...M. Ghasemi; V. Di Battista The contaminant transport of chloride through a single composite liner facility comprised of a geomembrane ( GMB ) with holed wrinkles over a compacted clay liner ( CCL ) and an aquitard underlain by an aquifer is examined. A two-dimensional finite element (2D FE ) model...

... designed for this purpose. The tests performed were aimed at verifying the influence of the structural and material properties of the GCL on the transmissivity along the GM–GCL interface and flow rates through composite liners. Four types of GCLs with two different bonding processes (stitch-bonded...

...N. Touze-Foltz; J. P. Giroud This technical note presents empirical equations for the evaluation of the rate of advective flow through composite liners, i.e. liners comprising a geomembrane and a low-permeability soil layer. The advective flow considered is due to large circular defects...

...J. P. Giroud; N. Touze-Foltz This paper presents equations for calculating the rate of liquid flow through defects in the geomembrane component of a composite liner. The considered defects have a uniform width and have a length that is finite or infinite. Two types of defects are considered: narrow...

...N. Touze-Foltz; J. P. Giroud This paper presents empirical equations for the evaluation of advective flow rates through composite liners (i.e. liners comprising a geomembrane and a low-permeability soil layer). The advective flow is due to defects in the geomembrane and depends on contact...

... transmissivity of the secondary leachate collection layer. Also, the loss of bentonite particles from the GCL may decrease the performance of the composite liner. The present paper provides theoretical analyses of these detrimental effects of bentonite particle loss, which lead to an acceptance criterion...

...J.P. Giroud; K. Badu-Tweneboah; K.L. Soderman The purpose of this paper is to provide an approach for comparing the effectiveness of geosynthetic clay liners (GCLs) and compacted clay liners (CCLs) used in association with geomembranes to form composite liners. Comparing the effectiveness...

...J.P. Giroud; K.L. Soderman; K. Badu-Tweneboah A number of landfills are designed with a double liner system that includes a geomembrane liner and a composite liner. The design engineer must select which of these two liners should be the primary liner. A comparative study is presented in this paper...

...J.P. Giroud Equations available to date for calculating the rate of liquid migration through a composite liner due to geomembrane defects require the use of graphs to obtain the value of one of the terms of the equations for the case where the liquid head is larger than the thickness of the low...

...T. Tao; J. Yan; X. Tao; F. Fu; H. Zhou The rock-fill dam at the Xiaolingtou Reservoir is 36.4 m high and uses a geotextile/geomembrane composite liner to prevent seepage. The composite consists of geotextiles bonded to both sides of a geomembrane. The seepage prevention properties of the composite...
