Hydraulic Conductivity: Comparison Between Field Testing and Indirect Techniques
Pumping and -field-permeability tests were conducted at four sites to determine soil permeability that is used in designing groundwater control systems. Laboratory tests, on soil samples extracted during site investigation, were performed. Test results were used to check the applicability of the indirect techniques relating permeability to grading characteristics. Confined, unconfined and mixed-aquifer conditions were characterized based on field measurements. It was found that it is more realistic to estimate permeability using field testing. If only data of indirect methods are available, its use sholud be limitted to tender or prelimenary studies. In this case, while implementing some justifications, Hazen's formula can give a good estimate.
