The funeral of environmentalist Dick Warner will take place on Tuesday at Glasnevin Crematorium in Dublin.
The award-winning broadcaster, perhaps best-known for his television series Waterways, died last Friday.
It is understood he became ill on a boat on the river Shannon near Ballinasloe, Co Galway. His funeral service will be held at 2pm.
President Michael D Higgins led the tributes over the weekend, describing Mr Warner as a dedicated environmentalist and a "wonderful film-maker, and his beautiful work on the canals of Ireland was outstanding".
“Only last month, at an event celebrating the 200th anniversary of the opening of the Royal Canal, I referred to his dedication and skill in describing the rich heritage of our inland waterways,” the President said.
