Activities
International River Symposium
The International River Foundation hosts the International River Symposium conference annually in Brisbane, Australia. The event is intended to promote knowledge exchange among global river practitioners. The first International River Symposium was held in 1998 as part of the Brisbane Festival, prefiguring the founding of the International River Foundation.Brisbane Declaration
The 10th International Riversymposium and International Environmental Flows Conference was held in September 2007 and attended by over 750 delegates from more than 50 countries. The event resulted in a consensus document known as the Brisbane Declaration and Global Action Agenda, which is considered a significant landmark in setting international goals for environmental flows in freshwater-dependent ecosystems among scientists and water management practitioners.Thiess International River Prize
The International River Foundation awards the Thiess International River Prize for excellence in river restoration and management. The prize is presented from a slate of finalists during the annual International River Symposium. First presented in 1999 prior to the founding of the International River Foundation, the award is considered by some to be the most prestigious honor in the field of river restoration.
