Sentence examples for phreatic surface from inspiring English sources

Two failure modes of natural slopes are considered in this work, namely, long slope with phreatic surface parallel to the ground surface and slope with emerging phreatic surface.

The role of drainage system is also vital as it shifts the phreatic surface ensuring the safety of downstream toe.

where h is the height of phreatic surface measured above the impermeable sloping bed in the vertical direction.

This is performed by considering the Darcy equation with the permeability taking two different values and a fully saturated media below the phreatic surface.

The extensive dataset which was collected included rainfall, evapotranspiration, soil property data, channel geometry, phreatic surface elevation, soil water potential and stream discharge.

Following a prescribed method, blind predictions were made of ten features of the phreatic surface, soil water potential and surface runoff responses.

Observed craters were formed in the lava surface by phreatic eruptions.

Here, either sulfur-bearing steam altered the volcanic ash to low-permeability clays, or explosive interactions between rising magma and groundwater or surface water (phreatic eruptions) formed exceptionally fine ash that also would reduce the permeability of the lake bed.

Detection of such narrow surface deformations during phreatic eruptions demonstrates the usefulness of InSAR analysis in volcano monitoring.

where γ w is the unit weight of water (9.81 kN/m3), h is the height of phreatic line from the sliding surface obtained by groundwater simulation (Eq. 9) and θ is the slope angle.

During volcanic unrest (including phreatic eruptions), perturbations of the water surface and strong upward air currents caused by enhanced lake water evaporation can further hamper efforts to sample water near the lake surface.
