WebHowever, this can be increased or decreased as needed. The gradient calculation methods and the calculation of unsaturated hydraulic conductivity were included as subroutines and can be replaced or modified as desired by the user. A computer program was written to determine hydraulic head gradients and flow vectors within a two-dimensional system. WebThe hydraulic conductivity was measured under average effective confining pressures of approximately 35, 75, 125, 175, and 250 kPa. Figure 8.10 shows the coefficient of permeability of MSW specimens stabilized with different contents of fly ash–quicklime. These results show that by increasing the content of fly ash–quicklime in the MSW …
