Record #155503:

An ice-dammed lake in Jökulsárgil: predictive modelling and geomorphological evidence / Fiona Tweed.

Title: An ice-dammed lake in Jökulsárgil: predictive modelling and geomorphological evidence / Fiona Tweed.
Author(s): Tweed, Fiona.
Date: 2000.
In: Jökull. (2000.), Vol. 48 (2000)
Abstract: River was once dammed by glacier, forming lake from which major hlaups last occurred in 1930s. Most of year, river now forms tunnel. Paper discusses tunnel closure processes and ice-dammed lake formation, using models of tunnel dynamics and field data. Closure is more likely to be in winter, when flow cannot match overburden pressure. Cross-section is not that commonly used, since it is broad, low and weaker than semi-circular tunnels oftem used in models.
