This year, ourspeaker will be Dr. Faye Hicks, one of the leading experts on river ice, a subject of obvious importance to anyone studying rivers in Canada. Dr. Hicks is a professor at the University of Alberta, where she teaches undergraduate and graduate courses in hydraulics, and has research interests in the areas of river ice processes and hydraulics, ice jam flood forecasting, and environmental impacts of river ice.
From her webpage, you can see her many interests, teaching, and awards, including recent ones for outstanding contributions to the development and practice of
hydrotechnical engineering in Canada, and modernization of the provincial river ice program, as well as the highest award given to professors at University of Alberta, and a mentoring award from the Alberta Women's Science Network.
The lectures will take place as follows: Hynes Lecture Part 1 2009: Wednesday, October 21st, public lecture at 7 pm in Fredericton (Room 146, Bailey Hall); Hynes Lecture Part 2 2009; Thursday, October 22nd, scientific lecture at 11:30 am at Ganong Hall Room 115, UNB Saint John.
The Weird and Wonderful World of River Ice, Wednesday, 21st October, 2009; 7 pm in Loring Bailey Hall, room 146, University of New Brunswick, Fredericton.
Each year, as winter approaches, our Canadian rivers undergo a magical transformation as flowing water begins to freeze. Whether it is frazil ice, hanging dams, hummocky ice, anchor ice, ice jams or even ‘pizza' ice - the processes that form river ice are beautiful and fascinating. Perhaps you have never noticed the complexities of river freeze-up and would like to learn more, or maybe you have witnessed these processes many times and would just like to know exactly why these strange things happen?
In this presentation, we will explore both freeze-up and breakup processes on rivers, through a combination of photographs and video clips. Learn why some rivers never freeze over, why anchor ice is dangerous to fish and why some rivers freeze from the top down, while others do the opposite. Witness the awesome power of river breakup, and the fearsome nature of the flash floods caused by ice jams as they form and release. Learn how river ice engineers and scientists study and predict these complex natural phenomenon. Together we will visit some of Canada's most remote, dynamic and beautiful rivers as they experience the weird and wonderful world of river ice. For a video of this lecture please Click Here.
Predicting Dynamic River Ice Processes, Thursday, 22nd October, 2009, 11:30 am in Ganong Hall, Room 115, University of New Brunswick, Saint John
River ice can be both beneficial and detrimental to Canadians. While ice roads and ice bridges provide essential transportation links to Canada's north, ice jams can cause flash floods that threaten lives and property with little or no advance warning. Of increasing concern are the potential impacts of human influences on river ice processes, both directly in terms of hydro-power development and indirectly in terms of climate change.
In this lecture, we will explore complexities of dynamic ice processes through a combination of photographs and video clips. Specifically, you will see the many ways in which river ice scientists and engineers use experimental and field studies to expand our knowledge and understanding of river ice dynamics. With an emphasis on processes, problems and solutions, rather than the underlying math-physics, we will also examine the new developments in computer modeling aimed at predicting ice jam floods, as well as the influences of hydro-power development and climate change on the ice regime of rivers. We will also examine the implications of this research for a variety of water resources engineering and ecological applications, including flood forecasting, and the assessment of winter water supply and physical fish habitat.
