Workshop: Geosynthetics for drainage and filtration in landfill barrier systems

SESSION D13 / 14 October 2021 / 15:00 - 16:30 + discussion panel 17:00 - 18:00
Workshop: Geosynthetics for drainage and filtration in landfill barrier systems (organized by the IGS TC-H)
Chair / Presidente: Daniele Cazzuffi (IT)

This workshop is organized by the Technical Committee on Hydraulics of the International Geosynthetics Society.
The workshop will present the state-of-the-art for the application of drainage geosynthetics in landfill barrier systems. The development of their use for drainage and filtration functions will be illustrated, including the drainage of rainwater on capping applications, biogas management, use of drainage geosynthetics in leachate collection layers and as part of double lining systems. Recent developments will be presented: new products with enhanced friction resistance, structures with enhanced resistance to creep or geotextile intrusion. Aspects related to the development of international standards and guidelines will be outlined, as well as the contribution of geosynthetics to sustainable development in civil engineering. Following a series of introductory lectures, the authors will entertain a discussion on the topic and receive questions from the audience.

Part 1: Introductory lectures (15:00 - 16:30):

  • E. Blond (CA)
    Designing geocomposites drains in leachate collection layers and double lining systems

  • P. Rimoldi (IT)
    Designing geocomposites drains for hydraulic capacity: current codes and standards

  • P. Recalcati (IT)
    Designing geocomposites drains for veneer stability

  • M.C. Mandaglio, S. Bilardi, N. Moraci (IT)
    Relevance of soil geotextile filter long term behaviour on the design of environmental and civil works

  • C. Tarnowski (DE)
    Use of geocomposite drains for leachate recirculation in bioreactors

Part 2: Discussion panel (17:00 - 18:00):

The topics presented in the first part of the workshop will be discussed, considering: recent change in regulations, practice in other parts of the world, and any question arising from the audience.
