Photos of Ice Flood in Glacial River

Earlier this week we reported on an ice jam in glacial river Jökulsá á Fjöllum at Grímsstaðir (see map).

The ice that had formed on the banks and the surface of the river has broken into many fragments. Cold weather conditions and low river discharge have resulted in the formation of river ice and slush. A mixture of ice and slush extends for several kilometers upstream and downstream from Grímsstaðir.

This is probably the largest ice jam in the river since December 2010. The flow is moving slowly beneath the bridge at Grímsstaðir, where water is beginning to accumulate to the west of the bridge.

The Institute of Earth Sciences has processed a satellite image of Jökulsá á Fjöllum, showing the extent of the ice-jam in the river on 17 January 2015.The image is a radar view from the Sentinel 1 satellite of ESA; the jam shows up in pink along the river channel. Ice extends about 2 km south of the bridge, as well as reaching over 12 km northwards.
