Large scale physical model tests on the stability of geotextile tubes

To test the stability of sand filled geotextile tubes under wave attack, tests were performed in the Delta Flume of Deltares on a scale of approximately 1:2 - 1 :4. Wave conditions in the model varied up to 1.5 m significant wave height. Seven test series with different geometric conditions were tested. In four test series, single placed tubes...

Dewatering sewage sludge with geotextile tubes

Municipal sewage was placed in geotextile bags for the purpose of evaluating the dewatering and consolidation capabilities of large geotextile tubes and effluent water quality. A proposed AS TM test method for determining the flow rate of suspended solids from a geotextile containment system for dredged material was used to conduct tests to...

Design aspects of geotubes and geocontainers: What we know and what we don't know

Geotubes and geocontainers (Nicolon patent) hydraulicaliy and/or meclianically filled with (dredged) materials have been successfully applied in coastal engineering in recent years. They can also be used to store and isolate contaminated materials from harbour dredging. Some informations on these systems are given in this document.

Geosynthetic confined pressurized slurry (GeoCoPS)

Computer program to calculate water pressure inside a geotube or similar structure made from geotextiles

Field trip to Barren Island, Chesapeake Bay, Maryland for Geotube application

Site visit and design background of geotubes applied on Barren island, pressure calculations inside tube

Longard tube applications manual

Site inspections of application of Longard tubes in Europe at various locations. The intend of this report is to provide possible applications of the system in coastal and hydraulic applications.
