Examples of Unsaturated soil in a sentence

  • Unsaturated soil surrounding the drainfield is extremely effective at removing disease-causing viruses, bacteria, and parasites.

  • Unsaturated soil has pores containing both air and water so aerobic microorganisms living in the soil can effectively treat the wastewater as it travels through the____________.

  • Unsaturated soil testing is costly, time consuming, and difficult to conduct.

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

  • 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 sampling followed by the appropriate laboratory analyses (reported on a dry weight basis) to determine the nature, degree and extent of contaminated soil.

  • Unsaturated soil is determined by seasonal high water table evaluations, which is underestimated because methods do not account for capillary action.

  • Unsaturated soil triaxial testing module for sample size of 50mm diameter x 100mm height– 01 no.

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

  • Infiltration means water other than wastewater that enters a sewer system (including sewer system and foundation drains) from the ground through such means as defective pipes, pipe joints, connections, or manholes. Infiltration does not include, and is distinguished from, inflow.

  • Hydraulic fracturing means the fracturing of underground rock formations, including shale and non-shale formations, by manmade fluid-driven techniques for the purpose of stimulating oil, natural gas, or other subsurface hydrocarbon production.

  • Blasting means changing the level or grade of land or rendering, tearing, demolishing, moving, or removing earth, rock, buildings, structures, or other masses or materials by seismic blasting or the detonation of dynamite or any other explosive agent.

  • Produced water means water extracted from the earth from an oil or natural gas production well, or that is separated from oil or natural gas after extraction.

  • Degradation means a decrease in the useful life of the right-of-way caused by excavation in or disturbance of the right-of-way, resulting in the need to reconstruct such right-of-way earlier than would be required if the excavation or disturbance did not occur.

  • Plant means the machinery and apparatus intended to form or forming part of the Works.
