulation of contaminated areas by impermeable vertical and horizontal layers, electrokinesis, and permeable barrier systems.

The second most difficult question (i.e., question 1.5 on the Wright map) was one of the innovative assessment context, in which we replace the classical U-tube example with a horizontal tube divided by a selectively permeable membrane that is only permeable to water.
