Abstract
Analogue models are useful tools in earth science studies. They allow for the observation and analysis of phenomena that may otherwise be inaccessible or unobservable in the field. An analogue model was constructed in order to model the behaviour of flow in a valley glacier. The flow dynamics of a valley glacier can be disrupted by constrictions within the valley. Such constrictions can be geological, as in the case of bedrock sills, but it has also been suggested that ice from tributaries flowing into a trunk glacier may provide a blockage of the trunk’s flow. In our model, unobstructed and obstructed flow of an ice analogue material are analysed by the placement of constrictions in the valley. A strain grid was placed on the surface of the ice analogue material and flow was recorded by means of time lapse photography. Analysis can then be conducted on the collected images.
