Field applications of hydraulic conductivity

Hydraulic conductivity is one of the hydraulic properties of soil defined as a measurement of the ability of a porous medium to permit water movement or fluid flow through it. It is denoted by the letter K. It is influenced by the density and viscosity of the fluid. It is also called permeability. Hydraulic conductivity is defined as the ratio of velocity to the hydraulic gradient. The different methods used to determine the hydraulic conductivity are laboratory methods (constant head permeability tests and falling head tests), in-situ field methods (pumping in and pumping out tests), small scale field tests (infiltration tests and slug tests), and indirect methods such as estimation from grain size, consolidation test data, and horizontal capillary test. The pedotransfer function (PTF) method is a specific empirical estimating approach employed in the soil sciences is also used to determine the hydraulic conductivity of the soil.

An embankment for a highway 30 m wide and 1.5 m in compacted thickness is to be constructed from sandy soil trucked from a borrow pit. The water content of the sandy soil in a borrow pit is 15% and its void ratio is 0.69. The swell index is 1.2.

An embankment for a highway 30 m wide and 1.5 m in compacted thickness is to be constructed from sandy soil trucked from a borrow pit. The water content of the sandy soil in a borrow pit is 15% and its void ratio is 0.69. The swell index is 1.2. The specification requires the embankment to be compacted to a dry unit weight of 18kN/m^3. Determine, for a 1-km length of embankment, the ff; (g) The weight of water per truckload of sandy soil. (h) The degree of saturation of the sandy soil in situ. The dry density of sand with a porosity of 0.387 is 1600 kg/m3. Find the following; (i) The void ratio of the soil. (j) The specific gravity of the soil solids.
Given the ff: w=67% Gs=2.67 Gwet=19.89kN/m3. What is the degree of saturation?
A soil profile consists of 3m of clean sand (γ=18kN/m³) over 10m of silt (γ=17kN/m³, kv=1 x 10-8m/s) over 12m of clay (γ=17kN/m³, kv=4 x 10-9m/s) over gravel. Piezometers installed at middepth of the sult later and at the top of the gravel layer measure, respectively, piezometric heads of 4m and 3m. Assuming one-dimensional flow in the vertical direction, compute the flow rate in m³/year/10,000m². Also, compute at 16m below the ground surface the total veritcal stress, effective stress, and porewater pressure.
