Examples of Unsaturated soil in a sentence

  • Unsaturated soil mechanics is relatively a new discipline developed around in the past 40 years.

  • Unsaturated soil moisture redistribution and capillary rise effects are calculated using the van Genuchten–Mualem equations and soil hydraulic properties (Wösten and van Genuchten, 1988).

  • Unsaturated soil in this zone is categorized according to the degree of saturation as shown in Figure 2.3. Above the water table, pore water pressure will be negative with respect to atmospheric pressure, but immediately above the water table, a new zone, defined as capillary fringe, where degree of saturation is approximately 100 percentages.

  • Unsaturated soil, fill materials, and building debris at the site appeared to be un-impacted by site-related contaminants.

  • Unsaturated soil samples collected to date from the overburden in the Northern Area do not indicate a source of soil contamination that contributes to the contaminated groundwater plume in the Northern Area.

  • Landfill Drinking water receptor well Unsaturated soil layer Ground water flow Figure 7.

  • Unsaturated soil is normally considered as a three-phase system, i.e., solid, gas (air), and fluid (water).

  • Unsaturated soil regions have significant changes of pore water pressure distribution from the rainfall infiltration.

  • Unsaturated soil quality was noted to be impacted by PCBs, volatile organic compounds (VOCs), naphthalene, semi-volatile organic compounds (SVOCs) and metals (arsenic, barium, cadmium, copper, lead, mercury, and nickel) above the NYSDEC restricted Commercial Use Soil Cleanup Objectives.

  • Unsaturated soil mechanics is increasingly attracting scientific attention, playing an important role in the prediction of contaminant transport in porous soil media.
