Figure 4: Rate of seepage analysis results For the maximum flux across the centre of the dam, the minimum and maximum values of rate of seepage of 8.64E-05 and 1.27E-04 m?/sec were observed respectively at TP2 and TP1 for the numerical method using SEEP/W. As for the analytical method, minimum and maximum values of rate of seepage of 1.49E-05 and 1.73E-04 m*/sec were observed respectively at TP2 and TP3. The values of the maximum hydraulic velocity and maximum flux results are indications of need for sufficient and well monitored compaction and careful selection of core material with a very low permeability for adequate design against piping failure. Such core materials are mostly inactive clay soils.
