GSI Webinars, Geosynthetics in Agriculture and Aquaculture

Garrison Dam National Fish Hatchery, Aquaculture Liner
In 2009, the Garrisson Dam National Fish Hatchery (North Dakota) lined an additional 8 ponds (~720,000 sq. ft.) with geomembrane. Prior to the liners, ponds lost up to 250,000 gallons of water per day do to leakage through aging soils and damage from native planktivorous species.

By Dr. Robert M. Koerner, P.E. – On Wednesday, December 11, from 11:30 am – 1:00 pm (Eastern), the Geosynthetic Institute (GSI) will continue its monthly webinar series. The forthcoming topic is “Geosynthetics in Agriculture and Aquaculture.”
REGISTER ONLINE
This webinar illustrates the many and varied applications of geosynthetics which can be (and have been) used in agriculture and aquaculture.  The users are either focused on improved productivity or lower cost of operations.
A brief explanation of geosynthetics will begin the webinar followed by specific operations.  In the agriculture area, these are various farming applications, confined animal feedlots, anaerobic digesters and emerging concepts.   In the aquaculture area, these are lined ponds, factory controlled systems and offshore fish pens and cages.
Exposed geomembrane lifetimes will be offered from the perspective of laboratory predictions as well as a benefit/cost method for geomembrane solution.  Conclusions in both areas will also be offered.

OBJECTIVES

Anaerobic digestion and biogas
The EPA AgSTAR Program has provided significant technical support and funding for the establishment of anaerobic digesters and utilization of biogas on farms in the United States.

Webinar participants will gain an overview of geosynthetics vis-à-vis various containment concepts.  In the agriculture sector, specific issues of animal waste concerns (e.g., CAFOs) will be described as well as anaerobic digesters.  In the aquaculture section, focus is on fish farming both on land and in water, including lakes and oceans.
Emerging concepts in agriculture such as enhancement of farming practices, geotextile capillary barriers, odor control floating covers, and odor permeable geomembranes will be presented.  In aquaculture the use of geogrid enclosures will be emphasized.  Exposed geomembrane lifetimes, via laboratory simulation methods, will be presented as will the benefit/cost methodology for selecting the optimum type of geomembrane.

BENEFITS

  • Learn about geosynthetics and their functions
  • Learn select aspects of farming and animal waste containment
  • Learn specific aspects about CAFO’s, anaerobic digesters, and emerging concepts insofar as geosynthetic applications are concerned
  • Learn about the three categories of fish farming insofar as fish growth and harvesting.
  • Learn about exposed geomembrane lifetime predictions based on current technology
  • Learn how to select geomembranes based on a benefit/cost ratio analysis

WHO SHOULD ATTEND
Agricultural engineers and developers dealing with all aspects of farming; aquaculture specialists in the various categories of implementation; geosynthetic manufacturers and representatives; design consultants and the testing organizations that serve them; academic and research groups; government agencies dealing with the agriculture and aquaculture industries; others desiring technical related information insofar as these geosynthetic applications are concerned.
