Analytical solution of seepage through earth dam with an internal core

Abstract

Based on the experimental work previously presented for earth dam with internal core and done by Rezk [4], it is suggested to develop an analytical solution for the same problem and comparisons between two solutions are presented. Effect of relative permeability of core (kc/kd) on each relative seepage discharge (Q1/Q) and relative drop of phreatic surface (d/h1) due to core is investigated. Phreatic surface is drawn according to both experimental work and the analytical solution given by the authors.
