Geotextile containment for hydraulic and environmental engineering

Abstract

Historically, geotextile containment has been used to encapsulate sandy soils to permit their use as flexible, erosion-resistant, mass-gravity structures in hydraulic and marine applications. More recently, geotextile containment has been used as a means of disposing of, and dewatering, various waste streams and contaminated sediments. The paper reviews the three main geotextile containment units in use – geotextile tubes, geotextile containers and geotextile bags – and analyses their use in a wide range of hydraulic and environmental applications. Special attention is given to the use of geotextile containment for the isolation, dewatering, and disposal of specific waste streams and contaminated sediments.
