Dynamics of subglacial floods

The Nye model of jökulhlaups is able to explain both their periodicity and even the detailed shape of the flood hydrograph. In this paper, we show how the model can be used to predict the shape of the hydrographs from the subglacial lake Grímsvötn beneath Vatnajökull in Iceland, and we comment on th...
