2D-Flow analysis through zoned earth dam using finite element approach Hayder Hassan Al. Jairry.

Abstract EN

This paper presents an application of finite element analysis using CivilFEM / ANSYS (11) software to predict two dimensional steady state water seepage through an earth dam of two soil zones resting on impervious base.

Seepage characteristics (quantity and length of seepage surface) produced at downstream are investigated against permeability coefficient ratio changing of the two soil zones, and based on results of the solution it was found that seepage quaantity and velocity downstream are very sensitive to any change of permeability ratio of the two soil zones forming the dam.
