<p>The subject of this paper is exposed-geomembrane-lined ponds whose leakage to the environment is highly undesirable. Such ponds are actually quite common in industrialized settings, and they form an important part of the operating infrastructure of many ...

The focus of this paper is on applications (e.g. some leachate collection layers in landfills) where a drainage system consists of a geocomposite overlain by a sand layer. If the geocomposite does not have sufficient flow capacity to convey all the collected ...

The paper provides equations for the hydraulic design of liquid collection layers. A first series of equeations gives the maximum thickness of the liquid collected in a liquid collection layer. These equations are used in design to check that the maximum liquid ...

Liquid collection layers used in landfills often comprise two sections with different slopes. Typically, one of the slopes ismuch steeper than the other one. The steeper slope is generally the downstream slope in a landfill cover and the upstream slope in ...

This paper provides a method for designing anchor benches and trenches used to secure geomembranes exposed to wind action. Only the cases where anchorage is provided by gravity (i.e. by the weight of the material in the bench or trench) are considered. Anchorage ...

This technical note presents an extension of earlier analytical methods published in 1995 by Giroud et al. for evaluating the uplift of geomembranes by wind. The extension incorporates: (i) the influence on wind uplift of the slope inclination of an exposed ...
