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 ...

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 ...
