3. A soil sample was taken with a cylindrical metal core having a volume of 300 cm3. The soil was saturated with water and then drainage water was allowed to drip. Meanwhile, evaporation of water from the soil was prevented. The drained soil sample weighed 500 g before oven drying and 350 g after oven drying. Calculate the following: a. bulk density (pb) b. moisture content by mass(%0m) and by volume (%0v) C. porosity (assume ps = 2.65 g/cm3) d. cm of water per 100 cm depth of soil

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.
