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.

1.4 A test for the relative density of soil in place was performed by digging a small hole in the soil. The volume of the hole was 400 ml and the moist weight of the excavated soil was 9 N. after oven drying, the weight was 7.8 N. Of the dried soil, 4N was poured into a vessel in a very loose state, and its volume was found to be 270 ml. The same weight of soil when vibrated and compacted had a volume of 200 ml. Determine the relative density.
Describe the void ratio changes from the initial state to the consolidated state and to the failure state and then explain the causes for the changes.
During the completion of a construction project, a soil sample was taken from an area of compacted earth fill for a sand-cone in-place density test. The following were obtained from the results of the test: • Weight of sand used to fill the test hole and the funnel of the sand-cone device = 845 g • Weight of sand to fill the funnel of the sand-cone device = 323 g • Unit weight of sand = 15.71 kN/m3 • Weight of wet soil excavated from test hole = 622 g • Moisture content of the soil excavated from the test hole = 16% %3D %3D Calculate the dry unit weight (kN/m³) of the excavated material
