Abstract:
In the hydro geological study, hydraulic conductivity is one of the most important parameters, but also a difficult parameter to determine. In the present study, hydraulic conductivity in soils was determined by field method and by using 5 empirical formulae Brayer, Kozeny-Carman, Slitzer, Terzaghi and Hazen focusing on the different regions of Medak district, Telangana state and evaluated the empirical methods with field method. Samples had been taken from different locations namely Sangareddy, Siddipet, Narsapur, Zahirabad and Sadasivpet. These samples were tested to calculate hydraulic conductivity by empirical formulae and compared to each other. Results showed that the five empirical formulae estimated hydraulic conductivities of the various soil samples well within the known ranges. Hazen formula proved to be the best estimator of most samples analyzed and may be, even for a wide range of other soil types. However, some of the formulae underestimated or overestimated hydraulic conductivity; even of the same soils. Hydraulic conductivity of the Medak district soils can be estimated by the Hazan formula instead of using field method.
