Simulation of the evolution of Breidamerkurjökull in the late Holocene
We have simulated the advance and retreat of Breidamerkurjökull, a tidewater glacier in Iceland, by means of a one-dimensional numerical ice flow model. The calculations were done with two different schemes for iceberg calving, the flotation model and the water depth model. The model simulates the g...
