Modelling glacial overdeepenings and future lake locations for the western Canadian Cordillera

The Canadian Western Cordillera is a glaciated region within Canada which has seen significant glacial retreat due to recent climatic warming – estimated glacial volume reduction by 70% by 2100. As a result of this glacier retreat, depressions beneath are exposed (known as glacial overdeepenings) and lakes begin to form, dammed by the bedrock or deposited moraines. These can have important consequences both in terms of hazards and the possibility of economic benefits, including hydroelectric dams and a water resource. This research aims to predict where these glacial overdeepenings may occur under the present-day glacial ice in the British Columbia and Alberta glaciers. We will estimate the depth and volume of the potential lakes and understand how they will develop by using modern-day analogues, currently transitioning from a glaciated to deglaciated environment. This will aid future decision making of the local governments into water availability in an unpredictable climate.
