Numerical parametric simulations for seepage flow behaviour through an earthfill dam

A finite element method is practical and applicable for many fields including for geotechnical engineering structures. Seepage through earth dam is difficult to analyse especially dams with multiple zones. Therefore, finite element is the best tool for analyzing seepage flow in an earthfill dam. The...
