The seaming of geosynthetics seminar to be held by the geosynthetic research institute of drexel university 14–15 December 1989
Geotextiles and Geomembranes 8 (1989) 341-342
Announcements THE SEAMING OF GEOSYNTHETICS SEMINAR TO BE HELD BY THE GEOSYNTHETIC RESEARCH INSTITUTE OF DREXEL UNIVERSITY 14-15 DECEMBER 1989 'The whole is only as good as its weakest element.' When continuity of geosynthetic materials is under consideration the above statement must be directed toward s e a m s . Due to the large planar extent of geosynthetics, seams are invariably the weakest element in almost all geosynthetic materials. Certainly, geomembrane seams are at the heart of solid waste and liquid containment systems. Their type, construction and inspection form a major part of this Seminar. All types of geomembrane seaming methods and inspection techniques need to be described and discussed so that proper methods are used in these important facilities. The available information should be collected and arranged in a single volume so that proper comparisons, along with advantages and disadvantages, can be viewed in a single document (for example in a proceedings volume). Geosynthetics other than geomembranes also need to have focused attention. Joining of geonets used for liner drainage systems need attention as do drainage geocomposites used in landfill covers and closures. Without continuity of flow in geonets and geocomposites, a liquid management design strategy is of little value. The seaming of geogrids and geotextiles can also be important in an overall systems context. Where stress is to be transferred from one panel to the next, the nature and quality of the seams are all important. Application areas here are embankments, berms, walls, subsidence abatement, etc. With the above thoughts in mind, it was decided that a Seminar focusing exclusively and entirely on geosynthetic seams was advisable and even overdue. It is hoped that by gathering experts in seaming within the scope of their particular types of materials, an important forum for technology transfer will come about. The subsequent proceedings will thus form an important publication in the proper use of geosynthetics.

PROCEEDINGS OF THE PREDICTVION SYMPOSIUM ON A REINFORCED EMBANKMENT ON SOFT GROUND The bound proceedings of this symposium held in September 1986 are now published. It comprises over 500 pages in four parts: (i) Papers describing the project, the engineering assessment and the design parameters; (ii) Predictions based on classical methods; (iii) Predictions based on numerical methods; (iv) Presentations of the measured field data, and performance, and a resum6 of comments by the delegates. Copies are available at £40-00 (including postage) from Dr R. H. Bassett, c/o Dept of Civil Engineering, King's College London, Strand, London WC2R 2LS.
OBITUARY It is with great regret that we inform the Geotextiles & Geomembranes readers that Professor K. Gamski (State University of Li6ge, Belgium) died on 16 September 1988. • Professor K. Gamski was one of the pioneers in the study of geotextiles and geomembranes. His interest in these products started in 1975 and in 1978 he created a RILEM Technical Committee on Testing of Geotextiles which was the first international group on that topic. Professor Gamski was the author of more than 200 publications, mostly related to geotextiles and geomembranes, and an organizer of many international conferences and seminars on geotextiles and geomembranes. In 1966, he created the Laboratory of Construction and Civil Engineering Materials at the State University of Li6ge. This now employs 25 people. ' Professor Gamski was appreciated for his knowledge of materials science and for his very warm nature. He will be greatly missed.
