Web:For the bail-test geometry shown in Figure 8.21(a), the method involves the preparation of a_ plot of ~ecovery data in the form H-h/H-H0 versus t. The plot is prepared on semilogarithmic paper with the reverse format tQ that of' the Hvorslcv test; the H ~ h/H-H0 scale is linea,r, while the u~l~ is loprithmic. WebIn the laboratory, two common tests are generally used to determine this soil property. These two tests are the falling head permeability test and the constant head permeability test. Which test is used depends upon the type of soil to be tested. For soils of high permeability (sands and gravels) a constant head test is used.
