Short summary
We use a new process-scale model for the drainage of active subglacial lakes in Antarctica that considers channel incision into the soft sedimentary bed. Compared to models with ice-incised channels, our model better reproduces magnitudes and recurrence intervals of active subglacial lake fill–drain cycles derived from satellite altimetry observations.
