Abstract
The study of seepage through porous media is of great importance in many fields of engineering such as, seepage through earth dams, seepage under heading-up structures, and seepage from waterways. There are two main of seepage, confined and unconfined flow seepage. The objectives of this study are to study the characteristics of seepage through homogeneous isotropic earth dams rested on an impervious base and provided with different drainage systems. The considered drainage systems are chimney, toe and horizontal filters. Seepage through earth dams provided with chimney, toe, and horizontal filters are studied numerically using boundary element method (B.E.M) and experimentally using sand model. The relative effects of the using three different filters and their positions are studied. Seepage discharge, height of exit point, and phreatic surface location are determined and compared.
