Short summary
Some recent studies show that the topography at the base of an ice shelf has consequences for its interaction with the ocean. To describe friction velocity in the melt parameterisation, we use a drag coefficient dependent on the distance of the first wet cell to the ice and the basal topography rather than a fixed-tuned parameter. We find that it is less dependent on the choice of vertical resolution and, while providing similar total melt, it gives more weight to highly crevassed areas.
