The current increase in temperature over Greenland and other glaciated
regions allows for more surface melt, which poses the question of the
impact of this extra amount of meltwater on ice dynamics. As subglacial
hydrology models evolve they are now easier to apply to realistic
scenarios to quantify the effect of an increase in melt on the dynamics
of glaciers. However, a number of processes linking the surface melt to
the water pressure at the base of glaciers are still overlooked in
models due to a lack of knowledge or an excess of complexity. Here, we
apply a subglacial hydrology model coupled to an ice dynamics model to a
synthetic geometry to investigate the impact of moulins distribution on
the dynamics of the glacier. Our results show that a sparser
distribution of moulins leads to the faster development of the efficient
drainage system and greatly slows down the glacier.
